In 1896 Carver came to Tuskegee University (then the Tuskegee Institute) at the request of [Booker T. Washington]? and specialized in botany. He became director of agricultural research. Taking an interest in the plight of poor Southern farmers working with depleted soil, he became a promoter of crop-rotation and legume planting, which could restore nutrients to the soil. In order to make this enterprise profitable, he devised numerous uses for such products, including perhaps 300 uses for the peanut ranging from glue to printer's ink. He made similar investigations into uses for other products such as sweet potatos and pecans. He often said that if all other foods were gone from the earth, the peanut and sweet potato alone could provide sufficient food, in both nutrition and in variety of preparation, to sustain humans indefinitely.
George Washington Carver died January 5, 1943. As a legacy, he left behind the Carver Resarch Foundation at Tuskegee, founded in 1940 with his life's savings.
Carver Hall, at Iowa State University, is named after him.
