Wilder Arthur Simpson (May 22, 1887 – March 31, 1971) was an American politician who served in both houses of the Vermont General Assembly. He ran for governor in 1930, 1932, 1944, and 1960 but was unsuccessful in the Republican primary each time. Known as Vermont's "Mr. Republican," he supported a number of Democratic candidates later in life, including Philip H. Hoff.[1] [2]
Simpson married the former Ruth Hoffman on July 24, 1912. Together they had one son and three daughters.[2]
