Pavel Ludikar (3 March 1882 – 19 February 1970) was a Czech operatic bass who had a highly successful international singing career from 1904 through 1944. He began his career in his native country and by 1911 had arisen at many of the major opera houses in Europe. From 1913 to 1935 his career was mainly centered in North and South America. The peak of his opera career was reached at the Metropolitan Opera in New York City, where he was committed from 1926 to 1932. He returned to Europe in 1935 to assume directorship of the Neues deutsches Theatre in Prague, remaining there until the theatre was closed in September 1938 due to Nazi occupation, effectively ending his stage career. The height of his later years in Prague was his portrayal of the title hero in the world premiere of Ernst Krenek's Karl V in June 1938.
One of the great singer-actors of his generation, Ludikar sang a broad repertoire of music which encompassed a total of twelve languages. He was particularly loved for his portrayals of roles in operas by Richard Wagner, Wolfgang Amadeus Mozart, and Giacomo Puccini. Ludikar began teaching singing in Prague in 1941. In 1947 he joined the faculty at the Vienna Music Academy, where he taught until his death almost three decades later. He also gave annual master classes at the Mozarteum University of Salzburg for many years. His voice is preserved on a number of recordings from the Supraphon label.
