Former Indiana Sen. Birch Bayh, the man behind the landmark Title IX legislation, died Thursday morning from pneumonia at the age of 91.

Besides serving in the Senate for three terms, the liberal Democrat was also the father of former Indiana Gov. and Sen. Evan Bayh, who lost a comeback Senate bid in 2016.

The elder Bayh first ran for the Senate in 1962 at the age 34, after serving four terms in the Indiana House of Representatives, where he became speaker at age 30. He made a short-lived bid for the Democratic presidential nomination in 1976.

After three terms in the Senate, he was swept out in the 1980 Ronald Reagan landslide (when Republicans picked up 12 seats), losing to congressman (and future vice president) Dan Quayle.
