Richard Cassilly

Richard Cassilly was an American operatic tenor who had a major international opera career between 1954–90. Cassilly "was a mainstay in the heldentenor repertory in opera houses around the world for 30 years", and particularly excelled in Wagnerian roles like Tristan, Siegmund and Tannhäuser, and in dramatic parts that required both stamina and vocal weight, such as Giuseppe Verdi's Otello and Camille Saint-Saëns's Samson.
