George Shull, the father of hybrid corn and agricultural innovation

Today newspapers announced the retirement of the "father of hybrid corn," George Shull.
An Ohio farm kid, George was a noted botanist who taught at Princeton University for 27 years.
George's work resulted in a one hundred and fifty million-dollar increase in the value of US corn as a result of his crossing pure line varieties with self-fertilized corn. George's uber-productive hybrid yielded ten to forty percent more than ordinary corn.
Like many plant breeders, George never made a penny from his creation.
