Fred C. Haack (c.1873-1944) was the first member of the Social Democratic Party to hold public office in the United States. He was originally elected to the common council of Sheboygan, Wisconsin as a member of the Populist Party in 1897, but he soon joined in organizing the local Social Democratic Party. Running on the Socialist ticket, he was re-elected 5th ward alderman in 1898. He served a total of sixteen years. Haack was recognized as the first American Socialist officeholder at the national Socialist Party convention held in Milwaukee in 1932, despite the fact that socialists had been elected as Chicago aldermen and Illinois legislators as early as 1878. Also elected in 1898 on the Socialist ticket was local baseball manager August L. Mohr.
