Farmers have only a narrow window of opportunity to harvest their crops. For Michigan soybean growers, that window generally runs from the end of September through November, but is impacted yearly by weather events. By that point in the season, the plant is fully mature and has lost most of its leaves, and only the stalk and pods (with three to four beans per pod) stand in the field (R8 Growth Stage). The seeds are brown and hard at this point, and bean moisture content is 13-15%.

Harvesting soybeans—to cut the stalk, separate the bean from the pod, clean the bean, and store it until moved from harvester to wagon or truck—requires a multifunctional machine. Soybean growers benefitted from around a century of experimentation with specialized harvest machines when it came time for them to look for the best machine for the job. Farmers need machines that work, and different machines to harvest different crops. The Henry Ford has some of the earliest of these mechanical innovations, each suited to a specific crop—the Ambler mowing machine for hay, models of the Hussey and McCormick reapers for grains, and the Manny combined mower and reaper (one machine adaptable for both crops).
These early-19th-century innovations represented solutions to the problem of how to reduce human labor costs. Farm families often could not meet labor demand during harvest seasons. Too little labor meant lost crops, and lost crops made it difficult for farmers to feed their livestock (hay) or earn income from market crops (grain). Hiring labor was expensive, and even more expensive during peak demand at harvest time.
A century passed between the 1830s, when mechanical reapers and mowing machines first became viable, and the 1930s, when the first Allis-Chalmers All-Crop Harvester entered Michigan soybean fields.

Michigan growers raised different types of beans during the early 20th century. Some raised bush beans (Phaseolus vulgaris), green beans that they harvested by hand when the pod reached the R5 growth stage and seeds had just begun to develop. Wholesale dealers distributed this perishable commodity to grocery stores while processors turned the bush beans into canned green beans. Others raised large fields of beans on contract with the H.J. Heinz Co. After the beans were fully matured and dry, growers harvested the crop by hand, then hauled the crop to a threshing machine that separated the beans from the pods and stems. Employees at Heinz processing plants continued the handwork, sorting beans from debris. Product advertising emphasized this attention to detail that yielded a quality food product.
A different type of bean—the “soy bean” (or soybean, Glycine max)—became increasingly apparent in southeast Michigan during the 1930s. Interest in this new cash crop grew apace with Henry Ford’s investment in soybean research. Scientists at work in the chemical laboratory that Ford built in Greenfield Village confirmed that soybeans had potential as a domestic source for various industrial products. Industrial demand in the region caused growers to seek a harvester suitable to the task.

Some farmers raised seed crops to meet growing demand for the new cash crop. This specialized cultivation required careful harvesting, as described in “Soy Bean Seed Production in Michigan” (1936). Others raised crops to meet the growing demand for the new industrial raw material. The Ford Village Industries complex in Saline, Michigan, opened in 1938. A press release issued by Ford Motor Company in July 1938 indicated that 700 farmers planted 22,588 acres of soybeans processed at the Saline facility. Ford processing capacity increased as the soybean processing plant at the Rouge Plant began operations around 1942.
Ready for the Harvest: The Allis-Chambers All-Crop
Farmers needed mechanical harvesters to ensure that they delivered a prime crop to Ford Motor Company. Henry Ford thus took an interest in this technology. Allis-Chalmers released its All-Crop 60 harvester in 1935, designed to operate off a tractor big enough to pull a double-bottom plow and powered by the tractor’s power take-off. The “60” represented the width in inches of the swath cut by the harvester. Ford tested the capability of the Allis-Chalmers All-Crop Harvester on a Ford Farms soybean crop in October 1936. By that time, Allis-Chalmers had sold 8,200 of the machines.
The engineer who took a leading role in the machine’s development was Charles J. Scranton, Jr. He began his career as a draftsman at Avery Company, a Peoria, Illinois, company noted for steam traction engines, threshers, and other farm equipment that went bankrupt in 1923. Scranton, as an assignee to a successor company, the Avery Power Machinery Co., secured several patents for improvements to threshers during the late 1920s.
Scranton joined Allis-Chalmers by working at the LaPorte, Indiana, location by 1934. Over 30 years, he secured around 40 patents, all focused on harvesting machinery. The All-Crop marked a crowning achievement because it suited the needs of farmers operating on a smaller scale and growing different cash crops, including soybeans, clover, milo, and other grains.
Ford featured the Allis-Chalmers All-Crop Harvester in early promotional photographs of the Ford tractor with the “Ferguson System,” the Ford-Ferguson 9N, released in 1939. This marked a ringing endorsement from the industrialist who launched soybeans as a cash crop in Michigan.

