American biologist and humanitarian whose work producing and promoting hardier strains of cereal crops to give food to more people earned him the 1970 Nobel Tranquility Prize. His launch from the Green Trend also gained him the Congressional Silver Medal. He became a member of the Rockefeller base in 1944 to focus on methods to cultivate whole wheat in Mexico, a issue that occupied him for another 16 years. His brand-new strains of vegetation were presented to great achievement in developing countries like Pakistan, India and Mexico, where they kept millions from hunger. He was raised in a little farming city in Iowa, his family members increasing both cattle and vegetation. Madame Curie, who uncovered the radioactivity of polonium and radium, also gained the Nobel Serenity Prize for assisting to save countless lives.
