David Sigman (1905 – February 1, 1987)[1] was an American trade union staff member from Two Rivers, Wisconsin who served three terms as a Republican, then a Progressive member of the Wisconsin State Assembly from the 2nd Manitowoc County district.
He was still in law school when first elected to the Assembly in 1930 from the 2nd District (the Towns of Cato, Cooperstown, Eaton, Franklin, Gibson, Kossuth, Maple Grove, Mishicot, Rockland, Schleswig, Two Creeks, and Two Rivers; Villages of Reedsville and Valders; and the Cities of Kiel and Two Rivers) as a self-described "Progressive Republican", with a plurality over three challengers in the Republican primary.
[4] In 1934, Sigman (now working as a union organizer for the Wisconsin State Federation of Labor, part of a WSFL policy of offering employment to key pro-labor legislators to supplement the low legislative salaries) reclaimed his seat, first by winning a three-way Progressive Party primary, then by defeating Democratic and Republican nominees (Scheur was not a candidate for re-election) in the general election.
In 1939, as part of a campaign against perceived supporters of Henry Ohl in the WSFL, Sigman lost his seat on the WSFL executive board, one he had been elected to in 1937 as recognition of his key role in defending labor interests in the just-ended legislative session.
[5] Among the council's other leaders was former Socialist assemblyman John Polakowski; at one point he was their president.
