The Tonophone brought about a commercial agreement between de Kleist and Wurlitzer, cemented in 1901 after Allan Herschell left the Armitage Herschell Company due to financial complications. This allowed de Kleist to buy Armitage Herschell out, and seek new investment from his association with Wurlitzer. After de Kleist was voted in as mayor of North Tonawanda in 1906, Wurlitzer bought him out of the business in 1908. After his term as mayor ended, suffering from ill health, de Kleist retired to
Berlin in 1911, dying in
Biarritz, in 1913 from a
heart attack. The company was renamed the
Rudolph Wurlitzer Company of North Tonawanda. This allowed the company to invest in new technology, resulting in the adoption of electric motors, and the music source was changed from pinned barrels to perforated paper rolls similar to a player piano roll. Some larger organs such as the style 157 and style 165 have duplex roll frames, on which one roll plays while the other rewinds, allowing for continuous music. Each paper roll contained about 10 songs, but during the Great Depression, this was changed to 6 longer songs, in order to save money on arranging. The only substantial changes between these organs and the originals they were based upon is that the Wurlitzer models is that they operated on Wurlitzer's unique roll scale. These included the 46-note style 125 roll (used by styles 104, 105, 125, and smaller organs that saw less production), the wider 46-mote 150 roll (used by styles 146, 153, and other less common mid-size styles), or the still wider 75-note 165 roll (used by styles 157, 165, and larger special organ models). Due to Wurlitzer's success and domination of the market, many smaller American manufacturers adopted scales similar to Wurlitzer's, but to little effect. During the Great Depression leading up to the end of production of organs, various cost-cutting measures were made, such as the substitution of brass horn and trumpet pipes for ones made of wood (though arguably, the brass pipes produced a shrill and unpleasant sound, thus causing the change to the mellower wooden sound). The production of Wurlitzer organs ceased in 1942, the last organ to leave the factory being a style 165 organ in a 157 case (done because Wurlitzer had an extra 157 case still in the factory and the owner didn't mind the change). After the end of
World War II, during which the company helped develop and then produce the variable timing
proximity fuze for the
US Navy, production changed to producing a variety of items, including radios, jukeboxes and electronic organs. The plant closed in 1973 and was purchased, in the early 1980s, by a group of investors with the goal of turning the old plant into an industrial park. ==Present==
