Career
Born in Dumbartonshire, Scotland, McIndoe immigrated to the United States in 1834. He engaged in business in New York, Charleston, and Saint Louis, finally settling in Wisconsin in 1845 where he became involved in the lumber business. During the Civil War he was provost marshal of Wisconsin.
McIndoe was elected as a Republican to represent Wisconsin"s 2nd congressional district in the Thirty-seventh Congress to fill the vacancy caused by the death of Luther Hanchett (January 26, 1863–March 3, 1863).
He was reelected to the Thirty-eighth and Thirty-ninth Congresses this time as the representative of Wisconsin"s newly created 6th district serving from March 4, 1863 to March 3, 1867. During the Thirty-ninth Congress, he served as chairman of the Committee on Revolutionary Pensions.
In 1866, McIndoe declined candidacy for renomination, instead resuming his interests in the lumber business. He died in Wausau, Wisconsin on August 22, 1872 and was interred at Pine Grove Cemetery.
