Robotman was created by Jerry Siegel and Leo Nowak. He first appeared in Star Spangled Comics #7.
Robert Crane is a scientist whose brain was placed inside a robotic body after he had been fatally shot. Since Crane had to be legally dead for his assailants to be charged with murder, he created a civilian identity as Paul Dennis, accomplished with lifelike face mask and gloves. As Robotman, he was a member of the World War II-era team, the All-Star Squadron.
