Origins and activities 
Vilmos Tátrai (1912-1999), Professor in the Franz Liszt Academy of Music, founded the quartet in 1946 with leading members of the Budapest Capital Orchestra, later called the Hungarian State Concert Orchestra. Mihály Szűcs was concertmaster of the State Opera House, György Konrád was solo violist of the State Concert Orchestra, and Ede Banda was a professor at the Academy of Music and solo cellist of the State Concert Orchestra. The quartet won first prize at the Bartók String Quartet Competition in 1948. Tátrai soon afterwards took the first violin desk at the Hungarian State Orchestra and was still occupying it in 1982. In 1957 Tátrai founded the Hungarian Chamber Orchestra, which has no conductor, and remained its leader for more than two decades. The quartet was awarded the Kossuth Prize in 1958. By 1982 it had given the first performances of 72 Hungarian works and the Hungarian premieres of 64 works by foreign composers. The group had a repertoire of over 300 works and a history of more than 2000 performances. Their (more than 72) recordings on the Hungaroton, Telefunken, and Muza labels include extensive surveys of Beethoven, Bartók, Mozart and Haydn. Sources
