In 1891, he was accepted at IOWA agriculture college. he was the only black student at the college,and as usual he supported himself by doing small jobs. he amazed everyone with his special work with plants.after he graduated,
the college asked him to stay on as an instructor because his work with plants and chemistry was so outstanding. so carver stayed on and taught, but he continued his research with plants while he was teaching.
one day he received a letter from booker T.Washington,who was the most respected black educator in the country. Washington asked him to work at the Tuskegee Institute, a black agricultural school in alabama. tuskegee was a poor black school that could not give carver a laboratory or a high salary, but carver decided to go there.
In 1896, carver started to teach and do research with plants at the Tuskegee Institute. He taught classes on agriculture, and through his experiments he found new ways to help the poor, struggling farmers of the south. here, farmers had been growing cotton, which wore out the soil. he showed farmers how to plant different crops like peanuts to make the soil richer. after a while, farmers did what he said and were growing more and more peanuts. they were now making more money from peanuts than from cotton.
carver developed many uses for the peanut. In fact, he found more than 300 uses for the peanut, and he became known as the "peanutman." he received many prizes and awards for his work. He gave lectures about the uses of peanuts all over the united states and even spoke to congress about peanuts in 1921.meanwhile,carver began to experiment with the sweet potato and discovered more than 100 products that could be made from it, including glue for postage stamps.
