Jeannette Rankin (1880-1973), the eldest child of a prominent family in Missoula, Montana, was the first female in American history to be elected to federal office. Running as a Republican (which was then considered the ‘cleaner’ party in her state), she represented Montana in two non-consecutive Congressional terms, from 1917-19 and again from 1941-43. She was Progressive, a leading Suffragette, a supporter of worker’s rights and a devout Pacifist. However, she is particularly remembered for her votes against Declarations of War both on April 6th, 1917 and on December 8th, 1941. You can read more about her by clicking on this link.
