He was born in
Kuppenheim,
Germany, the son of a cattle dealer. In 1920, the brothers were approached by the British publishers,
Chappell & Co., to handle their interests in the US. By 1926, they had bought Chappell outright, and shortly before the
Great Depression they made a highly profitable sale of their interest in T. B. Harms. The companies remained independent of the
Hollywood system which bought up many of the other publishing houses, with the result that the brothers retained a strong financial position. In 1935, they reconstituted their holdings as Chappell, Inc., with Louis Dreyfus moving to London and Max remaining in control of their New York operations, based in the
Rockefeller Center. Max Dreyfus was "a soft spoken, slightly built man who was reserved almost to a fault." He was seen as a "man of integrity" and a "gifted talent spotter". He helped found
ASCAP (the American Society of Composers, Authors and Publishers) in 1914, and served as a board member for fifty years until shortly before his death. He pioneered a new style of
orchestration for
theatre performances, employing
Russell Bennett as the company's chief orchestrator from 1919. He established a company policy under which composers,
lyricists and
librettists were all in partnership with the publishing company. He insisted on exclusive contracts for many of his writers and orchestrators working on
Broadway shows, with the result that "through the thirties and forties, Dreyfus had a virtual stranglehold on the Broadway musical, with almost all of the most successful songwriters (except
Berlin) under contract. And the best and most knowledgeable theatrical orchestrators as well." He remained in control of Chappell & Co. after
World War II, with new writers including
Alan Jay Lerner and
Frederick Loewe, whose
My Fair Lady he published. Although other independent publishers took a larger share of the market after the war, Chappell also found success with
South Pacific,
The Sound of Music,
Gypsy, and
Funny Girl, among others. Dreyfus was played by
Charles Coburn, who was considerably bulkier and more gregarious than him, in the 1945 Gershwin biographical film
Rhapsody in Blue. Dreyfus did not like the film, saying to a friend, “Did you ever see me wear a top hat ?” ==Personal life==
