WILLIAM G. THOMPSON was born in Lancaster. Pennsylvania, July 23, 1842. His father was a lawyer in that city. Mr. Thompson was educated at Amherst College, Massachusetts. In 1861, at the age of nineteen, he enlisted in the Fourth Pennsylvania Cavalry for three months. When his term of enlistment expired he removed to Toledo at his mother's request, who imagined that he would have less chance of contracting the war fever in a western city. But when Colonel Arthur Rankin organized a lancer regiment he came here, received a commission as First Lieutenant, and spent the winter of 1861-62 in Detroit. The lancer regiment was disbanded and he went back to Lancaster, and was subsequently appointed an aide-de-camp with the rank of Second Lieutenant in the Sixth New Jersey Infantry. He was severely wounded at Chancellorsville and won his grade as First Lieutenant by gallantry on the field. When his regiment was mustered out in 1864 he studied law in New York for a lime, and then came to Detroit and entered the law office of D. B. & H. M. Duffield. In 1867 he was admitted to the bar and in the same year he married Adelaide Mary Brush, daughter of the late E. A. Brush. Mrs. Thompson died in 1875 leaving one daughter. In November, 1878 Mr. Thompson married Addie Campau daughter of the late D. J. Campau. He served as one of the first Board of Estimates in 1873, as Alderman of the Third Ward in 1874 and 1875, and as Mayor of the city from 1880 to 1884.
