Lucius Sawyer Blake (March 14, 1816 – November 4, 1894) was an American carpenter, businessman, and Wisconsin pioneer.

He had little education in his childhood, and worked as an assistant in his father's shops, following him from Vermont to Erie County, New York, and then apprenticed as a carpenter and joiner.

[1] About 1834, the family started moving west by wagon, settling briefly in Michigan and Chicago, before making a claim on 600 acres of land in the area that is now Caledonia, Wisconsin.

After working for a short time employed by Samuel Hale and John Bullen for construction of buildings in Kenosha, he came to Racine and opened his own carpentry shop in 1839.

[2] In this era before the invention of threshing machines, Blake's main work product was manual fanning mills for the grain farmers of Racine County.

As a Democrat, he was a member of Racine's village board in 1844, and then served as county treasurer in 1845, following his father's term in that office.

[1] Two of Lucius' brothers, Edward and Levi, served as officers in the Union Army during the American Civil War.

[1] In addition to his business and political pursuits, Blake was a deacon and member of the board of trustees of the First Baptist Church of Racine.
