Actor, director and writer Harold Ramis died yesterday. He had been sick since 2010 with autoimmune inflammatory vasculitis, a rare disease that causes blood vessels to swell and forced him to re-learn how to walk. Ramis was probably best known for his role in “Ghostbusters”, which he also co-wrote, but he also directed “Caddyshack” and “Groundhog Day”, and co-wrote “Animal House.” He was born in Chicago but graduated from Washington University here in St Louis. Ramis said his inspiration for “Animal House” came from his experience with a Wash U frat house located on Forsyth. He has a star on the St Louis Walk of Fame on Delmar. Ramis was 69.
