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.
Ramos wrote Animal House and directed Caddyshack and portrayed the dry, sarcastic, intelligent Dr. Egon Spengler in Ghostbusters.
He wrote the Ghostbusters and Caddyshack sequels, as well as Groundhog Day. Ramos also played the dad of the Seth Rogen's character in 2007's Knocked Up.
Ramos is survived by his wife, Erica, along with their two sons, Julian and Daniel, and a daughter from his first marriage to Anne Plotkin, Violet Ramis.
We send our condolences to the actor's loved ones and to the family, friends and colleagues of the other stars we've already bid farewell to this year ....
