Bartel John Jonkman (April 28, 1884 – June 13, 1955) was a politician from the U.S. state of Michigan.
Jonkman was born in Grand Rapids, Michigan, where he attended the public schools. He was of Dutch descent.[1] He graduated from the law department of the University of Michigan in 1914, was admitted to the bar the same year, and commenced practice in Grand Rapids. He served as assistant prosecutor of Kent County from 1915 to 1920, and as prosecuting attorney from 1929 to 1936.
the fourth of the Republican Opposition group on the committee. An agreeable man, shrewd, capable and very determined in his opposition to the Administration in both its foreign and domestic policies. Pure Isolationist before Pearl Harbor, and, in fact, typical of the Michigan Republican Bloc (whose most notorious member is Clare Hoffman). Seems convinced America is playing Santa Claus again in this war, and is doing his best to obtain facts and figures which will show up this fact. A Methodist; age 59. Nationalist.
Bartel J. Jonkman had become unpopular largely due to his isolationist position on foreign policy. He resumed the practice of law and died in Grand Rapids. He was interred there in Woodlawn Cemetery.
