Harold Ramis has died aged 69.
The writer/director/actor, most famous for playing Dr Egon Spengler in 1984's Ghostbusters , passed away in the early hours of this morning.
He was suffering from a rare disease called autoimmune inflammatory vasculitis, which involves the swelling of the blood vessels.
As well as making his mark as loveable nerd Spengler, Ramis also directed time-loop comedy Groundhog Day , Analyse This and four episodes of the US version of The Office .
He started out in show business working as joke editor for Playboy magazine.
It was in 1974 that he joined The National Lampoon Radio Hour , honing his natural comedic talent by writing and performing sketches alongside the likes of John Belushi and Bill Murray.
That led to a collaboration with Ivan Reitman on National Lampoon's Animal House , which was the beginning of a professional relationship that saw Ramis also working with Reitman and Murray on Meatballs , Stripes and Ghostbusters .
No matter what the project, Ramis was much-loved for his unshakeable sense of humour.
Ramis died with his family around him in North Shore.
Our thoughts are with his family at this difficult time.
