Roswell Garst's parents were Edward Garst and Bertha Goodwin. He married Elizabeth Henak on January 31, 1921. He was diagnosed with cancer of the voice box in 1963. Garst was founder of Garst & Thomas Co., which became one of the world's largest producers of hybrid seed corn. In the 1930s, Garst traveled around the Midwest convincing farmers of the benefits of hybrid seed corn. As an international agriculturalist, he encouraged modern farming methods to improve food production in many nations, including the Soviet Union, Chile, Hungary, Germany, and France. Garst was famous for offering (sometimes unsolicited) advice. When Khrushchev visited Coon Rapids, Garst could not help but discuss the US-Soviet political situation, and told Khrushchev, `You know, for a peasant, you're a damned poor horse trader.'citation needed Garst made six trips to the Soviet Union to teach about hybrid seed and farm mechanization. He also sent his sons, including David Garst, on similar trips. Garst, in his own view, was not only an agriculturalist, but also a goodwill ambassador promoting peace during the Cold War.citation needed
