In the early 1920s, Tsuneji "Thomas" Sato (1882-1969) found himself in the middle of a Michigan lumber camp on the opposite side of the world from his birthplace in Japan. Working with precision and productiveness and, most importantly, personality, Sato  served a hot meal to a group of vagabonds who, although weary from their travels, had no apparent reason to be weary at all. Sato knew that firsthand, as he and his co-workers had been the ones responsible for getting this party — and their extravagant  caravan — over hills, across rivers and through the wilderness.

While the lumber camp was obscure, the camping party’s members certainly were not, as Sato’s employer was the man who needed the vast swaths of hardwood being extracted out of Michigan’s northern forests at this camp, and others, to feed his automobile manufacturing machine, Ford Motor Company. At the heart of the company’s brand recognition was the polarizing, do-it-yourself folk hero Henry Ford whose wealth contradicted his own populist ethos and whose life was wholly dependent on a group of people who made things happen for him. A group, for some time, that included Sato. So much so that Ford postponed this trip just to ensure that Sato could make it work around his own personal schedule.

In some sense, the Fords were no different than other wealthy families of the early 20th century who had the means to staff their homes, preferring to hire domestic servants from a growing Japanese immigrant population generalized at the time as “polite, careful, clean, ambitious, and intelligent.” Japanese immigration to the United States had gradually increased over the late 1800s as the notoriously insular empire emerged from isolation and struggled with the abrupt pace of industrialization, regional war and a northern famine. By the early 1900s, hundreds, if not thousands, of Japanese immigrants were finding employment success in America’s household services sector, but a general spike in immigration began escalating a nativist angst among white Americans.

A furor of anti-Asian discrimination and violence, especially on the West Coast where Asian American communities were expanding, eventually led to an informal agreement between President Theodore Roosevelt and Japan, known as the Gentleman’s Agreement of 1907-1908, which restricted immigration from Japan until the Immigration Act of 1924 ultimately banned immigration from Asian regions altogether. Despite increasing xenophobia and restrictions, Tsuneji’s brother Junjiro (1870-1957) left their hometown of Wakuya, located in Japan’s northern prefecture, Miyagi, and made his way to the United States in 1894. At some point in the next 20 years, his younger brother Tsuneji would join him.

Upon the completion of Henry and Clara Ford’s sprawling Fair Lane Estate in 1915, Clara Ford contacted the Japanese Reliable Employment Agency of New York City looking for help. The Fords' former Japanese domestic servants, a couple who had worked for them at previous homes, wanted more for their lives in America: their own house and the ability to chase their own dream. Henry Ford obliged and gave the husband a job at his Highland Park plant, leaving Clara to inquire for someone who was single and “not as attached.” What the Fords received in Tsuneji Sato, now with the adopted English name of Thomas, was someone highly regarded who had the charisma and work ethic that could keep up with the unusual demands of an automobile magnate’s family.

For centuries in America, Black history has been relegated to the margins, with stories of Black lives only recorded by those who had the means or the motivation—or perhaps the hope that future generations would value them. The second-class treatment of Black history, the result of entrenched sociocultural discrimination, is painfully obvious to historical professionals looking to the written record for answers about the past lives of Black Americans.

While a major discrepancy still exists between the quality and quantity of Black historical records when compared to white counterparts, scholarship and re-examination, aided by new technologies, have helped in making new and old information alike more accessible. With barriers to information accessibility lessened to some degree, assembling these pieces of information into individual stories remains the biggest and most puzzling challenge. A prime example of this challenge can be found in the analysis of a document from The Henry Ford’s Digital Collections—an 18th-century apprenticeship contract.

Printed document with hand-written cursive notes and signatures
This apprenticeship document was gifted to Henry Ford in 1928 by William Van Rensselaer Abdill of Titusville, New Jersey. Abdill was a well-known collector whom Ford and others called upon to locate certain objects from history. This item was most likely part of a larger document collection that Abdill had amassed. / THF129623

On the surface, this apprenticeship document shows no indications of being related to Black history, but a careful examination proves otherwise. To start, there’s a name, “John Thompson” (or “John Thomson,” as signed at the bottom); there’s an age, “fourteen years, eight months, twenty-seven days”; and there’s a date, September 11, 1794. Other information from the document tells us that John Thomson was from Salem, Massachusetts, and was apprenticing to be a “mariner.” A careful sifting of this information through genealogical resources reveals that in May of 1809, this same John Thomson applied for a Seamen’s Protection Certificate. The application confirmed Thomson’s birth in 1780 in Salem, Massachusetts, and described him as a “negro, born-free.”

