A farmer and inventor, Edward Gideon “E.G.” Melroe founded Melroe Manufacturing Company in Gwinner, North Dakota, in 1947. His notable inventions included the Melroe pickup, a combine attachment that would pick up windrows of grain, and the harroweeder, a spring-tooth harrow for weeding row crops. Melroe died in 1955, leaving his sons Lester, Clifford, Roger and Irving, and son-in-law Eugene Dahl, in charge of the business. The prosperous farm implement business changed course in 1958, after the brothers met with inventors Cyril and Louis Keller, from Rothsay, in western Minnesota.
