Timothy Perper and Martha Cornog enjoyed nearly thirty-five years of marriage by collaborating on books about sexuality and about graphic novels. They also published fiction in Analog and Oziana. Tim (PhD, CUNY) was teaching biology at Rutgers New Brunswick when he obtained a grant from the Harry Frank Guggenheim Foundation to study pickups in singles bars. In his book Sex Signals: The Biology of Love (1985), he described a body language sequence typical of courtship: approach-talk-turn-touch-synchronization. He told L.A. Life in 1995, "It is behavior, vivacity that attracts people, not looks, beauty, not elegance of dress." Later, he became fascinated by Japanese manga and anime, and coedited with Martha the collections Mangatopia (2011) and Graphic Novels Beyond the Basics (2009). Tim passed away in 2014. Martha (MA, Brown University; MS, Drexel University) has a librarian background and published the award-winning Libraries, Erotica, and Pornography (1992) and, also award-winning, The Big Book of Masturbation (2003). She worked with Tim on many of his creative projects and currently writes about graphic novels for Library Journal.
