How did a shirt pocket lead to a feat of engineering?
The origins of Hewlett Packard’s HP-35 Scientific Calculator began with a challenge. In 1971, William Hewlett dared his engineers to prove their engineering prowess by miniaturizing the company’s 9100A Desktop Calculator—a forty-pound machine—into a device small enough to fit into a shirt pocket. The calculator’s target size of approximately 6x3 inches was supposedly arrived at by measuring one of Hewlett’s own shirt pockets.
The twelve or so experimental HP-35s that began as "company hacks" soon proved useful beyond the prototype stage. They were popular among the staff who built and tested them, and were presented for marketing studies. Despite a high manufacturing cost driving a retail cost of $395 (equivalent to $2200 in 2015), and research that warned of a limited market, Hewlett-Packard decided to proceed with production. The company’s 1972 sales goal of selling 10,000 calculators was quickly exceeded: they sold 100,000. Its rapid success made the slide rule obsolete practically overnight, as engineers, scientists, and mathematicians abandoned their analog calculating devices in favor of embracing the digital future.
The HP-35 (named for its 35 keys) was the world’s first handheld scientific calculator. This advanced machine, with its full suite of features, was capable of processing more complex mathematical functions than any other calculator on the market at the time. It was also the company’s first product to use both integrated circuits and an LED display, which eased communication between the screen and keys. The HP-35 inspired others too—it caught the attention of a young Hewlett Packard engineer named Steve Wozniak. During the day, he worked at designing follow-up models of the calculator; in the evening, he developed his own electronic projects at home. All the while, he was percolating ideas towards the beginnings of the Apple 1 computer.

How did a weaving loom lead to one of the greatest technology innovations of the 21st century?
The Jacquard Loom was a significant breakthrough in the history of textile production, an essential manufacturing tool of the Industrial Revolution. Joseph Marie Jacquard, a silk weaver from Lyon, France, first demonstrated his improved drawloom at an industrial exposition in Paris in 1801. By 1803, a spark of genius inspired him to make another improvement to this loom—the “Jacquard attachment.”
This mechanism, mounted above the loom, uses a continuous chain of punch cards to control the lifting of individual threads. Each card on the loom corresponds to a hook, which can be raised or stopped depending on whether the hole is punched out or solid. The cards are mounted on a rotating cylinder and pressed against pins, which detect the presence of holes. The loom’s hooks are raised or lowered by a harness, which guides the thread to form a pattern in the fabric.
In a rare moment, one person’s simple act of courage can change the world. On the 60th anniversary of Rosa Parks’ refusal to give up her seat to a white man on a bus in Montgomery, Alabama, we pause to reflect on the impact and legacy of her courageous action.
Rosa’s awareness of social injustice started at an early age. As a girl growing up in Alabama, Rosa hated the disrespectful way that whites often treated black people. Her grandfather, a former slave, instilled a sense of pride and independence in her.
Our founder, Henry Ford, realized that not everyone learns best by reading books or listening to a lecture, the traditional modes of education he experienced 150 years ago which are still dominant today. One of Henry’s most important learning experiences was fixing pocket watches. He developed an understanding of engineering and science through hands-on, self-directed discovery. He founded The Henry Ford as a school, where children would learn by doing with the real stuff of history and science. He collected artifacts which showed hundreds of years of changes in technology and daily life, and allowed the children to use them.
Today, we still share with children the “real stuff” of history and science. Over 200,000 students are lucky enough to take a field trip to The Henry Ford each year. Although we’ve discovered we can’t allow many of our artifacts to be used to the degree they were in the 1930s, The Henry Ford has made historical artifacts more hands-on than most other history museums. On field trips, students literally go inside science and history when they fathom the overwhelming number of inventions at Edison’s Menlo Park Laboratory or explore (and smell) the Firestone Farm barn. Of course, there is no experience more powerful for our student visitors than taking a seat in the actual Rosa Parks Bus.
You may be wondering, besides Mold-A-Ramas and selfies with cool historic cars - what do students come away with?
Yes, they see examples of the “real stuff” which they learn about in Social Studies, Science and English Language Arts every day. And, they have had fun learning, which is vital to becoming lifelong learners. But the most important thing they get is a profound understanding that real people did these things which they study in school. Real people, just like them, changed the world. And they can, too.
On this #GivingTuesday, we hope you will consider making a gift of at least $8 to The Henry Ford. Your contribution makes these important field trips possible and helps us to inspire the next generation of innovators and change makers. You can make your gift below.

This is it – the future is now. For any self-respecting Child of the Eighties, October 21, 2015, has been circled on the mental calendar since November 1989 when Back to the Future Part II hit theaters. I was 13 years old when I first saw Doc Brown and Marty McFly take their time traveling DeLorean to the fantastically futuristic world of Hill Valley 2015 – old enough to realize that we probably weren’t going to get hoverboards and flying cars, but young enough to still hope that we might. The year 2015 seemed impossibly far off (like, as far off as 2041 seems today), and one could imagine that some of those wonderful things in the movie might just come to pass. Well, not so much…
Predicting the future is a fool’s errand. Any movie that tries to imagine future technologies will inevitably miss the mark. Back to the Future Part II’s creative team knew this well, so they chose to go all in and make their 2015 as over-the-top as possible. That tech optimism is a big part of the movie’s appeal. BTTF II gives us happy robots that pump our gas, serve our soft drinks, and welcome us home at the end of the day. They’re a pleasant contrast to the tortured replicants and cyborgs of Blade Runner and RoboCop.
