Frank and funny, the taboo-breaking psychologist said things on television and radio that would have been shocking coming from almost anyone else.Ruth Westheimer, the grandmotherly psychologist who as “Dr. Ruth” became America’s best-known sex counselor with her frank, funny radio and television programs, died on Friday at her home in New York City. She was 96. Her death was announced by a spokesman, Pierre Lehu.Dr. Westheimer was in her 50s when she first went on the air in 1980, answering listeners’ mailed-in questions about sex and relationships on the radio station WYNY in New York. The show, called “Sexually Speaking,” was only a 15-minute segment heard after midnight on Sundays. But it was such a hit that she quickly became a national media celebrity and a one-woman business conglomerate.At her most popular, in the 1980s, she had syndicated live call-in shows on radio and television, wrote a column for Playgirl magazine, lent her name to a board game and its computer version, and began rolling out guidebooks on sexuality that covered the field from educating the young to recharging the old. College students loved her; campus speaking appearances alone brought in a substantial income. She appeared in ads for cars, soft drinks, shampoo, typewriters and condoms.She even landed a role in the 1985 French film “One Woman or Two,” starring Gérard Depardieu and Sigourney Weaver and released in the United States in 1987.

Talk shows abounded in the 1980s, but until she came along none had dealt so exclusively and clinically with sex. Nor could anyone have anticipated that the messenger of Eros would be a 4-foot-7 middle-aged teacher with a delivery that The Wall Street Journal described as “something like a cross between Henry Kissinger and a canary.” We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