More Crop in the Hopper
As soybean acreage increased across the Midwest after World War II, farm implement companies continued to innovate. The Allis-Chalmers All-Crop was well suited to smaller scale farmers growing a variety of crops, but the scale of production increased dramatically during the 1950s as farmers in the midwestern Corn Belt shifted toward monoculture, e.g., corn, a crop heavily dependent on nitrogen, and soybeans, a legume that helps retain nitrogen in the soil. Farmers saw this combination as a strategy to help reduce input costs for synthetic and nitrogen-rich fertilizers.
Illinois-based agricultural implement manufacturer Deere & Company gained an advantage in 1954 when the company introduced an attachment that farmers could install on their combine harvesters to harvest corn. They could harvest their bean crop by switching out that attachment with a four- or five-bat (or horizontal bar) reel mechanism that drew the bean crop into the cutting head. Interchangeable front-end attachments became an industry standard.

The New Holland TR70 Axial Flow combine in Henry Ford Museum of American Innovation is installed with the corn harvester attachment. Farmers could harvest four rows of corn in one pass through the field with this head. To harvest soybeans, they installed a different attachment to the front end, a “pickup reel,” as illustrated below in a New Holland TR70 product catalog. The promotional literature urged farmers to purchase a floating “cutterbar” and a “robot header height control” to harvest most efficiently.

Soybean acreage increased rapidly from the late 1970s into the 1980s. This sustained research in and development of combines suitable to cutting, threshing, and cleaning soybean crops (along with corn and other smaller grains).

A New Partnership
Today, on National Agriculture Day, The Henry Ford is pleased to announce a new partnership with the Michigan Soybean Committee to deepen our understanding of this important crop, from field to factory.
The Michigan Soybean Committee works on behalf of Michigan’s 12,000 soybean farmers to drive demand, fund research advancements, share the story of agriculture, and identify ways to help farmers grow soybeans sustainably for generations to come. Michigan Soybean Committee has a renewed focus on consumer outreach and working with partners to provide information to the public about soybeans and agriculture in the state of Michigan. The collections of The Henry Ford help tell the long history of soy, and especially the launch of the legume in Michigan, a project with a long history dating back to Henry Ford himself. Michigan Soybean Committee is excited to work with The Henry Ford to provide the public with the chance to learn more about agriculture and the innovations that have helped farmers feed the world.
The soybean (soya bean, Glycine max) moved from relatively obscure forage crop in 1920 to center stage on global markets in 2020. Today soybean farmers in 19 states, including Michigan, raise 96% of the more than 4 billion bushels of beans produced in the United States. Each of those soybeans contains oil, protein, and biomass, attributes that processors use to transform the soybean into valuable products.

Today we encounter soybeans in almost every aspect of our daily lives, but we may not recognize the legume, even when we use or consume it. Drink soymilk? Use a non-dairy creamer or whipped topping? Eat chocolate? Use soy oil for cooking? Is your candle made of soy? How about the bioplastic coating your take-out food container or disposable coffee cup? Have you ever filled your vehicle with biodiesel? These products, and many more, likely include ingredients derived from soybeans. The Michigan Soybean Committee recommends the United Soybean Board website https://soynewuses.org/ as a good resource to learn even more about all of the products made with soy.

