István Kertész was a Hungarian orchestral and operatic conductor who throughout his brief career led many of the world's great orchestras, including the Cleveland, Chicago, Philadelphia, New York, Los Angeles, Pittsburgh, Detroit, San Francisco and Minnesota Orchestras in the United States, as well as the London Symphony, Vienna Philharmonic, Berlin Philharmonic, Royal Concertgebouw Orchestra, Israel Philharmonic, and L'Orchestre de la Suisse Romande. His orchestral repertoire numbered over 450 works from all periods, and was matched by a repertoire of some sixty operas ranging from Mozart, Verdi, Puccini and Wagner to the more contemporary Prokofiev, Bartók, Britten, Kodály, Poulenc and Janáček. Kertész was part of a musical tradition that produced fellow Hungarian conductors Fritz Reiner, Antal Doráti, János Ferencsik, Eugene Ormandy, George Szell, János Fürst, Peter Erős, Ferenc Fricsay, and Georg Solti.

Béla Viktor János Bartók was a Hungarian composer, pianist and ethnomusicologist. He is considered one of the most important composers of the 20th century; he and Franz Liszt are regarded as Hungary's greatest composers. Through his collection and analytical study of folk music, he was one of the founders of comparative musicology, which later became known as ethnomusicology.
