Julius Chaloff (September 2, 1892 – October 28, 1979) was an American pianist and composer. Born of Russian parentage in Boston, Massachusetts, he was the son of Cantor Israel Chaloff, of Congregation Ohabei Shalom, then located in Boston. In 1919, he married a fellow musician, Margaret Stedman. Chaloff was the father of jazz baritone saxophonist Serge Chaloff. Serge gained his earliest prominence as a member of Woody Herman's second herd also known as the Four Brothers. Chaloff was also father of Richard Stedman Chaloff Sr. who founded Stedman Ltd. of Brookline, one of the first custom audio / video installation businesses in the country. Chaloff was married to piano instructor Madame Margaret Chaloff, née Stedman, whose students included Keith Jarrett, Kenny Werner, Chick Corea, Herbie Hancock, Mulgrew Miller, Toshiko Akiyoshi, and Steve Kuhn.
As a child, Chaloff showed exceptional musical talent, and at the age of eleven entered the New England Conservatory of Music, studying piano with Alfred Devoto. He studied at this institution for six years and was the youngest student to receive a diploma, graduating with high honors at the age of 17. During the senior year he won the first Mason and Hamlin prize piano contest, the judges being George W. Chadwick, Charles Martin Loeffler, and Dr. Max Fiedler.
