Armand Castelmary was a member of the Paris Opera from 1863 to 1870, where he created the three significant roles in the French grand operas listed above. He was married (later divorced) to the soprano Marie Sass, who created the role of Élisabeth in Verdi's Don Carlos. He made his debut at the Royal Opera House, London, in 1889 and sang there in many subsequent seasons. Castelmary toured the United States with several different opera companies in 1870, 1879 and 1890 and made his debut at the Metropolitan Opera in New York in 1893. He died onstage at the Metropolitan Opera in New York during a performance of Flotow's Martha. The audience, not realising he was suffering a heart attack, thought his physical collapse was a stroke of fine acting and rewarded him with a loud ovation as the curtain was lowered.
