Born in Cresco, Iowa (March 25, 1914 -- Sept. 12, 2009), Norman Borlaug was an agricultural researcher, plant pathologist, and plant geneticist. After receiving his doctorate at the University of Minnesota, Borlaug developed genetic varieties of wheat which are highly disease-resistant and are of especially high yield. His work led to staggering increases in the production of agricultural products which, by some estimations, has saved upwards of a billion people who would otherwise die of starvation. He won a Nobel Peace Prize in 1970 for his contributions to humanity.
Rosa Parks represents the “civil rights” category, and is remembered for being a Civil Rights Activists. Her refusal to surrender her seat to a white passenger on a Montgomery, Alabama bus spurred a city-wide boycott. The city of Montgomery had no choice but to lift the law requiring segregation on public buses.
