text:  This is Fresh Air. Now we'd like to remember Dr. Ruth Westheimer, the 4'7", grandmotherly German Jewish psychologist who became an unlikely sex therapist on radio and TV. She died last week at the age of 96. Her matter-of-fact sex advice, along with her funny, lively personality, made her a national media celebrity. Here she is appearing on Late Night with Conan O'Brien in 1996, giving him some romantic advice.
