Mamah Borthwick was an energetic, intelligent, and charismatic woman who earned a master's degree at a time when few women even attended college, translated writings by a key figure of the early feminist movement, and taught at one of Germany's best schools for boys. She is best known, however, as the mistress of the famous American architect Frank Lloyd Wright, and for her shocking murder at the renowned Wisconsin home he built for her, Taliesin. A Brave and Lovely Woman offers an important corrective to the narrative of Wright and Borthwick, a love story as American in character as it is Shakespearean in conclusion.

Little of Wright's life and work has been left untouched by his many admirers, critics, and biographers. And yet the woman who stood at the center of his emotional life, Mamah Borthwick, has fallen into near obscurity. Mark Borthwick-a distant relative-recenters Mamah Borthwick in her own life, presenting a detailed portrait of a fascinating woman, a complicated figure who was at once a dedicated mother and a faithless spouse, a feminist and a member of a conservative sorority, a vivacious extrovert and a social pariah. Careful research and engaging prose at last give Borthwick, an obscure but crucial character in one of America's most famous tragedies, center stage.
