#10: Steinway (New York)
Steinway & Sons, also known as Steinway, is an American-German piano company, founded in 1853 in Manhattan, New York City, by German immigrant Heinrich Engelhard Steinweg (later known as Henry E. Steinway). The company's growth led to the opening of a factory in Queens, New York City, and a factory in Hamburg, Germany. The factory in Queens supplies the Americas and the factory in Hamburg supplies the rest of the world.
Steinway has been described as a prominent piano company known for making pianos of high quality and for inventions within the area of piano development. Steinway has been granted 126 patents in piano making; the first in 1857. The company's share of the high-end grand piano market consistently exceeds 80 percent. The company's dominant position in the high-end piano market 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.
