A servant of American architect Frank Lloyd Wright murders seven people and sets fire to the living quarters of Wright's Wisconsin home, Taliesin.

Frank Lloyd Wright (June 8, 1867 April 9, 1959) 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 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".Wright was the pioneer of what came to be called the Prairie School movement of architecture and also developed the concept of the Usonian home in Broadacre City, his vision for urban planning in the United States. He also designed original and innovative offices, churches, schools, skyscrapers, hotels, museums, and other commercial projects. Wright-designed interior elements (including leaded glass windows, floors, furniture and even tableware) were integrated into these structures. He wrote several books and numerous articles and was a popular lecturer in the United States and in Europe. Wright was recognized in 1991 by the American Institute of Architects as "the greatest American architect of all time". In 2019, a selection of his work became a listed World Heritage Site as The 20th-Century Architecture of Frank Lloyd Wright.

Raised in rural Wisconsin, Wright studied civil engineering at the University of Wisconsin and then apprenticed in Chicago, briefly with Joseph Lyman Silsbee, and then with Louis Sullivan at Adler & Sullivan. Wright opened his own successful Chicago practice in 1893 and established a studio in his Oak Park, Illinois home in 1898. His fame increased and his personal life sometimes made headlines: leaving his first wife Catherine Tobin for Mamah Cheney in 1909; the murder of Mamah and her children and others at his Taliesin estate by a staff member in 1914; his tempestuous marriage with second wife Miriam Noel (m. 19231927); and his courtship and marriage with Olgivanna Lazovi (m. 19281959).

An architect is a person who plans, designs and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latin architectus, which derives from the Greek (arkhi-, chief + tekton, builder), i.e., chief builder.The professional requirements for architects vary from place to place. An architect's decisions affect public safety, and thus the architect must undergo specialized training consisting of advanced education and a practicum (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction, though the formal study of architecture in academic institutions has played a pivotal role in the development of the profession as a whole.