Being a transportation curator, I thought it might be fun to take a look at some of the transport technologies featured in Back to the Future Part II. Let’s start with those flying cars. The dream of an aircraft in every garage is an old one. It shows up in books, magazines and – on rare occasions – in reality. (Even Henry Ford spent some time and money on the concept.) The flying cars in BTTF II are there because they have to be. It’s the future we all want! Needless to say, we didn’t get them by 2015. Personally, I think flying is well beyond the skills of the average driver (myself included). Flying cars aren’t a good idea until we can take most of the operation and navigation out of the driver’s hands. And that’s the good news here in the real 2015 – driverless cars are edging ever-closer to practical reality. Give me a car that operates itself, and then I’ll start clamoring for it to fly.
New to Hallowe’en in Greenfield Village this year is the Top Hat Side Show. Led by Andrew D'Ascenzo, a professional circus and fire performer, the vaudeville-style show features unique acts in several fields including circus, fire, sideshow, magic, and comedy. Vaudeville performances aren’t new to The Henry Ford; every summer in Greenfield Village our dramatic programs in Town Hall combine music, comedy, and dance revues that pay homage to the great music and zany humor found in vaudeville.
Today organizations across the country are honoring manufacturing with Manufacturing Day, a day celebrating modern manufacturing. There are more than 2,000 events to choose from. We tell the story of manufacturing through our Ford Rouge Factory Tour experience and the artifacts within our collections. If you're curious to learn more about Henry Ford and manufacturing, take a look at this collection of blog posts and videos.
In a typical day at The Henry Ford I find myself answering patron questions or assisting with research. Then, there’s the not-so-typical day when I’m coordinating and work on the Special Access team.
July 13, 2015, was one of those not-so-typical days. I found myself face to face with someone people may call one of the most fascinating inventors in history, Nikola Tesla. You might be asking, how does one find herself in this position? Well, let me show you.
The Special Access Program is designed to allow for closer examination of artifacts in storage, access to artifacts beyond visitor barriers, or filming behind the scenes at The Henry Ford. It allows patrons (film crews, enthusiasts, model makers, etc.) access to our collections that can’t be accommodated in the usual ways such as viewing exhibits and items on display, searching collections online, or viewing material in the public reading room.
In fact, the artifacts from the collection are some of the biggest stars of our television show, The Henry Ford’s Innovation Nation, so the Special Access team is very busy during filming. The first episode of season 2 – filmed in part on this day in July – features the work of Nikola Tesla. I brought several objects to “center stage” for the shoot, including the death mask of Nikola Tesla, shown above. I worked with our Exhibits team to move the electroplated copper mask and its beautifully designed pedestal (which together weigh more than 50 pounds!) from a case in the Made in America exhibition to a sturdy table. It joined several objects that I had moved temporarily from collections storage to the museum for filming:
Race car driver, commentator, author, motivational speaker. Competed in seven Indianapolis 500 races in nine years, including six consecutive years. Two-time competitor in the 24 Hours of Le Mans, the world’s oldest endurance sports car race. Nine-time participant in the 12 Hours of Sebring race. Two wins at the 24 Hours of Daytona race. Owner of over 30 national and international speed records over a 20-year period. A courageous, determined, hardworking, record-breaking, and inspirational race car driver. A woman.
Are you surprised? We're describing Lyn St. James, one of the most influential female race car drivers in history. From her first professional race in 1973, to her last in 2000, Lyn St. James continually showed the motor sports world that not only could women compete with men on the race track, but that they would outlast them, outsmart them, and outrun them. Lyn St. James was a pioneer who embodies the saying that sometimes “it takes a woman to do a man’s job.”
Throughout her career, Lyn helped other female athletes build successful careers just like she had. She serviced as the President of the Women’s Sports Foundation for 3 years, and established her own charitable foundation, Women in the Winner’s Circle, in 1994. Her work with the foundation even led to the formation of a traveling museum exhibit about female drivers, created with The Henry Ford, in 2010.
It is fascinating to connect with objects that were a part of Abraham Lincoln’s world. The Henry Ford owns a number of furnishings from Abraham and Mary Lincoln’s home in Springfield, Illinois, where they lived before Lincoln was elected president.
The Lincoln furniture from their Springfield home tells us about the tastes of the Lincolns in the decades before Lincoln’s election to the presidency in 1860. Stylistically, the furniture represents the middle-class, early Victorian aesthetic of the 1840s and early 1850s. The Lincolns selected sturdy and comfortable, yet stylish furnishings for their home.
