The Gelbs are renowned for their Eugene O'Neill biographies, and the new one, to be released Tuesday, pulls from previously sealed archival material. "By Women Possessed" is packed with riveting details and rich portraits of O'Neill and the people in his life, particularly third wife Carlotta. It's also just a great read. The relationship of Eugene and Carlotta is shown as loving at times, shot through with angst and anger at others; oh, the drama! O'Neill's treatment of previous wife Agnes and their children is portrayed in all its cold disdain. Arthur Gelb died at age 90 two years ago, as the Gelbs were working on the final revision to this tome. "By Women Possessed" is a fine last legacy, a tribute to his and his wife's work and their fascination with and exploration of O'Neill.
