The manufacturing facilities at East Rochester was comprised of a series of separate and individual factories planned so that manufacturing of the various instruments was carried on in an entirely individual and distinct manner, and by separate organizations, each under direction of men who had been associated with each respective make for many years, thus preserving, unimpaired, the individual and distinctive qualities of each piano. Combined they made a great and powerful contribution to the art of music, for each of the great instruments they produced will continue providing magnificent music for generations to come. Name brands built in East Rochester include Chickering & Sons, J & C Fischer, Wm. Knabe, Mason & Hamlin, and George Steck.

H. B. Tremaine was a business genius who brought about the commercial exploitation of the piano player on a big scale. Tremaine's father had built a successful small business making and cranked table-top-sized mechanical organs, a very popular item in homes in the late 1800's. He founded the "Aeolian Organ and Music Company" around 1888; the firm achieved considerable success with larger instruments and organs. His son took over in 1899 and immediately set about to apply his own business acumen to the company's affairs. With the newly perfected "Pianola,' he launched an aggressive advertising campaign which was entirely new to the stodgy piano business. With four page color advertisements (almost unheard of in that day) published in the popular magazines, he literally stunned the piano industry with the message that here, indeed, was the answer to everyone's prayer for music in the home! Tremaine and Pianola built an enormous business empire over the next thirty years. It wasn't long after the turn of the century that it was deemed desirable to "miniaturize" the clumsy Pianola and other similar, instruments so that they could be built directly inside the pianos. Within a few short years, the push up"players disappeared from the scene. By this time everyone got into the act, and every piano maker so manufactured a player of some sort.
