William F. Quick, Sr., (July 31, 1885 – December 12, 1966) was an American machinist,[1] lawyer, and Socialist politician in Milwaukee, Wisconsin.

He is not to be confused with William F. Quick (born 1909) who served two terms as Sergeant at Arms of the Wisconsin State Assembly in the 1970s.

[3] Quick had never held public office before the November 1922 general election, in which he was elected to succeed fellow Socialist Louis A. Arnold in the 7th District (the 5th, 12th and 17th Wards of the City of Milwaukee, the Cities of Cudahy and South Milwaukee and the Towns of Lake and Oak Creek) with 5,823 votes, defeating Republican John S. Kanney (who polled 5,531 votes), with 747 votes for Democrat Albert A. Ullenberg.

[4] In 1924 he was the Socialist candidate for Governor of Wisconsin, coming in third in a seven-way race with 5.68% of the vote, to Republican John J. Blaine's 51.76% and Democrat Martin L. Lueck's 39.87%.

[9] In the September 1942 primary elections, Quick and his son William F. Quick, Jr., each got five write-in votes for Socialist city central committeeman from the 27th Ward; and William, Sr., got one vote as Socialist Wisconsin State Assembly nominee from the 17th Assembly district.
