Dajos Béla (birth name Leon Golzmann, 19 December 1897 – 5 December 1978) was a Russian violinist and band-leader.
Golzmann was born in Kiev, now part of the Ukraine, of a Russian father and Hungarian mother. He served as a soldier during World War I, after which he studied music in Moscow. He then continued his studies in Berlin, where he started playing in local venues. He was contacted by Carl Lindström AG to make recordings and started his own salon orchestra, at which period he changed his name to the more Hungarian-sounding Dajos Béla, Hungarian or Roumanian music then being popular in Germany. Along with those of Paul Godwin and Marek Weber, his orchestra became one of the most popular in Germany and gained a high reputation abroad. He played a range of music, but for jazz music often recorded under different names, such as The Odeon Five, Mac’s Jazz Orchestra and the Clive Williams Jazzband.
As soon as the Nazis came to power in Germany in 1933 Béla, who was Jewish, started touring abroad. In 1935 he travelled to Buenos Aires, where he remained for the rest of his life. He died in La Falda, Argentina, in 1978.
