Richard Cassilly (December 14, 1927 – January 30, 1998) was an American operatic tenor who had a major international opera career between 1954 and 1990. 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". He was also an admired Don José in Carmen and sang almost all of the leading Puccini tenor roles. Standing at 6 foot 3 and possessing a 250-pound frame The New York Times described him as "a burly tenor with a bright ping on the top notes who had a supple lyric quality [to his voice]", and "was known to bring a musical intelligence and uncommonly clear diction to his work."
Cassilly spent the early years of his opera career singing primarily with the New York City Opera between 1955–1966, often portraying roles in obscure and contemporary operas. During these years he also traveled frequently throughout North America, appearing with most of the major opera companies in the United States and Canada. In 1965 he launched a major international opera career when he portrayed the title role in a critically acclaimed production of Heinrich Sutermeister's Raskolnikoff at the Grand Théâtre de Genève. This performance earned him a contract with the Hamburg State Opera as their leading in-house dramatic tenor, a position he held from 1965-1978. Engagements with other major companies soon followed, and by 1973 Cassilly had sung leading roles with almost every major opera house in Europe, including La Scala, the Opéra National de Paris, the Vienna State Opera, and the Bavarian State Opera. Cassilly also forged a strong collaborative partnership with the Royal Opera in London, appearing in that house almost every year from 1968-1982. In 1978 he joined the roster of principal tenors at the Metropolitan Opera in New York City, where he spent the majority of his time until his retirement in 1990.
Education and early career 
Born in Washington, D.C., Cassilly spent his childhood on a farm near Aberdeen, Maryland before moving to Baltimore, Maryland with his family in his early teens. He first became involved in music through singing in his high school's glee club. In 1946, at the age of eighteen, he entered the Peabody Conservatory at Johns Hopkins University where he studied singing with Hans Heinz. As a student he sang in college productions of The Flying Dutchman (as the Steersman) and Madama Butterfly (as Pinkerton). During this time he also had the opportunity to study under Rosa Ponselle who had retired from her career and was residing in Baltimore.
After graduating with a degree in vocal performance in 1952, Cassilly moved to New York City with his first wife and their first child to pursue a performance career. Shortly thereafter he became a member of the John Harms Chorus singing with them at such venues as Town Hall between 1952-1954. He also worked as a paid singer for a couple of different churches during this time. Eventually his break came in 1954 when he was hired by William Steinberg as the tenor soloist in Beethoven's Symphony No. 9 with the Pittsburgh Symphony. This was followed by his operatic debut on Broadway as A Young Man and understudy for Michele in Gian Carlo Menotti's The Saint of Bleecker Street in December 1954. The production was a particular hit with the New York public and ran through April 1955. After it closed, the NBC Opera Theatre decided to use the cast for a televised version of the show.
American fame and the New York City Opera years:1955-1966 
Cassilly's performance in The Saint of Bleecker Street drew the attention of Joseph Rosenstock, director of the New York City Opera (NYCO), who invited him to audition for the company in the Spring of 1955. Impressed with the audition, Rosenstock offered him a contract with the company and Cassilly made his NYCO debut in the title role of Tchaikovsky's Cherevichki (performed under the title The Golden Slipper) opposite Beverly Sills as Oxana on October 13, 1955.
Cassilly sang regularly at the NYCO in productions through 1966, often in contemporary operas or in rarely heard works. He notably sang in several American premieres with the company including Ferdinand in Frank Martin's The Tempest in 1957 and the Jailer in Luigi Dallapiccola's Il prigioniero, with Norman Treigle and Leopold Stokowski, in 1960.
