In 1942, Ignacy Jan Paderewski (1860-1941), the great Polish pianist and composer (and in 1919 prime minister of Poland for one year), was posthumously honoured with a deluxe edition for which many of his friends and pupils, such as Béla Bartók, Darius Milhaud, Bohuslav Martinů or Jaromír Weinberger, specially composed piano pieces.
