Sir Jonathan Wolfe Miller CBE was a British theatre and opera director, author, television presenter, humorist and sculptor. Trained as a physician in the late 1950s, he first came to prominence in the 1960s with his role in the comedy review Beyond the Fringe with fellow writers and performers Peter Cook, Dudley Moore and Alan Bennett. Despite having seen few operas and not knowing how to read music, he began stage-directing them in the 1970s and became one of the world's leading opera directors with several classic productions to his credit. His best-known production is probably his 1982 "Mafia"-styled Rigoletto set in 1950s Little Italy, Manhattan. He was also a well-known television personality and familiar public intellectual in the UK and US.
This very fine book is a collection of essays centered around Mozart's opera, but more broadly around the myth of Don Juan. By and large the essays are not so much about the music as about the character of the libertine. The range of contributors is quite wide, so the perspectives gained are not narrow at all. I recommend it highly.
