Isaac Brown (June 4, 1811 – 1883) was an American construction contractor, Democratic politician, and Wisconsin pioneer.
His former home, the Fond du Lac Octagon House, is listed in the National Register of Historic Places.
Their son, Edwin Arnold Brown, served as a Union Army officer in the American Civil War.
Edwin Brown was killed in the early hours of the Battle of Antietam when a shell fell directly into the ranks of the regiment.
The home still exists at 276 Linden Street in Fond du Lac, and is now listed on the National Register of Historic Places.
