1921 Congresswoman Alice Mary Robertson becomes the first woman to preside over the floor of US House of Representatives

Oklahoman Alice Mary Robertson, seen here outside the Capitol Building, was elected to the House in 1920. She served on the Indian Affairs Committee; the Committee on Expenditures; and, as the only woman in the House, she was appointed to the Committee on Woman’s Suffrage. Although she was the first woman to preside over a House session, Robertson was, ironically, also opposed to women seeking national political office.
