Wisconsin has been active on the national chess scene for longer than most other states in the union, but we seem to have come to the idea of formalizing the state champion later than our contemporaries. The earliest formal championship we've been able to find was a match that crowned Carl Eppert as the official state champion. We're still digging through archives looking to fill in the blanks, as there was active club play in the state going back to the days of Morphy and Paulsen. This list is the official list; if you have information about champions not on it, please contact us with the information.
