McEwen (European history, Creighton U., Nebraska) explores how knowledge about sex was made and shared in Vienna from the explosion of sexual science in the late Imperial period to the incomplete cultural revolution wrought by the Social Democratic Workers' Party, which ended in 1934. The purpose of sexual knowledge shifted, she finds, from medical science to heal individuals at the turn of the century, to social science to replenish the population after World War I. She attributes the discourse of sexual danger to the fear of venereal infection from returning soldiers. Annotation ©2012 Book News, Inc., Portland, OR (booknews.com)
