Steinway & Sons, also known as Steinway, () is an American-German piano company. It was founded in 1853 in Manhattan, New York City, the United States, by German piano builder Heinrich Engelhard Steinweg (later known as Henry E. Steinway). The employees at Steinway were mostly German immigrants. The company's growth led to the opening of a factory in Queens, New York City, the United States, and a factory in Hamburg, Germany. The factory in Queens supplies the Americas and the factory in Hamburg supplies the rest of the world.
