Kalman Bloch (May 30, 1913 in Harlem – March 12, 2009 in Los Angeles) was principal clarinetist of the Los Angeles Philharmonic for more than 40 years. Bloch studied with Simeon Bellison, a notable clarinetist for the New York Philharmonic. As recounted by Dorothy Lamb Crawford in her 2009 book "A Windfall of Musicians:Hitler's Émigrés and Exiles in Southern California," Bloch was hired at the age of 21 by then music director and recent Jewish emigre Otto Klemperer just before the onset of World War II.