Black chemists contributed to this soybean research. Paul Foster focused on food research. “Paul Foster and Food Research in Henry Ford’s Laboratories, 1930-1942” introduces readers to Foster and explores some of the soy recipes that resulted from research he conducted. George Washington Carver and his assistant, Austin Curtis, Jr., chemists working at Tuskegee Institute in Alabama, shared Henry Ford’s enthusiasm for chemurgy (industrial uses for raw materials). Both Carver and Curtis participated in the third Dearborn Conference on Industry in 1937, featuring lectures by chemists working with farm-grown crops and industrial products, and Curtis even worked one summer in Ford’s Greenfield Village Soybean Lab. Ford expanded soy food research in 1942 with dedication of the Carver Nutrition Laboratory on Michigan Avenue in Dearborn, near Greenfield Village.

What do we have in store for this partnership?
We’ll kick things off on March 23 on The Henry Ford’s Facebook page, with an interview with Laurie Isley, Michigan farmer and president of Michigan Soybean Committee. You can get a sneak peek of Isley’s work at the websites for U.S. Soy and the Michigan Agriculture Council.

Our plans for 2022 focus on exploring untold stories, adding to existing stories, and engaging the public in the process. We will explore changes in biological and mechanical technologies between 1920 and 2020, and document agricultural research at Ford farms focused on producing soybeans richer in oil content and better suited to industrial uses. We will deepen existing content on the daily operations of soybean research undertaken at the chemical laboratory constructed by Henry Ford in Greenfield Village in 1928 (still standing today), and in the George Washington Carver Nutrition Laboratory launched by Ford in 1942.
Over the growing season, we’ll explore the year-round work it takes to produce soybeans in Michigan, from planting to growing to harvesting, with the farmers who do this work. This will also involve a collaborative contemporary collecting effort to document Michigan soybean farmers today and add those stories to the permanent collections of The Henry Ford.

The Michigan Soybean Committee will share its popular teacher resources with The Henry Ford’s learning and engagement staff. This will benefit rising fifth graders in The Henry Ford’s 2022 Growers summer camp, presented by the Michigan Soybean Committee, as they explore soya from bean to bioplastic. From June to August, students in the Growers summer camp will interact directly with Michigan Soybean Committee resources and soybeans growing in Greenfield Village for the first time since the 1940s.

The Soybean Laboratory (now the Soybean Lab Agricultural Gallery) in Greenfield Village buzzed with activity during the 1930s and 1940s. Paul Hunter Foster worked as a waiter in that laboratory in its earliest days, but over time, his responsibilities expanded to include valet to Henry Ford and cook on Henry Ford’s private railroad car, Fair Lane. As these photographs indicate, he tested soy foods and may have fed the laboratory staff in the process.
Paul Hunter Foster was born on June 5, 1900, to a well-connected mixed-race family living in Meridian, Mississippi. His father, William Thomas Foster, sampled cotton and rated bales based on cotton quality. His mother, Alvina (“Vinie”/“Viny”) Lewis Hunter, bore seven and raised five children. Most of them pursued higher education and community service and flourished professionally. Three studied at Tougaloo College in Jackson, Mississippi. One graduated from Fisk University in Nashville, Tennessee, and another from Howard University in Washington, D.C. Two of Paul’s brothers became dentists, and another worked in race relations throughout his career.
Piecing together the details of Paul Foster’s life remains a work in progress, but primary sources confirm that he lived in Washington, D.C., after his father died in 1917. One of his brothers lived there at the time, attending Howard University. Paul worked as a messenger for the U.S. War Department during World War I (per his draft registration card). He was back in Meridian in January 1920 (per the U.S. Census). Then, on July 7, 1920, while still a student, he married Lilybel E. Scott in Detroit, and settled into life at 6081 Whitewood Avenue in Detroit.

