Lauritz Melchior was a Danish-American opera singer. He was the preeminent Wagnerian heldentenor of the 1920s, 1930s, and 1940s and has come to be considered the quintessence of his voice type. Late in his career, Melchior appeared in movie musicals and on radio and television. He also made numerous recordings.

A heldentenor, earlier called tenorbariton, is an operatic tenor voice, most often associated with Wagnerian repertoire.
