Shortly after he was 40, Wright’s life spun out of control. He became deeply depressed and, abandoning wife and children, deserted his practice, leaving behind debts and unfinished projects. He soon reappeared, however, with another woman. He built Taliesin, a studio/home in Wisconsin. This new mistress and their children were brutally murdered, and Taliesin burned to the ground. Wright soon took up with another woman, and then another, and another. His last wife, Olgivanna, picked up the role his mother had played; she ran the day-to-day operations and dealt with the household and studio.
