Edgar "Ed" Heyl (July 1, 1911 - May 23, 1993), born in Philadelphia and a chemist employed by the State of Maryland, was a magic performer, scholar, collector and later magic dealer in Baltimore. His father (Earle) was also an amateur magician of note from Baltimore. After retiring as a chemist, he worked for the Genealogical Publishing Co., where he was responsible for the compilation of catalogs. They moved to Baltimore in 1933. In the 1940s, his father did radio shows on magic history and anecdotes. Heyl was president of the Demons Club (SAM Assembly No. 6) of Baltimore in the 1940s. He had a column in MUM called "Cues For Collectors" in 1953, which was later compiled and published as a pamphlet. He was an avid collector, especially of magician tokens and playing cards, and was the editor of The Magic Collector's Association's newsletters, which he was one of the first members. He also wrote for the Journal of the Token and Medal Society.
