Cast-Iron Piano Frame
Patent #: 4292x
The dominance of the American piano industry rested on a key innovation patented by piano builder Alpheus Babcock in 1825. Babcock was the first to develop a one-piece cast iron frame to hold piano strings under tension.
Born in Dorchester, Massachusetts, Babcock was the son of a music teacher. He apprenticed as a piano maker and entered into a partnership with his brother making pianos in Boston by 1810. Through a variety of short-lived companies and partnerships in Boston, Babcock made a reputation for himself as an expert, known for pianos of excellent tone and finish.
