David Platz (January 13, 1929 – May 20, 1994) was a German-born British music publisher and music business executive who established and led Essex Music, one of the major independent music publishing companies of the 1960s and 1970s. He also set up the Fly and Cube record labels.
He was born in Hanover, Germany, and was sent to London with his sister at the age of 10 to escape the Nazi persecution of the Jews. He lived in Neasden with guardians, and after leaving school began work as a messenger in Southern Music, a music publishing business in Denmark Street, Soho. He rose to become the manager of a section specialising in Latin American recordings, before leaving in 1955 to set up Essex Music with American music publisher Howie Richmond.
The company quickly became successful, and Platz attracted a wide variety of musicians to use the agency, including the Rolling Stones, the Moody Blues, the Move, Procol Harum, the Who, Johnny Dankworth, Dudley Moore, Lonnie Donegan, David Bowie, and Marc Bolan. For each writer, Platz established a separate division of the company, with the artist maintaining direct involvement in its control.
