In 1882, Paul von Jankó invented a keyboard where any pattern can be fingered in the same way in every key, There are 88 key levers just like a normal piano, but each key lever has three key tops. The keys are arranged in two rows of whole tone scales offset by a semitone. They were produced by over 50 manufacturers. There was a Paul von Jankó Conservatory in New York dedicated to teaching it. Franz Liszt said of it "This invention will have replaced the present piano keyboard in fifty years' time!". Arthur Rubinstein said "If I were to begin my career anew it would be on this keyboard". Many experts and music educators of the time thought that the dominance of "the new keyboard" was an inevitability. An 1889 book stated "the victory over the old keyboard is now merely a question of time". But by 1920, they had all but vanished. The traditional keyboard just had too much inertia to overcome.