Reproduction of printed document with handwritten, cursive text
John Thomson’s application for a Seamen’s Protection Certificate included identifying information. The document states he was about five feet, three inches, in height and had several scars above his left eyebrow, as well as a scar from a smallpox inoculation on his left elbow and marks from a dog bite on his left arm. / Citation: The National Archives and Records Administration; Washington, D.C.; Proofs of Citizenship Used to Apply for Seamen's Certificates for the Port of Philadelphia, Pennsylvania, 1792-1871

Further historical context helps illuminate John Thomson’s life and experiences. During the “Age of Sail,” when global commerce was facilitated by sailing ships, the city of Salem, Massachusetts, was a bustling international port. In the centuries before Thomson’s apprenticeship, slavery played a major role in Salem’s maritime economy, not only in the city’s involvement in the slave trade, but in the lives of those who worked its ships and docks. Even after Massachusetts became the first state to abolish slavery in 1783, slavery’s discriminatory legacy continued. As one of the few occupations open to them, free Blacks found life on the sea as a sailor to be a more integrated and less racially tense working environment. In port cities like Salem, these kinds of employment opportunities helped lay the foundation for Black communities in the early years of America.

John Thomson’s 1794 contract also reveals clues about how the then-14-year-old spent the next six years of his work life apprenticed to Captain Robert Emery on the ship Diana. Information on the ship and its captain (in contrast to Thomson) is plentiful. We know that the Diana was built in 1790 up the coast in Amesbury, Massachusetts, and was used to carry trade with Europe. Sometime in 1793, a change of ship masters occurred in New York City and the Diana was transferred to Emery, who was merely 20 years of age at the time.

Portion of document with printed and handwritten, cursive text
Information from the first part of the document tells us that Robert Emery was the master of the ship Diana (whose owners were based in Boston), and that John Thomson’s apprenticeship would last just over six years. / THF129623, detail

In 1794, Emery was hiring a crew for an upcoming trip to Bristol, England, and needed an apprentice. Apprenticeships were standard in a variety of trades during this period of American history. Usually, a boy of about 13 or 14 would be indentured to a master until he reached the age of 20 or 21. In return, the master would provide food, clothing, shelter, and, most importantly, training. For Black adolescents like John Thomson, whose opportunities were limited, a stable source of food, clothing, and training could be life changing. Racially integrated crews were common for ships sailing out of Northern port cities. In 1805, five years after Thomson’s apprenticeship ended, Emery hired another racially integrated crew to sail out of Salem for India aboard the vessel Golden Age. Among the group were two local Black men: a “first mate” (next rank under captain) and a “boy” (another name for an apprentice).

As part of the agreement, John Thomson would be provided “meat, drink, apparel, washing and lodging” during his apprenticeship. / THF129623, detail

Threats abounded for Black sailors when John Thomson agreed to his apprenticeship contract in 1794. A year earlier, the 1793 Fugitive Slave Act was passed, giving slaveholders the right to recover an escaped slave. Abuse of the law began immediately, as it offered no procedural protections for free Blacks to avoid being seized as slaves—no right to a lawyer or a trial by jury, or even to speak on their own behalf. Furthermore, the British were struggling to staff a massive navy and actively forced thousands of unwilling American sailors into service. In an effort to stop illegal impressment by the British, Congress began issuing Seamen’s Protection Certificates in 1796, which worked as identification papers and proof of a sailor’s American citizenship. These kinds of papers would have been doubly important to Black sailors who were also under constant threat of being enslaved.

“J.W. Keese” of the “City of New York” notarized the agreement at some point in time. / THF129623, detail

In the years preceding Seaman’s Protection Certificates, around the mid-1780s sailors began carrying papers that helped prove their identity. These could have been copies of parish or town records or a notarized statement by a reputable person who could attest to the bearer’s American citizenship. Notarizing this apprenticeship document, most likely Thomson’s only proof of identification, would have been vitally important. The writings along the side of the document speak to this, as they show that this document was notarized by John Keese of New York City—a notary public, attorney, and founding member of the New York Manumission Society. As New York was a major port city, it’s likely Thomson would have been there at some point, and while the Manumission Society played a paternalistic guardian role in lives of New York’s slaves and free Blacks, it would have been one of the only groups advocating for Black rights in general. For free Blacks like John Thomson, having Keese’s name on the document carried weight if anyone questioned his identity.

