Masters and Johnson. William Masters (1915-2001) and Virginia Johnson (born 1925) were two researchers who took a biological and feminist approach to their studies of the human sexual response, which they performed from 1957 until the early 1990s. Differing from Kinseyâs method of using personal interviews, they used the direct observation method.
