A radio actress for two decades before television made her voice familiar in a different way, Gerson became the voice of Cruella de Vil in One Hundred and One Dalmatians (1961) — a performance so definitive that Disney named her a Disney Legend in 1996, decades after the film's release. Her career otherwise spanned live radio drama, film, and early television, but it is that one villain's voice that endures.
