On October 1931, he was named the Conservation Commissioner of the state of Ohio. While in this position, he took many steps to improve game wildlife in Ohio, and he spoke to sportsman’s groups all over the state. Mr. Reinhart was one of the founders of the Ohio State Elks Association, and he served as its president twice. During this time, in the late 1930s, Mr. Reinhart also served as a city commissioner.
William H. Reinhart died on December 31, 1940 at the Cleveland Clinic, after a lengthy illness. Funeral services were held at the Sandusky Elks Lodge, with the Rev. C.L. Alspach officiating. He was buried at Sandusky’s Oakland Cemetery. He was survived by a wife, one sister, one brother, a daugher, a stepson, and three grandchildren. The Sandusky city building was closed during Mr. Reinhart’s funeral, and the flag at the Post Office flew at half staff, in memory of the former city leader. George J. Doerzbach, fellow city commissioner, said about Reinhart, “No Sanduskian had the interest of this city more at heart than did Mr. Reinhart. I have worked with him for many years on civic and social affairs and always found him ready to give of his time an energy in helping to boost his home community and give a helping hand to his host of friends."
