Like Carver, Borlaug grew up in a tiny farm town in the Midwest—in Cresco, Iowa.
By the early 1960s, Mexico was growing six times more wheat than it did when Borlaug first arrived.
Borlaug studied forestry, and then obtained a Ph.D. in plant pathology.
Borlaug and his associates set out to develop strains of wheat that could resist diseases and pests, and thus improve yields.
Next, Borlaug helped develop more productive and drought-resistant strains of rice that became adapted widely in Asia.
Like Carver, Borlaug then sought to institutionalize his breakthroughs.
