Harold Ramis - a beloved actor, writer and director likely best known for his role in Ghostbusters - died early this morning at his home Chicago.
He was 69 years old.
Ramis' wife confirmed her husband's passing to The Chicago Tribune, saying the star passed away from a rare autoimmune disease at 12:53 a.m.
Born in The Windy City, Ramos grew up idolizing the Marx Brothers, Sid Caesar and Ernie Kovacs. He graduated in 1967 from Washington University.
His first job? The jokes editor for Playboy.
Ramis went on to join the improv group Second City, where he met two future famous friends and colleagues, John Belushi and Bill Murray.