We know little about Thomson’s time on the Diana, except for the fact that at some point in the late 1790s, Emery armed the ship for protection against the French. According to the reverse of the contract, Thomson’s apprenticeship ended in Salem in 1800. Details about the remainder of Thomson’s life and career remain lost (or at least very well hidden) to history—whether or not he had a family (some sources suggest he married Violet Wilkins in 1817), if he joined fellow Black sailors in defending the nation during the War of 1812, or even when he died. What has endured though, are the pieces of information that provide enough clues to tell a meaningful part of Thomson’s story—and offer an important lens into the lives of early Black Americans.

Long black piece of machinery
THF140091
The cast-iron lathe shown above, dating to the 1860s, proved the wood-cutting prowess of inventor Thomas Blanchard’s original 1818 design. While today it is motionless in the Made in America exhibit in Henry Ford Museum of American Innovation, when in-motion, Blanchard’s lathe was a pivotal technological development in standardization and mass production during the Industrial Revolution. Its ability to duplicate or copy irregular wood designs was a big improvement on the time-consuming and skill-demanding task of carving wood products by hand. Originally built for manufacturing rifle stocks at Blanchard’s employer, the Springfield Armory in Massachusetts, the lathe found usage in other industries, like creating shoe forms that helped standardize shoe sizes.

The lathe could be used by semi-skilled operators and made copies using a rotating blade whose position was guided by the shape of a prototype—similar to today’s modern key-cutting machine. Much like the movements of a cutting tool against a key blank are constrained by the shape of the original key, Blanchard's lathe consists of a frame into which a master pattern and a blank can be fixed. A carriage, responsible for guiding the cutting tool, then moves the length of the lathe carrying a revolving cutter and what Blanchard termed a friction point. The carriage’s position against the master pattern determines the degree to which the cutter bites into the blank. The major difference between the key-duplicating machine and Blanchard's lathe is that the former cuts a profile in the edge of a key, while Blanchard's lathe was designed to shape a three-dimensional duplicate of the master pattern.

Not only was Blanchard’s lathe an early example of a machine that could be programmed, but its ability to duplicate irregularly shaped, three-dimensional objects ushered in a wave of standardized interchangeable parts that reshaped the trajectory of the Industrial Revolution.

With the rise of the suburban neighborhood at the end of the 19th century and its explosive growth in the years that followed World War II, maintaining a "perfect" lawn became the new standard. Manufacturers promoted a whole set of specialty equipment to support this American obsession. / THF620523


A quintessential icon of modern American suburbia, the “lawn” has roots as deep as America itself. In the early days of the nation, the importation of European taste highly influenced the architecture and interior decoration style of the wealthy—which included the adoption of the green spaces that began appearing in French and English landscape design during the 18th century.

During his time representing the young United States in Europe, Thomas Jefferson witnessed the “tapis vert,” or “green carpet,” at the Palace of Versailles, as well as the large green swaths of closely mown grass that were common to English country estates. Both impressed upon Jefferson a grandeur that he tried to emulate at Monticello, his plantation. This European influence also extended to George Washington’s Mount Vernon plantation, where Washington hired English landscape gardeners to help create his own versions of English lawns and gardens.

These plantation sites were heavily enmeshed in the American psyche as Washington and Jefferson became mythologized over time. During the 19th century, inexpensive and easily acquired prints made both of these plantation homes, including their grounds, some of the most famous buildings in America, and gave wealthy Americans images of what they could aspire to.

In the mid-19th century, citizens of increasingly industrialized cities with growing populations sought respite from the urbanization of their landscape. A solution to their problems came in the form of advocacy by prominent landscape designer Andrew Jackson Downing for the creation of suburbs outside cities, as well as public parks. When Downing died unexpectedly in 1852, Frederick Law Olmsted stepped up to deliver on Downing’s visions—and bring to life some of his own.

Often considered the father of American landscape architecture, Olmsted started his career in the 1850s when he co-designed New York City’s Central Park with architect Calvert Vaux. He’d go on to design parks in Boston, Chicago, Montreal, and many other places. Olmsted not only popularized the use of green spaces in public parks, but also co-designed suburbs with Vaux—like Riverside, Illinois, in which each residential home had its own lawn or “green space.”

