Martha Bouton "Mamah" Borthwick was an American translator who had a romantic relationship with architect Frank Lloyd Wright, which ended when she was murdered. She and Wright were instrumental in bringing the ideas and writings of Swedish feminist Ellen Key to American audiences. Wright built his famous settlement called Taliesin in Wisconsin for her, in part, to shield her from aggressive reporters and the negative public sentiment surrounding their non-married status. Both had left their spouses and children in 1909 in order to live together and were the subject of relentless public censure. In 1914, a disturbed member of the staff at Taliesin suddenly went on a murder-suicide spree at the estate killing Borthwick, two of her children and others. Wright was away at the time.

Frank Lloyd Wright Sr. was an American architect, designer, writer, and educator. He designed more than 1,000 structures over a creative period of 70 years. Wright played a key role in the architectural movements of the twentieth century, influencing architects worldwide through his works and mentoring hundreds of apprentices in his Taliesin Fellowship. Wright believed in designing in harmony with humanity and the environment, a philosophy he called organic architecture. This philosophy was exemplified in Fallingwater (1935), which has been called "the best all-time work of American architecture".
