Dennis D. Conway (May 3, 1868 - December 15, 1926) was an American lawyer and politician from Grand Rapids, Wisconsin who was elected 1912 to a single term as a member of the Wisconsin State Assembly from Wood County.
Clark was born May 3, 1868 on a farm in the Town of Rudolph in Wood County. He worked on the farm, in sawmills and in the woods, attending local public schools intermittently when he was not needed for the farm and other work.
He eventually attended the Oshkosh Normal School, and graduated from the Northwestern Business College in Madison. He taught school for three years; graduated from the University of Wisconsin Law School in June 1895; and took up law practice in Grand Rapids in July of that year, specializing in personal injury cases for laborers.
Conway, a Democrat (by 1897 already a member of the Party's State Central Committee), was elected Clerk of the Circuit Court of Wood County in 1890 at the age of twenty-two, and held the office for two terms. He was a member of the county board of supervisors, Grand Rapids city attorney, and county district attorney, and defeated a popular incumbent county superintendent of schools, the only victor on the county's Democratic ticket that year.
