Booker Taliaferro Washington (April 5, 1856 – November 14, 1915) was an African-American educator, author, orator, and advisor to presidents of the United States. Between 1890 and 1915, Washington was the dominant leader in the African-American community. More on http://en.wikipedia.org/wiki/Booker_T._Washington

George Washington Carver (c. 1860 – 5 January 1943), was an American botanist and inventor.
Carver's reputation is based on his research into and promotion of alternative crops to cotton, such as peanuts, soybeans, and sweet potatoes, which also aided nutrition for farm families. He wanted poor farmers to grow alternative crops both as a source of their own food and as a source of other products to improve their quality of life. The most popular of his 44 practical bulletins for farmers contained 105 food recipes using peanuts. More on https://en.wikipedia.org/wiki/George_Washington_Carver
