George Washington Carver

Contribution. As head of agriculture at Tuskegee Institute from 1896, he taught poor Southern farmers, many of them Black sharecroppers, to restore soil exhausted by cotton through crop rotation with peanuts and other legumes, composting, and diverse food crops. He spread this work through 44 farm bulletins and a mobile school, the Jesup wagon.

Barriers faced

Factors	Statement
Societal Social	He was born enslaved in Diamond Grove, Missouri, and was kidnapped as an infant with his mother.
Educational	His early schooling was limited. His first school, for Black children in Neosho, had a teacher who knew little more than he did, and he moved through several schools in Kansas.
Societal Educational	Highland College in Kansas accepted him and then turned him away because of his race.
Economic	He supported himself at Simpson College in 1890 and 1891 by running a laundry.
Economic Societal	Many of the farmers he served were tenants too poor to buy fertilizer or equipment, and since they could be evicted, they had little reason to invest in the land.

What helped

Factors	Statement
Social	His former enslavers. Moses and Susan Carver, who had owned his mother, raised him after the kidnapping and Emancipation.
Educational Social	A college that accepted him. Simpson College in Iowa admitted him in 1890 after Highland had turned him away. He moved on to Iowa State in 1891, earned a bachelor's degree in agriculture in 1894 and a master's degree in 1896, and was its first Black student and first Black faculty member.
Social Educational	Booker T. Washington. Washington invited him to lead agriculture at Tuskegee, where he began in October 1896.
Economic Societal	Philanthropy and federal support. Morris K. Jesup funded the 1906 wagon, which carried seed from the U.S. Department of Agriculture and reached about 2,000 people a month in its first summer.

Not overcome

Factors	Statement
Economic Societal	The tenancy system and his farmers' poverty limited how widely his methods were adopted. His three patents, for a cosmetic and for paints and stains, were not commercially successful.

Notes

Factors	Statement
none	Carver did not invent peanut butter, and the often-repeated claim of 300 peanut products is inflated. The Carver Museum at Tuskegee credits 287 uses, and historians have found that many were not original. Historian Mark Hersey argues that his lasting contribution was his conservation and environmental thinking, not his peanut products. His 1921 testimony to the House Ways and Means Committee on a peanut tariff made him widely known.
