Jaap van Ginneken (b. 1943, Hilversum) studied social psychology, with mass psychology and mass communication as collateral subjects in Amsterdam, and did a Ph. D. with distinction on the history of political and mass psychology. He taught part-time at the (then) 'Baschwitz' Institute within the Political and Social Science Faculty; later at the Department of Communication Science. At the same time, he did a wide range of media projects, mostly on science communication. He is the author of 25 full-length/ single-author books: half aimed at larger audiences, half purely academic; half only in Dutch, half translated into English and other languages.
