As a young man, Beilfuss was involved in local highway safety efforts after the death of his brother, Wayne, in a 1935 car accident.
[5] He entered politics in 1940, challenging incumbent village president Charles Hoffman for his seat on the county board.
[6] Later that year, Beilfuss entered the race for district attorney, challenging the incumbent, Hugh F. Gwin, in the Wisconsin Progressive Party primary election.
Beilfuss hired Milwaukee detective Otis Gomillion to come to Clark County to solve the string of crimes.
Six members of the gang were eventually arrested, confessing to 11 robberies, with stolen property valued at about $4000 (about $86,000 adjusted for inflation to 2024).
[10] The next year, Beilfuss brought charges of forgery and embezzlement against the Clark County coronoer, P. C. Ludovic, who pleaded guilty in April 1942.
[11] After the outbreak of World War II, Beilfuss enrolled in the United States Navy Reserve, and he was called up for active duty in August 1943.
[13] He was initially sent to Naval Station Great Lakes for induction and was commissioned an ensign; he was then ordered to Norfolk, Virginia, in January 1944, for further training.
[15] Beilfuss was subsequently deployed to the Philippine-Japan region and served through nearly all of 1945 as a PT boat captain, screening for Pacific Fleet aircraft carriers.
[19] A week after the election, Governor Oscar Rennebohm appointed Beilfuss to begin his term in office early, as the seat was already vacant.
[25] A few months after the Jantz case, Beilfuss announced his candidacy for Wisconsin Supreme Court, seeking the seat being vacated by the expected retirement of chief justice Timothy Brown.
[30] Beaudry had used the election as a platform to advocate for probate reform, no-fault auto insurance, and greater state supervision of the courts.
[1] Bonnie Bielfuss also volunteered for service in World War II and served as a medical dietician in the Army and achieved the rank of first lieutenant.
[39][40] Seventeen months after his first wife's death, on October 17, 1961, Beilfuss married De Ette Helen Knowlton, of Ellsworth.
He served as chair on the Board of Visitors of the University of Wisconsin Law School, was a member of the Veterans of Foreign Wars, the American Legion and a founder of the Dane County Big Brothers program.
