Frank Lloyd Wright was born in 1867 in Wisconsin to parents who wanted him to become an architect. After his father left when he was a teenager, Wright took drafting classes and began working for architects in Chicago, including Louis Sullivan. Two of Wright's most famous works are Fallingwater, a private home built over a Pennsylvania stream in 1936, and the Guggenheim Museum in New York, which features a distinctive spiral design and was completed in 1959. Wright is considered one of the greatest architects of all time.
