Marjorie B. Garber (born 11 June 1944) is a professor at Harvard University and the author of a wide variety of books, most notably ones about William Shakespeare and about sexuality. She wrote Vested Interests: Cross-Dressing and Cultural Anxiety, a ground breaking theoretical work on transvestitism's contribution to culture. Other works include Vice Versa: Bisexuality and the Eroticism of Everyday Life, Shakespeare After All, and Dog Love (which is not primarily about bestiality, except for one chapter titled "Sex and the Single Dog").
