Mr. Raymond got his start in the 1920s, working the stages of the old Catskill resorts. Though he went on to appear in countless movies, television shows and commercials, he made it to Broadway only once, in 1968's Golden Rainbow. The Walter Marks musical starred Steve Lawrence and Eydie Gorme, and went through terrible backstage trauma, jettisoning a couple bookwriters and a choreographer before finally opening to mixed reviews. Based on Lawrence's appeal, the show ran for nearly a year. In films, his roles were typically small and often uncredited. Among his most famous credits are "The Hustler," "Making Mr. Right" and "Let It Ride." Mr. Raymond may have achieved his most lasting notoriety as the voice of various popular cartoon characters of the 1950's. He voice the slow-witted, giant cartoon duck Baby Huey, the mouser Catnip—both creations of Harvey Comics—and the mischievous twin magpies Heckle and Jeckle. Mr. Raymond was also an adept mimic who could ape the voices of stars like Edward G. Robinson and Jerry Lewis.

In 2002, he was the subject of a short documentary called "Sid at 90."

He is survived by his wife of 69 years, the former Dorothy Naftel, and daughters, Cynthia Raymond and Margo Cohen, both of Manhattan; his sisters, Ruth Freedman, of Manhattan, and Dorothy Amcher, of Orlando; and one granddaughter.
