The story
The village of East Rochester, New York, originally named Despatch after the transportation company that spawned several dozen car shops in the area, was also home to a musical manufacturing giant for the better part of the 20th century. Nestled in between the New York Central Railroad tracks and Commercial Street, the 250,000 square-foot edifice designed by Henry Ives was the first industrial building in the United States to be constructed from reinforced concrete.
Renowned for its fine craftsmanship, the American Piano Company was the largest distributor and manufacturer of pianos in the world by the mid-1920s. The instrument's popularity reached its peak that decade thanks to a growth in prosperity and an increased interest in music stimulated by phonographs and radio. Piano producers across the country would not fare as well the following decade. Over 347,000 pianos were purchased in the United States in 1923,.
