Virginia Johnson was a sex therapist famous for her work assisting William Masters in his research about human sexuality and sexual response. The pair worked together for more than three decades, transformed society’s attitudes towards sexuality, and were married from 1971 to 1993. Their professional relationship continued after their divorce.
Together, Masters and Johnson identified the four stages of sexual response: excitement, plateau, orgasm, and resolution. They brought words like "masturbation," "clitoris," and "orgasm" to the mainstream, and helped individuals overcome sexual dysfunction.
Virginia Johnson died in 2013 in Missouri.
