Starman (Ted Knight) – This Day In Comics
Ted Knight is the original super-hero to use the name Starman. Beginning adulthood as a wealthy heir in Opal City, he dedicated himself to science and developed the Gravity Rod. This allowed him to manipulate energy, and his cousin Phantom Lady encouraged him to become a super-hero. His girlfriend during this time was Doris Lee. He was a member of the All-Star Squadron and the Justice Society. Following his retirement, he married Adele Drew and passed the legacy onto his children David Knight and Jack Knight. Eventually he died in battle with his old enemy the Mist. Ted Knight was created by Gardner Fox and Jack Burnley, first appearing in Adventure Comics #61. (1941)
