John Bröcheler was a Dutch operatic baritone who began as a concert singer, specializing in contemporary music such as the world premiere of Mauricio Kagel's Mare Nostrum. He was a member of the Dutch National Opera from the 1970s to 2002. His appearance there in Donizetti's Maria Stuarda alongside Joan Sutherland was followed by an international operatic career, performing for example as Mandryka in Arabella by Richard Strauss at the Glyndebourne Festival and in more world premieres such as Menotti's La Loca at the New York City Opera and the complete version of Henze's König Hirsch at the Staatsoper Stuttgart. He portrayed Wotan in Wagner's Ring cycle and characters in 20th-century operas such as Alban Berg's Wozzeck and Lulu, and Reimann's Lear.
