What was the name of the woman killed at Taliesin in 1914? Her name was Mamah Borthwick.

Martha Bouton “Mamah” Borthwick was an American translator who had a romantic relationship with Frank Lloyd Wright. Both had left their spouses, and Wright built Taliesin near Spring Green, Wisconsin, partly as a home for their shared life. Their relationship attracted intense public criticism and press attention.

On August 15, 1914, Borthwick was at Taliesin with her children, John and Martha Cheney, while Wright was away in Chicago overseeing work on Midway Gardens. A Taliesin servant, Julian Carlton, attacked residents and workers, set part of the building on fire, and killed seven people, including Borthwick and her two children.

Borthwick is sometimes described simply as Wright’s “mistress,” but she was also a highly educated translator. She and Wright helped introduce American readers to the writings of Swedish feminist Ellen Key. Her death profoundly affected Wright and became one of the defining tragedies in the history of Taliesin.
