In the late 1930's, chemist Rex Tyler developed the revolutionary vitamin "Miraclo" and decided to make himself the first test subject. The drug gave him increased strength, stamina, speed, agility and limited invulnerability, but only for an hour at a time. Rex decided to use these abilities to fight crime as Hourman, joining the Justice Society of America and the All-Star Squadron to help America through World War II and beyond.