Riverside, Illinois, marked the beginning of the migration that lawns took from city parks and wealthy estates to individual yards. By the 1890s, they were becoming a fixture of the suburban landscape as improvements in transit allowed city suburbs to grow.

With this new hobby came new technology. Enhancements to mass-production procedures over the course of the 19th century meant new machinery, like mechanical mowers, could be manufactured at a relatively low cost to help homeowners keep their lawns trimmed (no more sheep or servants needed!). While sprinklers would require cities to invest in and build municipal water systems, the ability to own a home with a lawn was slowly becoming possible for more and more Americans as infrastructure advanced in the early 20th century. Over the next 50 years, what was once uncommon would become synonymous with suburban living.

The mid-20th century saw the maturation of modern American lawn culture—a culture that remains relatively unchanged today. The unprecedented economic growth of post–World War II America brought a need for inexpensive housing to accommodate returning GIs and their young families. An early solution to this problem was Levittown, New York, one of the first “cookie-cutter” affordable-housing suburbs, built between 1948 and 1952 by Abraham Levitt on Long Island. The easy-to-manufacture homes of Levittown came with a lawn—along with rules on how it should look—and represented the suburbanization that was taking place across American cities at the time.

Today’s lawn standards arise from the scientific and technological developments of the post-war period, when rotary mowers were introduced along with a number of pesticides and fertilizers now needed to keep a lawn “healthy.” Since then, the lawn has become ubiquitous in suburban living and a symbol of the middle-class American dream, as well as a big business. While the pursuit of a perfect lawn remains a pillar of identity in America, shifting cultural perceptions around how environmentally sustainable lawn culture is continue to shift the conversation on this icon of American communities.

Image of Martha Coston from her 1886 autobiography. (Not from the collections of The Henry Ford.)

Inventor Martha Coston overcame 19th-century gender stereotypes to help change the course of the Civil War, as well as boating safety. In 1848, tragedy struck when Martha’s husband, a successful inventor formerly employed in the Washington Navy Yard, died as a result of chemical exposure from his gas lighting experiments. His death was followed by the deaths of two of their children and a mother Martha was close to, and a relative mishandling Martha's remaining money. Martha was left a single mother with minimal support.

Martha needed a way to support herself and her two remaining children. Within her husband's papers, she discovered drawings for a pyrotechnic night signal that could be used by ships to communicate. After finding that the invention didn't work, she took on years of experiments in hopes of creating a functional signal flare. With no knowledge of chemistry or scientific methodology, Martha relied on others for help. Men often ignored her, didn't take her seriously, or deceived her.

The signal set used three colors to create coded messages. As a patriotic woman, Martha wanted flares that burned red, white, and blue. While she had developed recipes for red and white, blue remained elusive. A breakthrough came in 1858, when Martha was in New York City watching fireworks during celebrations for the first transatlantic cable.

Inspired by the fireworks, Martha wrote New York pyrotechnists looking for a strong blue, corresponding under a man's name for fear that she would be ignored. Instead of a blue, Martha was able to locate a recipe for a brilliant green. In 1859, Patent No. 23,536, a pyrotechnic night signal and code system, was granted, with Martha Coston as administrator—and her late husband as the inventor.

The U.S. Navy showed high interest in Martha's invention, but stalled the purchase of the patent until 1861, after the Civil War erupted. With a blockade of Southern ports in place, the Navy needed Martha's flares to communicate. Her business, the Coston Manufacturing Company, produced the flares and sold them at cost for the duration of the war. New York gun manufacturer William Marston produced the signal pistol above to exclusively fire Coston's multicolored signal flare.

In her 1886 autobiography, A Signal Success: The Work and Travels of Mrs. Martha J. Coston, Martha acknowledged the use of her flares in the success of the blockade. Confederate ships known as blockade-runners regularly sailed at night, and Coston's flares helped Union ships pursue these runners effectively, often resulting in prize money for the ship's officers. Admiral David Porter, pictured on the right above, wrote Martha about the impact her flares had on military operations, saying:

"The signals by night are very much more useful than the signals by day made with flags, for at night the signals can be so plainly read that mistakes are impossible, and a commander-in-chief can keep up a conversation with one of his vessels."

In January 1865, Wilmington, North Carolina, remained the last open port of the Confederacy. To cut the port off, Admiral David Porter and Major General Alfred Terry coordinated a joint assault of sea and land forces. The ensuing conflict, known as the Battle of Fort Fisher, resulted in a Union victory.

