Mieczysław Horszowski (June 23, 1892 – May 22, 1993) was a Polish-American pianist who had the longest known career in the history of the performing arts.
Born a Jew, Horszowski converted to Catholicism. One critic wrote: "Horszowski was both very Jewish and very Catholic, in both cases as only a Pole could have been."
In this video Horszowski performs Robert Schumann's Papillons, op. 2, in Paris in 1989, at the age of 97. He died in Philadelphia one month before his 101st birthday. He had given his final lesson the week prior to his death.
