Egon Spengler, PhD, is one of the main characters from the 1984 film Ghostbusters and its sequel Ghostbusters II, as well as the animated series The Real Ghostbusters. Portrayed by Harold Ramis in the films, Egon is the brains of the eponymous paranormal investigators, having created their equipment alongside his coworker, Ray Stantz. He is the most serious and rigid member of the team, but does not have much social ability, as shown by his stiff interactions with secretary Janine Melnitz, and relying on Peter Venkman as the group's spokesman.