It remains unclear when Paul Foster joined Henry Ford’s staff, but his work in Greenfield Village and in proximity to Henry Ford’s office at Ford Motor Company’s Oakwood Boulevard headquarters translated into “other duties as assigned.” In 1935, this included escorting a special guest invited to the Stephen Foster Home dedication. A reporter from the Pittsburgh Courier explained on September 21, 1935, that Georgia Singleton Ralls had, as a child, lived in the house in Lawrenceville, Pennsylvania. She provided valuable information about the home interior to Henry Ford via Charles T. Newton. Ford invited her, but the Foster family ensured her personal comfort. She stayed with Paul and Lilybel and their four children during her visit. Ralls described Paul Foster as Henry Ford’s valet.
Detroit newspapers confirm that Paul and Lilybel Foster encouraged education, a love of music and theater, and civic engagement. Lilybel and the four children, Paul H. Foster, Jr., [William] Estus, Jane, and Harris, each received their share of coverage in the Michigan Chronicle social pages. This helped them forge networks with other middle-class Black Detroiters.
In addition, Paul Foster, Sr., developed relationships with other Black Detroiters working in industry. His eldest child, Paul, Jr., listed Bohn Aluminum as his employer on his World War II draft registration card, and his second son, William Estus, listed Ford Motor Company. The elder Foster also listed Ford Motor Company, Oakwood Boulevard, as his employer. The sons listed their mother as the person most likely to know their permanent addresses, but Paul, Sr., listed Frank Davis, a field agent for Detroit Light Company (Detroit Edison Company), instead of his wife. This likely reflected a commitment to class and racial bonds among well-connected Black Detroiters employed in managerial positions by white business owner-operators. Frank Dewitt Davis became the first Black employee in an office position at Detroit Edison according to his obituary (published in the Detroit Free Press, September 19, 1974).
Work in the Soybean Lab
The following provides a snapshot of the chemical laboratory that Henry Ford constructed in Greenfield Village during 1929, and the workspace that Paul Hunter Foster, Sr., occupied.
Henry Ford invested in the chemical laboratory to discover industrial uses of agricultural products. Soybeans, a crop with a long history, became the research focus by 1931. The crop offered much potential. Extracted oil could be refined for multiple uses and the bean residue could be pressed into numerous molded forms. The protein- and oil-rich soybean also addressed the need of many seeking healthier foodstuffs.

Foster worked in the lab that undertook food experiments during this early period of exploration and innovation. His workspace consisted of the low-roofed kitchen shown below, divided by a railing. The preparation area included ingredients, storage containers, scales and other data collection instruments, and scientific apparatuses to facilitate testing.

Staff worked together in this testing kitchen. The photograph below shows Foster at work in the foreground, and another lab technician busy in the background.

The cooking area in the kitchen laboratory included a range, a sink, and counter space, as well as measuring cups, pots, pans, and other kitchen implements. It was at a slightly lower level than the preparation area.

Food testing occurred in this lab. The results appeared in the booklet “Recipes for Soybean Foods.” It described the work of the laboratory, summarized the benefits of soy-based foods, and consolidated recipes proven in this laboratory.
“Recipes for Soybean Foods,” circa 1931. / THF119280a
Cooks had to be aware that preparing soybeans required some extra effort. For example, “the soy bean generally requires a longer time for cooking than does the common bean…. With a pressure cooker, the beans can be cooked in 20 minutes at 20 pounds pressure” (page 2). Paul Foster used a pressure cooker to prepare soybeans in the kitchen workspace.

Soybeans had a higher protein content than navy beans or lima beans, according to “Recipes for Soybean Foods.” Thus, cooks substituted soybeans to facilitate healthy eating.
An omelette, two baked beans recipes, and two salad recipes in “Recipes for Soybean Foods,” circa 1931, page 9. / THF119283b
Soy flour also offered a higher-protein alternative to wheat flour, and a flour more supportive of diabetic diets and other diets for those intolerant to certain foods. Furthermore, soy flour properties helped bread remain fresher for longer. As “Recipes for Soybean Foods” explains, breads that incorporated 5% soy flour and 95% wheat flour produced a loaf of bread that kept longer than bread made without soy flour. Combining flours at a ratio of 20% soy and 80% wheat resulted in a bread loaf with 40% more protein than wheat flour alone (page 2). Such persuasive arguments converted some to soy.
The photographic print below shows Paul Foster preparing dough for soybean bread in the kitchen workspace.

