George Washington Carver
Botanist
African-American scientist who became their for his research into and promotion of alternative crops to cotton, such as peanuts, soybeans and sweet potatoes. The destruction of cotton crops by boll weevils inspired his scientific work, and he developed and promoted about 100 products made from peanuts that were useful for the house and farm, including cosmetics, dyes, paints, plastics, gasoline, and nitroglycerin.
He was born into slavery and was kidnapped along with his mother and sister from his master's house in Arkansas when he was just a week old and was sold in Kentucky.
He met with three American president - Theodore Roosevelt, Calvin Coolidge and Franklin Roosevelt - which was very rare for an African-American man at the time. His exact date of birth is unknown with experts primarily placing it in January or June of 1864.
At age 40, he began a relationship with Miss Sarah L. Hunt, an elementary school teacher, but they never married.
Theodore Roosevelt complimented his inventions.
