This election win gave Representative Rankin the distinction of being the first woman elected to serve in Congress.1 The first woman to serve in the Senate was Rebecca Latimer Felton (D-GA). She was appointed in 1922 and served for one day. [...] This report includes brief biographical information, committee assignments, dates of service, listings by Congress and state, and (for Representatives) congressional districts of the 327 women who have been elected or appointed to Congress.
