Just noticed that the site has a "Hungarians in Hollywood" section and refers to Rozsa as follows:
Miklós Rózsa - Triple Oscar winning film composer - Rózsa is credited with the film scores of such classics as The Thief of Baghdad (1940), The Jungle Book (1942), Spellbound (1945), Julius Caesar (1953), Ben-Hur (1959) and El Cid (1961). Rózsa's best-known concert work is the orchestral Theme, Variations and Finale, op. 13, which was on the program when Leonard Bernstein made his conducting debut.
