The History of Janssen Piano Company
Founded by B.H. Janssen in 1901, the Janssen Piano Company factory was located in New York City. As one of the few family-owned piano companies throughout the 1900s, Janssen became associated with Horace Water in New York around 1930. Janssen pianos were known for their various upright and grand piano varieties that were quality built while remaining affordable. 
Janssen was purchased in 1970, by Charles and Barbara Walter to become part of the Charles R. Walter piano company. At that time, the factory was moved to Indiana where Janssen pianos continued to be produced until the 1980s.
About Janssen Pianos
Many of the Janssen piano features were improved over time since production remained in the hands of a small family group and private ownership. For instance, their four-section cast iron plate allowed for longer durability and better tone quality. They marketed their pianos as having a Direct-Blow action, Sitka spruce soundboards and moth-proof hammers. 
The detailed features like the built-in fluorescent lights in the console made it the perfect in-home practice or playing piano. Janssen also introduced several interesting piano variations like their Janssen Spinet which is the smallest spinet piano in the world with a full keyboard.
Janssen produced pianos under the following names throughout the 1900s:
Charles R. Walter
