Harold Ramis, 69, passed away at his home in Chicago, IL., surrounded by family. The cause of death is attributed to complications from autoimmune inflammatory vasculitis, a rare disease which causes swelling of the blood vessels.


According to the Chicago Tribune, Ramis' serious health struggles began in May 2010 with an infection that led to complications related to the autoimmune disease, his wife said. Ramis had to relearn to walk but suffered a relapse of the vaculitis in late 2011, said Laurel Ward, vice president of development at Ramis' Ocean Pictures production company.

Ramis leaves behind a formidable body of work, with writing credits on such enduring comedies as "National Lampoon's Animal House" (which upon its 1978 release catapulted the film career of John Belushi, with whom Ramis acted at Second City), "Stripes" (1981) and "Ghostbusters" (in which Ramis also co-starred) plus such directing efforts as "Caddyshack" (1980), "National Lampoon's Vacation" (1983), "Groundhog Day" and "Analyze This."

Ramis is survived by his wife Erica, sons Julian and Daniel, daughter Violet, and two grandchildren.
