Ramis was a writer, director and actor whose energetic but sly silliness helped catapult comedies like Groundhog Day, GhostbustersAnimal House and Caddyshack to commercial and critical success. He also directed such comedy classic's as National Lampoon's Vacation, Analyze This, Year One, Multiplicity, Analyze That, and The Ice Harvest to name a few.

He was truly a master at knowing what made people laugh. As he once said himself, “We represent the underdog as comedy usually speaks for the lower classes,” “We attack the winners.”

Harold Ramis died of complications of autoimmune inflammatory vasculitis, a disease that involves swelling of blood vessels. He was 69 years old.
