Charles Edward Estabrook (October 31, 1847 – December 3, 1918)[1][2] was an American educator, lawyer, eugenicist, and Republican politician from the U.S. state of Wisconsin.

Charles worked on his father's farm throughout his childhood, attending the rural public school during the winter months.

[4] At the outbreak of the American Civil War, Charles was just 13 years old, but was enthusiastic about the Union cause and wanted to join the fight.

[5] He ultimately was allowed to enlist in the third year of the war, in August 1864, and was assigned to Company B in the newly raised 43rd Wisconsin Infantry Regiment.

The regiment was assigned to Tennessee to defend railroad and supply lines, and saw some combat during the Franklin–Nashville Campaign near the end of the war.

[8] Estabrook was a delegate to the 1884 Republican National Convention in Chicago, and in the same year was narrowly re-elected to his old seat, with 1,219 votes to 1,215 for Democrat George Franz.

In 1893, he was one of the principal instigators of a lawsuit to invalidate the redistricting act which had been passed by the Wisconsin Legislature in 1891.

He was elected to the Assembly from the 13th Milwaukee County district (the 13th Ward of the City of Milwaukee) in 1906 to succeed fellow Republican Henry Holle, with 1,224 votes to 905 for Socialist Henry Leetzen and 593 for Democrat Frank Gerski; he was assigned to the committee on cities (of which he was made chairman) and the joint committee on forestry.

Edward Estabrook was a native of Illinois and became an early settler of Grant County after the land was acquired from the Meskwaki, establishing his farm near Platteville in 1836.
