Biographer Larry Tye can't help but be entertained by his subject's professional antics. Edward L. Bernays (1892-1995), a pioneering practitioner of public relations, zestfully ballyhooed his clients, utilizing a shrewd blend of publicity stunts, careful cultivation of the press, and solicited endorsements from "experts." Yet journalist Tye is also aware of the moral ambiguities inherent in the career of a man who vigorously promoted cigarette smoking and whose work for the United Fruit Company played at least some role in the 1954 military overthrow of Guatemala's democratically elected government. This judicious book balances appreciation for Bernays' inventiveness with a sober understanding of its consequences, including the extent to which PR permeates contemporary American life. --Wendy Smith
