Harry_"A"_Chesler

Harry Chesler (January 12, 1897, or January 12, 1898 (sources differ) – December 29, 1981), often credited as Harry "A" Chesler, with the "A" an affectation rather than a true initial, was the entrepreneur behind the first comic book packager of the late-1930s to 1940s Golden Age of comic books, supplying comics features and complete comic books to publishers testing the waters of the emerging medium.
Chesler's studio, which began in either 1935 or 1936, provided early work to artists and writers including Jack Cole, Jack Binder, Otto Binder, Charles Biro, Mort Meskin, and many others.
