The book for the first time explores in-depth the life and work of Herta Herzog (1910–2010), an Austrian-American social psychologist. Herzog spent most of her working life in the United States, where she moved to in the 1930s, following her first husband Paul Lazarsfeld into migration and working with him at the famous Office of Radio Research in Princeton and Columbia. The chapters by scholars from the U.S., Israel, Germany and Austria show the amazing scope of Herzog's work as both, one of the founders of empirical communication research and the "grand dame" of market and motivation research. Herzog crossed many borders, moving from Europe to the U.S. and back again, stepping over disciplinary lines as well as restrictions by gender.
