An immense labour was involved before a composer’s music could reach its public. The journey from first thoughts to first night relied on the collaboration of many individuals operating in interlocking disciplines, and none were more important to that endeavour than music publishers and agents with the firm. In Britten’s case, the most important firms are Boosey & Hawkes and Faber & Faber. This chapter portrays those who worked closely with Britten as his publishers, who supported him and championed his music, including Ralph Hawkes, Erwin Stein, Hans W. Heinsheimer, Ernst Roth, Leslie Boosey, Anthony Gishford, and Donald Mitchell. Many of these individuals formed extremely close relationships with Britten, but equally, their associations were sometimes complex or fraught.
