Ignaz Friedman (also spelled Ignace or Ignacy; full name Solomon (Salomon) Isaac Freudman(n); February 13, 1882 – January 26, 1948) was a Polish pianist and composer. Critics (e.g. Harold C. Schonberg) and colleagues (e.g. Sergei Rachmaninoff) alike placed him among the supreme piano virtuosi of his day, alongside Leopold Godowsky, Moriz Rosenthal, Josef Hofmann and Josef Lhévinne.
