179. Harry Stine
The Mcpherson College alum, who is dyslexic and mildly autistic, was the first in his family of farmers to go to college. He put himself through school by washing milk bottles and digging up plants for a nursery. He got into seed breeding in the 1960s and was one of the first to patent the genetics of the soybean in the early 1990s. His firm, which licenses his powerful corn and soybean seed genetics to multinational firms like Monsan to and Syngenta, has over 900 patents on soybean seeds alone.
