Q.E.D. is a 1982 short-lived adventure series set in Edwardian England, starring Sam Waterston as Professor Quentin Everett Deverill. The Professor was a scientific detective in the mold of Sherlock Holmes, and the series had a smattering of what would later be called steampunk.
In the show, the lead character was known primarily by his initials, Q.E.D; the reference here is that Q.E.D. usually stands for quod erat demonstrandum, a statement signalling the end of a proof.
