Haskell Wexler initiated his feature filmmaking career as a cinematographer in the late 1950s, having previously shot educational and industrial films. The Chicago native had traveled to California to attend Berkeley, but dropped out after one year. He served as a merchant seaman during WWII and then returned to Illinois. Wexler and his father purchased and refurbished an armory in Des Plaines, turning it into a film studio. The venture was unsuccessful and Wexler set out to learn about film production, beginning as a cameraman and eventually working up to cinematographer."Stakeout on Dope
