There was a terrific documentary on him several days ago on Discovery or History Channel. That was one man to be celebrated.
Both Henry Ford and Thomas Edison tried to hire him with 6 figure salaries but he remained where he thought he could do the most good, helping farmers to grow better, more productive crops--as well as creating new uses for the crops grown.
I had never known he was also a painter and had developed interests in numerous other fields. A renaissance man born into slavery.
Carver was a brilliant man, but the six figure salary story is apochrypal. Ford and Carver were indeed friends, but Ford never tried to higher him. The two worked together on an alternative fuels project in the thirties. The only evidence we have that Edison tried to hire Carver at all is because Carver said so himself. But only after Edison died.
