George Washington Carver (c. 1864
[1] – January 5, 1943) was an American
agricultural scientist and inventor who promoted alternative crops to cotton and methods to prevent
soil depletion.
[2] He was the most prominent black scientist of the early 20th century. While a professor at
Tuskegee Institute, Carver developed techniques to improve soils depleted by repeated plantings of cotton. He wanted poor farmers to grow other crops, such as
peanuts and
sweet potatoes, as a source of their own food and to improve their quality of life. The most popular of his 44 practical bulletins for farmers contained 105 food recipes using peanuts.