After baking, storing the bread in a wire-enclosed wood-frame container was the next step in the longer process of documenting drying rates for different types of bread loaves.

A closer look at Foster and his bread loaves, in the photo at the very top of this post, shows him in the process of loading the loaves into the food safe (a term used for similar wire-sided storage cabinets). The experiments in the test kitchen continued with rotation of loaves and measuring rates of dryness.
Interested in trying the recipe for the soybean bread baked in the laboratory in Greenfield Village? Check out page 4 of Recipes for Soybean Foods, or explore these and other recipes in the Ford Motor Company bulletin, published around 1939 (and two pages longer). Be mindful of inconsistencies. In both, on page 2, the directions indicate that the pressure cooker should be set at 20 pounds pressure, but page 16 in the earlier booklet, and page 18 in the 1939 version, states that soybeans should be cooked for 20 minutes at 25 pounds.

Foster remained visible in Soybean Laboratory research through the visit of George Washington Carver in July 1942. During this visit, Henry Ford dedicated a nutrition laboratory on Michigan Avenue, adjacent to Greenfield Village, named for Carver. It included an experimental kitchen described as “the dominion of Mr. Paul Foster” (Herald, August 14, 1942, page 12).
George Washington Carver (seated) at the dedication of Carver Nutrition Laboratory, Dearborn, Michigan, July 21, 1942. Paul Foster is standing in the foreground to the right. / THF214097
Foster apparently had full authority over the kitchen in the Carver Nutrition Laboratory: “Here this master of the culinary art will hold forth, concocting delicious morsels” (Herald, page 12). Carver credited Foster with the “weed sandwiches” sampled during the Nutrition Lab dedication (Herald, page 14). Carver appreciated such ingenuity, given his recent bulletin Nature’s Garden for Victory and Peace (March 1942). Foster’s sandwich spread of “nature’s vegetables” consisted of ground dandelion, purslane, curly dock, plantain, chickweed, lamb’s quarters, bergamot, oxalis, and radish seed pods with salt, lemon juice, and mayonnaise added. Served on soybean bread, such a mixture could have a wonderful flavor and “contain the equivalent in vitamins and minerals to the average person’s monthly diet of vegetables.” So explained Edison Institute student Robert Cavanaugh, who reported on “The Development of a New Laboratory” (Herald, page 12). A photograph of Foster, preparing vegetable sandwiches, illustrated the story.
Documenting Paul Foster’s role in research in either laboratory after 1942 remains a work in progress. Consider this a first installment as we continue to learn more about the scientists who worked at the Soybean Laboratory in Greenfield Village, and at the nearby Carver Nutrition Laboratory on Michigan Avenue.

One of The Henry Ford’s main collecting areas is agriculture and the environment. Last fall, Processing Archivist Hilary Severyn shared highlights from our archives around women in agricultural work and research as part of our History Outside the Box program on Instagram. If you missed it, you can check out her selections, which range from women working on soybean research to the Women’s Land Army to Rachel Carson’s fight against pesticides, in the video below.
In the 1920s, following his success with the Model T, Henry Ford increasingly turned his attention to transforming farming—the life he sought to escape as a boy. He focused on finding new products and new markets for agriculture. (The charcoal briquette was an early result of this effort, made from surplus wood scrap.)
In 1928, Ford started the Chemical Lab (the building in Greenfield Village now known as the Soybean Lab), and asked Robert Boyer, a student at the Ford Trade School to run it. Ford told Boyer to select good students from the Trade School to staff the Lab. Ford then set them to experimenting with all manner of agricultural produce, from cantaloupes to rutabagas.
