It was built between 1899 and 1904 and designed by Paul E. M. Duboy.","why_significant":"The nomination argues the Ansonia is a distinctive example of turn-of-the-century urban Beaux-Arts architecture with richly decorated surfaces. It was also the largest apartment-hotel in the world, with advanced fireproof and virtually soundproof construction. It is world-renowned as a residence for musicians and theatrical figures, which also gives it significance in music education.","narrative":"Rising seventeen stories over the Broadway blockfront between 73rd and 74th Streets, the Ansonia was built from 1899 to 1904 as an apartment-hotel designed by French architect Paul E. M. Duboy in the Beaux-Arts style. Developer William Earl Dodge Stokes directed its design and construction, using all-masonry construction and thick partitions to make it fireproof and nearly soundproof. White-glazed terra cotta, limestone, ornamental ironwork and domed corner towers give the massive building a surprisingly light character. It opened with two swimming pools and a roof garden, and was the largest apartment-hotel in the world. Its soundproofing helped make it a home for musicians, including Enrico Caruso, Igor Stravinsky, Arturo Toscanini and Yehudi Menuhin, and its apartments hosted countless music lessons. Later changes include shopfronts at ground level, missing balconies and cupolas, and the division of about 300 original suites into roughly 540 apartments. The ornate iron and marble main staircase survives as the key original interior feature.","period_of_significance":"1899-1904","architect_builder":"Paul E.M.
