Homer Mensch (November 14, 1914 in Sussex, New Jersey – December 9, 2005 in Manhattan, New York) was a prominent classical bassist who was a former member of the Pittsburgh Symphony, the New York Philharmonic, the New York Pops, and the NBC Symphony. Mensch held faculty positions at Yale University, at the Manhattan School of Music (in both the college and pre-college divisions), the Juilliard School (also in both divisions), the Mannes College of Music, Rutgers University, Dalcroze School, Queens College, and Catholic University. He taught upwards of 45 students a week from beginners, to conservatory students, to professionals both in the classical and jazz fields.
Mensch studied bass with former New York Philharmonic principal bassist Anselme Fortier at the Manhattan School of Music. As a teenager, he played with the Dick Messner Big Band at the Hotel McAlpin in order to pay for his bass lessons. He was an excellent tennis player in his youth, and originally wanted to pursue a career in tennis. However, he was also a promising bassist and eventually chose music over tennis. "This was at the start of the Great Depression", he told the Juilliard Journal, "so pursuing a career in music was pretty risky. I was lucky that my parents didn't try to make me go into a field that was a safer bet."
Mensch joined the Pittsburgh Symphony in 1932 after winning the audition on the stage of Carnegie Hall in front of Otto Klemperer. He was assistant principal bass under Klemperer and Fritz Reiner until 1938. He then joined the New York Philharmonic under John Barbirolli. In 1943, Mensch left the Philharmonic to serve in the U.S. Army in Texas, during which time he played bass in the U.S. Army Band.
