 When Jaffe left Paramount in 1936 to set up his own talent agency, Gersh moved with him to work as an office boy earning $15 a week.His first client as an agent was director Mark Robson, with whom he had been in a fraternity at UCLA some years before, and who was looking to move into directing from a job as an editor at RKO Pictures.Gersh subsequently signed other directors from the studio including Robert Wise, Richard Fleischer and Joseph Losey, thereby establishing a reputation as an effective spotter of directing talent.
