Alden Isaac Bennett (August 23, 1807 – June 17, 1862) was an American physician, Republican politician, and Wisconsin pioneer.
In 1859, he was renominated in a contested convention and went on to defeat Democrat Daniel Ruggles Spooner in the general election, earning another two years in the Senate.
Two of their sons, Phineas and Thomas, served as officers in the Union Army during the American Civil War.
Thomas served as a chief clerk and quartermaster on the staff of General William Tecumseh Sherman.
[2] Phineas Bennett served only a few months, because he was wounded at the Battle of Shiloh shortly after his regiment was mustered.
After hearing of the battle, Alden Bennett went to the Shiloh battlefield, along with Governor Louis P. Harvey and his delegation.
