Franz Chadbourne Eschweiler (September 6, 1863 - November 14, 1929) was an American lawyer and judge from Wisconsin. He was a justice of the Wisconsin Supreme Court for the last 13 years of his life. He previously served five and a half years as a Wisconsin circuit court judge in Milwaukee County.
Born in Houghton, Michigan, Eschweiler studied at the University of Michigan and the University of Iowa. Eschweiler was admitted to the bar in Milwaukee, Wisconsin, in 1889, and practiced law, in Milwaukee. In 1910, he was elected a Wisconsin Circuit Court judge for the newly created 6th Branch of the Milwaukee County-based 2nd Circuit. Rather than running for re-election in 1916, he ran for a seat on the Wisconsin Supreme Court, set to be vacated by the pending retirement of justice William H. Timlin. Eschweiler won the spring 1916 election, and was appointed to begin his term early - in August 1916 - following Timlin's death. Eschweiler ultimately served on the Wisconsin Supreme Court until his own death in 1929.[1] [2]