According to Admiral Porter, Martha Coston's flares played a critical role. He later reminisced, "I shall never forget the beautiful sight presented at ten o'clock at night when Fort Fisher fell.... The order was given to send up rockets without stint and to burn the Coston Signals at all the yard-arms."

After the war, Martha Coston continued to improve upon her invention, filing several more patents—this time in her own name. When the United States Life-Saving Service, precursor to the United States Coast Guard, began using the Coston flare, Martha's invention became standard safety equipment for all boating vessels. Worldwide adoption of her invention led to the success of Martha's business, Coston Supply Company, which focused on maritime safety and stayed in business until the late 20th century.

Washington DC, 19th century, women's history, inventors, Civil War, by Ryan Jelso, #THFCuratorChat

Claude Harvard faced many racial obstacles over the course of his young life, but when he addressed a crowd of students at Tuskegee University in 1935, he spoke with confidence and optimism:

“Speaking from my own experience, brief as it is, I feel certain that the man or woman who has put his very best into honest effort to gain an education will not find the doors to success barred.”

One of the few, if not the only, Black engineers employed by Henry Ford at the time, Claude had been personally sent to Tuskegee by Ford to showcase an invention of his own creation. Even in the face of societal discrimination, the message of empowerment and perseverance that Claude imparted on that day was one that he carried with him over the course of his own career. For him, there was always a path forward.

Born in 1911, Claude spent the first ten years of his life in Dublin, Georgia, until his family, like other Black families of the time period, made the decision to move north to Detroit in order to escape the poor economic opportunities and harsh Jim Crow laws of the South. From a young age, Claude was intrigued by science and developed a keen interest in a radical new technology—wireless radio. To further this interest, he sold products door-to-door just so he could acquire his own crystal radio set to play around with. It would be Claude’s passion for radio that led him to grander opportunities.

At school in Detroit, Harvard demonstrated an aptitude for the STEM fields and was eventually referred to the Henry Ford Trade School, a place usually reserved for orphaned teen-aged boys to be trained in a variety of skilled, industrial trade work. His enrollment at Henry Ford Trade School depended on his ability to resist the racial taunting of classmates and stay out of fights. Once there, his hands-on classes consisted of machining, metallurgy, drafting, and engine design, among others. In addition to the manual training received, academic classes were also required, and students could participate in clubs.

As president of the Radio Club, Claude Harvard became acquainted with Henry Ford, who shared an interest in radio—as early as 1919, radio was playing a pivotal role in Ford Motor Company’s communications. Although he graduated at the top of his class in 1932, Claude was not given a journeyman’s card like the rest of his classmates. A journeyman’s card would have allowed Claude to be actively employed as a tradesperson. Despite this obstacle, Henry Ford recognized Claude’s talent and he was hired at the trade school. By the 1920s, Ford Motor Company had become the largest employer of African American workers in the country. Although Ford employed large numbers of African Americans, there were limits to how far most could advance. Many African American workers spent their time in lower paying, dirty, dangerous, and unhealthy jobs.

The year 1932 also saw Henry Ford and Ford Motor Company once again revolutionize the auto industry with the introduction of a low-priced V-8 engine. By casting the crankcase and cylinder banks as a single unit, Ford cut manufacturing costs and could offer its V-8 in a car starting under $500, a steal at the time. The affordability of the V-8 meant many customers for Ford, and with that came inevitable complaints—like a noisy rattling that emanated from the engine. To remedy this problem, which was caused by irregular-shaped piston pins, Henry Ford turned to Claude Harvard.

To solve the issue, Harvard invented a machine that checked the shape of piston pins and sorted them by size with the use of radio waves. More specifically, the machine checked the depth of the cut on each pin, its length, and its surface smoothness. It then sorted the V-8 pins by size at a rate of three per second.  Ford implemented the machine on the factory floor and touted it as an example of the company’s commitment to scientific accuracy and uniform quality. Along with featuring Claude’s invention in print and audio-visual ads, Ford also sent Harvard to the 1934 World’s Fair in Chicago and to the Tuskegee Institute in Alabama to showcase the machine.

