Thank you so much for this wonderful description of the Schleicher history in the manufacture of "pianos, planes, and putt-putt's".
I did sell my instrument in Sept 1999, although it is only about ½ hour drive away from me. I will let the current owners know about the story of the piano.
It's interesting that you say the piano company was first started sometime after 1864 by Gustave, and only stopped in the 1920's. I also did not know about the factories in Mount Vernon, NY and Ossining, NY. My only knowledge of the company came from the Bob Pierce Piano Encyclopedia (8th Ed, 1982) which only mentions the years 1909 and 1910, and only Stamford, CT. Since Bob posted all the information he received from many sources in his book, he obviously was not made aware of the story of the brothers and how they split up the business. From the serial number, I determined my piano was built in Stamford in 1910. I believe Bob is still alive in Long Beach, CA, but is quite advanced in years now. I am not sure if someone is continuing to publish his piano encyclopedia, but if so, I am sure they would like to know this information. I will check this out and get back to you on this forum.
Thank you again for your very complete information.
