Los Angeles Oratorio Society

The Los Angeles Oratorio Society was a choir in Los Angeles, California that primarily performed oratorios. Founded in 1893 by conductor F. A. Bacon, the chorus was active in Los Angeles into the 1950s. The profile of the chorus was significantly raised during the tenure of conductor John Smallman who became conductor in 1912. He was succeeded by conductor Richard Lert. Under Lert's tenure the ensemble served as the official chorus of the Los Angeles Philharmonic in the late 1930s and 1940s.
