Writer-Producer Robert Youngson’s seminal compilation documentaries of silent comedy in the 1960s inspired a Renaissance in the legacies of Charley Chase, Snub Pollard, and, above all, Laurel and Hardy as well as other comedians from movies of the teens and twenties. Youngson died young, but his widow, Jeanne, tells author Manago about her late husband’s obsession with movies, laughter, and food.
