After the football season, Bieberstein graduated from the
University of Wisconsin Law School and was then admitted to the bar in February 1927. Later that year, he joined the law firm Bull and Biart, which was then renamed to Bull, Biart and Bieberstein. Bieberstein returned to Wisconsin as freshman line coach in 1928 and also served as an assistant football coach in 1931. In 1932, he was an unsuccessful candidate for the
Wisconsin State Assembly, defeated by
Francis Lamb with 8,693 votes, compared to Lamb's 13,118. The following year, he was appointed by the Wisconsin governor to the state bureau of personnel, before being named examiner for the public service commission in 1934. Towards the end of 1934, Bieberstein was appointed
special counsel and was involved in a dispute between Michigan and Wisconsin regarding the states' border. According to the
Kenosha News, "the two states had disputed the location of the boundary line from the
Menominee river to the center of the bay. Wisconsin sought a triangular area between the river mouth and
Chambers Island, while Michigan contended the boundary line should run directly east to the center of the bay". Bieberstein argued his state's case before the
Supreme Court of the United States in
Wisconsin v. Michigan. Eventually, Wisconsin conceded "area in the vicinity of the river". He later was a member of Bieberstein, Cooper, Bruemmer, Hanson and Tinglum. Bieberstein was a member of the
Fraternal Order of Eagles and served as the organization's Madison president. He served on the Belleville State Bank board of directors, was president of the Madison Club, and served as president of the Dane County Bar Association. Bieberstein was married to Amine Bieberstein, having two children with her before their divorce in 1936. He remarried to Merle Klug in 1937. He died on December 31, 1981, in Madison, at the age of 79. ==References==
