Here's a mystery. Somebody left part of an upright piano, the heavy part, next to a garbage can in Morningside Park over the weekend. Who thinks "How should we get rid of our old piano? I know, let's take it apart and bring it to a park!"
The piano was made by Behning and Sons. A cursory search doesn't turn up much information about the company. Henry Behning started the business in 1856 and it became Behning and Sons in 1880. After Henry's death the name changed to the Behning Piano Co. I can't find a date. In 1926 the company was sold to Kohler. That would make this piano about a hundred years old, plus or minus a couple of decades.
Zip codes were introduced in 1963, so Hans Deutsch tuned this piano at least forty-five years ago. Mr. Deutsch lived in a handsome four-story townhouse at 38 W. 74th Street, just off Central Park.