During his time at Tuskegee, Harvard befriended famed agricultural scientist George Washington Carver, who he eventually introduced to Henry Ford. In 1937, when George Washington Carver visited Henry Ford in Dearborn, he insisted that Claude be there. While Carver and Ford would remain friends the rest of their lives, Claude Harvard left Ford Motor Company in 1938 over a disagreement about divorcing his wife and his pay. Despite Ford patenting over 20 of Harvard’s ideas, Claude’s career would be forced in a new direction and over time, the invention of the piston pin sorting machine would simply be attributed to the Henry Ford Trade School.

Despite these many obstacles, Claude’s work lived on in the students that he taught later in his life, the contributions he made to manufacturing, and a 1990 oral history, where he stood by his sentiments that if one put in a honest effort into learning, there would always be a way forward.

Today, the portability of audio entertainment has become second nature to most people around the world. With relative ease, a person can put in/on a pair of headphones, wirelessly connect to a handheld device of their choosing and pick from a wide variety of options, including music, podcasts, audio books, etc. While we have become accustomed to this comfort and convenience today, in the early 1920s, “portable” and “wireless” tech, like the battery-powered “Pocket Radio” manufactured by the Auto Indicator Company of Grand Rapids, Michigan, was considered cutting edge in the audio entertainment industry.

The roots of the portable nature of the Pocket Radio can be traced back to Thomas Edison’s 1877 unveiling of his phonograph. The machine, which was the first to practically demonstrate that sound could be recorded and reproduced, proved that an audience didn’t have to be physically present in order to enjoy a listening experience. By the 1910s, subsequent improvements of the phonograph by other inventors and companies had brought a booming audio entertainment industry to the masses.

Consumers grew used to the idea that the sounds they enjoyed could be listened to on their own time and in their own space – all with the help of their own personal phonograph. When World War I broke out, portable versions of phonographs found their way to the front lines not only for military use in the training of recruits, but also to entertain troops. The much-needed musical reprieve provided through a phonograph boosted morale by helping soldiers, individually or in groups, briefly escape the terror happening around them.

Wartime also provided an opportunity to explore another cutting-edge technology that had gained traction before the war – wireless communication in the form of radio waves. During World War I, the U.S. government took over the fledgling radio industry and instituted a ban on civilian use of radio in order to further their wartime experimentation. After the war, the ban was lifted in 1919, and by mid-1922 a “radio craze” was sweeping the nation, as Americans became infatuated with the new technology. Around the country, broadcasting stations began to spring up to serve the thousands of listeners seeking to tune in to hear music, news and more.

In 1924, partners in the Auto Indicator Company of Grand Rapids sought entry into this market with their Pocket Radio. As one of the first companies to patent and manufacture signal lights for automobiles, their demonstrated business savvy showed they understood that the increasing affordability of the automobile and a booming post-war economy meant more consumers on the go – and these consumers wanted to take their audio entertainment with them.

By today’s standards, the four pound (12 x 3 x 3 inches) “Pocket Radio” would not be considered “pocket-sized.” But in 1924, the summer tourist or picnicker that bought this radio for $23.50 would have understood that “pocket” referred to the pocket door of an automobile, where the radio could be stored. Without having to worry about bringing physical records to play on a portable phonograph or lugging around an early battery-powered table-top sized radio, a Pocket Radio owner could tune in to any broadcast station within five miles, and, with the addition of an aerial or ground receiver, could listen to a broadcast station that was 1,000 miles away.

A seemingly smart product, the Pocket Radio didn’t bring the business partners of the Auto Indicator Company much success. By the mid-1920s, they had given up on the radio and molded their former business into the Multi-Selecto Phonograph Company, an unwise decision in a turbulent time. Throughout the 1920s, while the phonograph remained a viable product, the industry underwent significant strain with the changes brought on by the advent of the “Golden Age of Radio.” While companies tried to stay afloat by selling hybridized products that combined the radio and the phonograph, like many other phonograph companies of the time, the Multi-Selecto Phonograph Company wouldn’t make it out of the Great Depression.

Today, the Pocket Radio serves as documentation of an exciting time in the history of technology, where new ideas met at a crossroads to provide the consumer with more personal freedom in how and where they enjoyed their entertainment choices.

Over the course of a few short weeks, our daily lives have been disrupted in an unprecedented way. For most of us, our daily schedules no longer require moving from place to place — from our homes to our workplaces, miles away.

In our rush to get to the next location, did we ever stop to think about the space we traveled through to reach our destination? Did we ever stop to admire the natural world that envelops our civilization?

