In this brilliant, groundbreaking biography, twenty years in the making, James H. Jones presents a moving and even shocking portrait of the man who pierced the veil of reticence surrounding human sexuality. Jones shows that the public image Alfred Kinsey cultivated of disinterested biologist was in fact a carefully crafted public persona. By any measure he was an extraordinary man--and a man with secrets. Drawing upon never before disclosed facts about Kinsey's childhood, Jones traces the roots of Kinsey's scholarly interest in human sexuality to his tortured upbringing. Between the sexual tensions of the culture and Kinsey's devoutly religious family, Jones depicts Kinsey emerging from childhood with psychological trauma but determined to rescue humanity from the emotional and sexual repression he had suffered. New facts about his marriage, family life, and relationships with students and colleagues enrich this portrait of the complicated, troubled man who transformed the state of public discourse on human sexuality.
