Steinway & Sons

Steinway & Sons, also known as Steinway (/ˈstaɪnweɪ/ ), is a German-American piano company, founded in 1853 in New York City by German piano builder Heinrich Engelhard Steinweg (later known as Henry E. Steinway). The company's growth led to a move to a larger factory in New York, and later opening an additional factory in Hamburg, Germany. The New York factory, in the borough of Queens, supplies the Americas, and the factory in Hamburg supplies the rest of the world.

Steinway is a prominent piano company, known for its high quality and for inventions within the area of piano development. Steinway has been granted 139 patents in piano making, with the first in 1857. The company's share of the high-end grand piano market consistently exceeds 80 percent. The dominant position has been criticized, with some musicians and writers arguing that it has blocked innovation and led to a homogenization of the sound favored by pianists.
