Robin the Boy Wonder was actually Dick Grayson, the youngest of a family of circus aerialists, who witnessed his mother and father plunging to their deaths from a sabotaged trapeze. This murder was also observed by wealthy socialite Bruce Wayne. Wayne took the youngster under his wing and, as his alter ego Batman, trained him as his partner. Thus, one of the most famous superhero teams—Batman and Robin, the Dynamic Duo—was born. Robin accompanied Batman on a host of 1940s and ’50s escapades in Detective Comics, Batman, and World’s Finest Comics, protecting Gotham City from routine thugs and a growing contingent of colourful rogues, including the Joker, Catwoman, and the Penguin. Robin appeared alongside Batman on the Superman radio program, and two movieserials, Batman (1943) and Batman and Robin (1949), were produced. Beginning in 1947 and continuing for several years thereafter, Robin was even awarded his own series in Star Spangled Comics.
