Daredevil is a fictional superhero created by Jack Binder. As a child, Bart Hill was witness to his parents' brutal murder. The murderer also branded Bart with a hot iron, leaving a boomerang-shaped scar on the left side of his chest. This traumatic experience left the boy mute. He trained his entire life in the art of the boomerang, eventually becoming a master boomerang marksman. He then donned a costume and took to the streets as the vigilante crime-fighter known as Daredevil. Lev Gleason launched Daredevil's own comic with Daredevil Battles Hitler #1 (July 1941), in which Daredevil and other Silver Streak heroes fought the German chancellor. It was written and partially drawn by Charles Biro, who in his 16-year run would make the character one of the most acclaimed of the Golden Age. Collects Silver Streak #6-17 (September 1940-December 1941) and Daredevil Battles Hitler #1 (July 1941).
