Ted Knight was a wealthy, genius scientist that helped develop the Atomic Bomb. He invented the Gravity Rod and used it to become the hero known as Starman. Starman was Opal City's beloved protector and a member of the Justice Society of America. He passed the Starman mantle and Gravity Rod along to one of his sons but has since died of old age. Recently, Opal City opened the Starman Museum in his honor though.