We hastily moved through the world. Now, while many of us are temporarily stationary, the natural world continues its movement around us. This presents a unique opportunity. With less demand on where you have to be, take this chance to enjoy the beauty of that motion. All it takes is a look out the window or a step out the door.

Here are the stories of a few makers and doers from The Henry Ford’s collection whose connection to the natural world might just help you step back, admire, reconnect and recharge:

- Learn more about the life of naturalist and writer John Burroughs in this Google Arts & Culture digital exhibit. Or take a look through pressed wildflowers Burroughs collected on an 1899 trip to Alaska in this album.

- Agricultural scientist George Washington Carver was committed to teaching, serving the community and making a difference. Learn more about his work in this blog. Or take a read through one of his publications used by educators to teach kids about gardening.

- Glass artist Paul Stankard, considered one of the fathers of the studio glass movement, drew upon a deep connection with the natural world to intricately replicate flowers and other botanicals in his acclaimed paperweights. Learn more about Stankard’s life, work and inspiration through his own words in this Visionaries on Innovation interview.

- Before starting a national conversation on the use of pesticides, author Rachel Carson found success with her poetic book  The Sea Around Us. A New York Times bestseller for nearly two years and winner of the John Burroughs Medal for nature writing, Carson's work can be checked out virtually for those who can’t make it outdoors.

Whether it’s a new flower blooming or the birds singing outside your window, find solace in the simple beauty of the world around you. Who knows, maybe the inspiration you find will lead you to spark a change in your own way.

Actually, the Tri-Motor of this story wasn't small at all. The all-metal airplane was rugged, dependable and equally adaptable to passenger and freight service. Built by Ford Motor Company from 1926 to 1933, the Ford Tri-Motor flew in many early American airline fleets and became the most popular airliner of the late 1920s and early 1930s.

In all, 199 Tri-Motors were built during its seven-year production run. Over the course of their lives, many of the planes found varying uses, including the 48th Tri-Motor built, purchased in 1928 by Reid, Murdoch & Company. The manager of the sales department for Ford's Lincoln division, Arthur Hatch, had completed the sale of the plane while traveling by train with the president of Reid, Murdoch, & Company. The Chicago-based company had big plans for their Tri-Motor and turned its interior into a showroom for their Monarch Foods brand. A few of the canned items stocked on the plane included sweet pickles, peanut butter, popcorn, toffees, sardines, peas, asparagus, lima beans and corn.

When it came time for the delivery of the Tri-Motor, the president of Reid, Murdouch & Co. insisted on coming to the Dearborn, Michigan, plant to personally turn the check over to Arthur Hatch. Named "Independence," the modified plane began its life as a flying salesroom, carrying samples of over 200 different food products to airports throughout the country. Occasionally, Monarch's pint-sized advertising characters, "The Teenie Weenies," also accompanied the plane on its stops.

The Teenie Weenies
, a popular comic strip created by cartoonist and author William Donahey, began appearing in the Chicago Tribune during 1914. The adventures of the 2-inch tall "Teenie Weenies" took place in a town made-up of buildings created from recycled household products like shoes or food containers. In 1924, the Chicago Tribune discontinued the comic series allowing Reid, Murdoch & Co. to take advantage of the characters for use in advertising their Monarch Foods brand. In the company's advertisements, the cartoon characters used Monarch food containers for their buildings. On occasion, real-life examples of the characters (child actors) made appearances with Monarch's Tri-Motor.

Besides the Ford Tri-Motor, the Teenie Weenies have another Michigan connection. On the shores of Lake Superior, east of Pictured Rocks National Lake Shore, sits a tiny town that goes by the name of Grand Marais. In the mid-1920s, Reid, Murdoch & Co. built William Donahey a summer cabin there. Inspiration for the building came right from Donahey's Teenie Weenies comic strip. The result – a building in the shape of a pickle barrel – today welcomes visitors as the Pickle Barrel House Museum.

Today, coffee and tea are enjoyed by millions of people, including blog readers. While connoisseurs of these beverages take their enjoyment very seriously, the relative affordability of these caffeinated drinks means that almost anyone can “benefit” from a caffeine boost and also enjoy their flavors. The resulting billion-dollar industries help power the world economy – and its workforce.

America has an especially close relationship with these drinks, one that dates back to before the country was formed. In modern times, coffee has dominated American tastes, but until the 20th century, Americans favored tea. Although still popular, tea drinking in America can be traced back to trade with China by Dutch merchants in the early 1600s.

