Thomas Stewart grew up in San Saba, Texas, and was trained in music, drama, and electronics before leaving for New York in the 1950s. There he studied at the Julliard School, met and married soprano Evelyn Lear, and began his singing career. After Fulbright scholarships took the Stewarts to Berlin in 1957, he began a long association with the Deutsche Oper Berlin and with the German operatic repertory. He began singing the great Heldenbaryton roles at Bayreuth in 1960. He sang all of the leading Wagnerian parts at Bayreuth and in the leading opera houses of the world over the next decades with particular success in the roles of Wotan in The Ring and Hans Sachs in Die Meistersinger von Nuernberg. He and Evelyn Lear are now retired to the Washington area where they are active on the musical scene. He appeared in the speaking part of Pasha Selim in the Washington Opera's 1999 production of Mozart's Die Entfuehrung aus dem Serail (The Abduction from the Seraglio).
