He was the son of Heinrich Engelhard Steinway (originally Steinweg) who emigrated from Germany to New York City in 1850. By 1853, Heinrich and his sons had opened their own Steinway & Sons shop dedicated to selling their namesake pianos. William was the entrepreneurial genius of his family; his promotional and marketing techniques, cultivation of eminent musicians, and extensive participation in the musical life of New York City made Steinway & Sons extraordinarily successful.