THF102595

Today, fast-paced Americans prefer their caffeinated beverages on the go, often consuming them from disposable drinkware. This is in marked contrast to colonial America, where these beverages would have been served from vessels made to impress and consumed as part of elaborate entertainments expressing the host’s good taste. THF 102595


Dutch traders not only introduced Chinese tea to their colony in present-day New York, but also introduced it to Europe. The hot drink quickly rose in popularity and by the end of the 1600s, tea became the most favored hot beverage in Britain. To support the mass consumption by its citizens at home and in its colonies, England became heavily involved in the China trade and the importation of tea.  

As social customs evolved around the drinking of tea, so did the equipment used to consume the beverage. Wealthy citizens could afford to have their teapots fashioned in silver and silversmiths in the colonies, like Paul Revere, learned how to create silver designs from imported English examples. Son of Apollos Rivoire, a French immigrant and Boston silversmith, Paul Revere got his start as his father's apprentice.

After his father died in 1754, Revere started his career producing a wide variety of silver objects, including elaborate teapots for his wealthier clients. By the 1760s, the colonies faced increased taxation as England attempted to pay off their war debt from the French and Indian War. High taxes on imports like tea angered colonists, resulting in boycotts that affected what Revere could produce as a silversmith.

These taxes led Revere to join a resistance group known as the "Sons of Liberty" whose members included some of his customers angered by the increased taxation. The organization helped fuel anti-British sentiment in the colonies and Revere aided the groups’ cause by printing propaganda that provoked colonist anger towards the Crown.

As a member of the Sons of Liberty, Paul Revere helped energize the movement toward American independence by printing illustrations like this one of the Boston Massacre. An active citizen, he was part of numerous other civic organizations. THF 8141

In 1773, with tensions mounting, Paul Revere and the Sons of Liberty protested England's control over the tea trade by boarding recently docked British tea ships in the Boston harbor and dumping some of their tea chests overboard. The British responded to the event, known as the Boston Tea Party, by shutting the port of Boston and stripping the Massachusetts colony of its right to self-government. 

War erupted in 1775 when Britain moved to seize the colonists' gunpowder and firearms outside of Boston. Revere made his famous midnight ride during this time to warn some of his fellow patriots that the British were on their way to arrest them. While patriot duties limited Paul Revere's silversmithing during the Revolutionary War, he returned to his craft as the war came to an end in the 1780s.  

Post-war American silver customers preferred the neoclassical design that became popular in Europe during the war. In the years before the War, silver customers had preferred the Rococo style, an aesthetic known for its ornate decorations and curvilinear body designs. In contrast, neoclassical silver celebrated the classical style of Greece and Rome, making use of symmetry, hard lines, and an emphasis on simple forms. As a master craftsman, Revere developed an elegant and personal interpretation of the neoclassical style.

THF166149

This 1782 teapot shows Revere’s experimentation with the neoclassical style.


The neoclassical teapot shown above was created in 1782 by Revere. Only six teapots featuring this cylindrical body are known to exist and were some of the last that Revere hand-forged, hammering or "raising" them up from a block of silver. In 1785 Revere acquired silver rolling machinery that he used to produce silver sheets. These sheets were cut to form standardized pieces and allowed Revere's shop to produce silver products more quickly. An example of a Revere teapot made from this later method can be seen in our collections here.

THF166147

On the bottom of the 1782 teapot, the clear markings of Revere are stamped next to a monogram that can be attributed to Joseph and Sarah Henshaw of Boston. THF 166147

With the assistance of the Massachusetts Historical Society, home of the Revere Family Papers, Revere's own record books identified Joseph Henshaw as the patron for this teapot. The records show that on February 22, 1782 Paul Revere made a note that he needed to make a teapot and spoons for Joseph Henshaw. By April 27, 1782 it appears that Revere had completed the order and marked the weight of the teapot as "16-17". This weight of "16-17" can be seen scratched on the bottom of the teapot in the upper right of the picture above.

Joseph Henshaw was a prominent Boston merchant. With his wife Sarah, the two used their home to help plan further American resistance by occasionally hosting "Sons of Liberty" meetings. It was his membership in this radical group that led Joseph Henshaw to form a friendship with Paul Revere. While this teapot is a good representation of the tea culture that existed in the colonies, it is also a symbol of Revere and Henshaw's relationship, a relationship that helped establish the United States of America.
