Ignacy Tiegerman (24 February 1893 – 31 May 1968), usually seen as Ignace, but also Ignaz, was a Polish pianist and teacher. He was an exceptional interpreter of the Romantic school (Field, Chopin, Brahms, et al.). He studied with Theodor Leschetizky but his lessons with Leschetizky's assistant Ignaz Friedman were more significant. Tiegerman considered Friedman his mentor, and Friedman deemed him "the greatest talent I ever worked with."
