Kenneth Roy De Groot (October 16, 1929 – April 22, 1993) was an American politician who sat in the Iowa House of Representatives between 1979 and 1993 as a member of the Republican Party. He held the District 1 seat until 1983, when he began representing District 8.
De Groot was born in Perkins, Iowa on October 16, 1929. He was a graduate of Hull High School, and pursued tertiary education at Iowa State University and Northwestern College. After college, De Groot became a dairy farmer for 42 years. Alongside his sons, De Groot owned and operated DG Valley-View Farms. De Groot held membership and executive positions in several agricultural collectives, companies, and associations, among them, 4-H, the Dairy Herd Improvement Association, the Land O'Lakes Northwest Iowa Dairy Division, and the Farm Bureau.[1] [2]
De Groot moved to Doon in 1978, and served in the Iowa House of Representatives between 1979 and 1993 as a member of the Republican Party. He held the District 1 seat until 1983, when he began representing District 8.[1]
De Groot died on April 22, 1993, months after completing his seventh and final term in office. A lung cancer diagnosis in late 1991 influenced his decision to retire from the Iowa General Assembly. He was additionally diagnosed with brain cancer in early 1993.[1]
