Ruth Westheimer is an American sex therapist, media personality, and author best known as Dr. Ruth. The New York Times described her as a "Sorbonne-trained psychologist who became a kind of cultural icon in the 1980s.… She ushered in the new age of freer, franker talk about sex on radio and television—and was endlessly parodied for her limitless enthusiasm and for having an accent only a psychologist could have." Westheimer was born Karola Ruth Siegel in Wiesenfeld , Germany.

Westheimer earned a master's degree in sociology from The New School[9] and an Ed.D. from Teachers College, Columbia University. She completed post-doctoral work in human sexuality at New York-Presbyterian Hospital, training with pioneer sex therapist Helen Singer Kaplan.[3] She has written several books on human sexuality, including Dr. Ruth's Encyclopedia of Sex and Sex for Dummies. The full version of Dr. Ruth's Encyclopedia of Sex is currently available online. - wikipedia
