Alpheus Babcock

Alpheus Babcock (September 11, 1785 – April 3, 1842) was a piano and musical instrument maker in Boston, Massachusetts, and Philadelphia, Pennsylvania, during the early 19th century. Babcock is best known for patenting a complete iron frame in a single casting, which better resisted the tension of the strings in square pianos. All modern pianos use this method of a single cast iron frame. He also patented a system of stringing in squares and improvements in piano actions.
