- New 5-story Chickering & Sons factory opens in Boston, reputed to be the second-largest building in America (after the Capitol Building in Washington, D.C.). The factory houses 5,000 workers and can build 2,000 pianos per year.
- Steinway & Sons builds 11 square pianos, according to the “Number Book”.
- The Steinways begin to cultivate valuable business relationships, often relying on their German origin. In the mostly German-dominated New York musical scene, notable musicians of German heritage – conductors Theodore Thomas and Carl Bergmann, pianist Hermann Wollenhaupt, as well as American pianist William Mason (who studied in Germany with Franz Liszt and Ignaz Moscheles), become the first endorsers of Steinway & Sons pianos.
