From mid-1943 until late-1950, Eric Crozier was an essential asset to Britten’s industry. His work alongside director and radio producer Tyrone Guthrie not only introduced Crozier to the Old Vic in London, but to the BBC as well, where Guthrie also worked. Joan Cross invited Crozier and Guthrie to each direct two different productions at Sadler’s Wells in 1943. Crozier directed and produced Britten’s first two operas, Peter Grimes in 1945 at Sadler’s Wells, and The Rape of Lucretia in 1946 for the short-lived Glyndebourne English Opera Company. Crozier wrote the librettos for Albert Herring and the children’s entertainment Let’s Make an Opera (with its central opera, The Little Sweep), in addition to writing the text for the cantata Saint Nicolas, and with E. M. Forster, he was co-librettist for Billy Budd. Britten, Crozier, and designer John Piper founded the English Opera Group. The endeavour was based on ‘the Britten–Crozier doctrine’ that sought the group’s own autonomy and ultimately a home to produce such works. That home was largely realised in the founding of the Aldeburgh Festival of Music and the Arts in 1948, for which Crozier was a founder and co-artistic director.
