The story
Founded in 1891 by Patrick J. Cunningham, an Irish migrant with woodworking experience, the company manufactured acoustic upright, grand, and player pianos until 1943 when the factory ceased production.
In their first decade of manufacturing, Cunningham Piano Company gained recognition and became a popular piano-making company in Philadelphia's Germantown neighborhood.
During the 1920s, the heyday of the pneumatic player piano, Cunningham Piano Company was the largest manufacturer of player pianos in Philadelphia and shipped their wares to the entire East Coast of the United States.
Noted musicians used the instruments, including Vincent Persichetti, a native Philadelphian and noted composer and professor at the Juilliard School and George Gershwin who used a Cunningham Piano to write his opera "Porgy and Bess" in Folly Beach, South Carolina.
The Great Depression was a great blow to the business. Before the start of World War II, Cunningham Piano Company ceased production.
