A pianist and composer of tremendous popularity, Jan Paderewski made his U.S. debut in 1891 and became the most loved pianist since Franz Liszt. Paderewski was paid large sums for his concerts, and during 1914-1918 he donated his concert receipts to Polish war victims. He also established scholarship endowments for young musicians. Following World War I, Paderewski served first as the Polish representative to Washington and then as his nation's prime minister. During 1940-1941, he led the exiled Polish government during the German occupation.
