When trying to come up with the perfect name for his character in Ghostbusters—who was the brains of the Ghostbusters—co-writer Harold Ramis combined both personal and academic inspirations. “Egon” was the first name of Egon Donsbeck, a Hungarian exchange student at Stephen K. Hayt Elementary School who was Ramis' classmate when he grew up in Chicago. “Spengler” came from German historian and philosopher Oswald Spengler.
