Adolf Dauber (known also as Dol, Doli or Dolfi Dauber) (born 27 July 1894 – died 15 September 1950) was a jazz violinist, bandleader, composer and music arranger of Jewish origin, who was active in the first half of the 20th century in Central Europe, mainly in Austria, Czechoslovakia and Germany. During his career, he collaborated with international jazz personalities, led numerous orchestras and ensembles, and created music for several films.
Dauber was born to a musical family in Vyzhnytsia (Wijnitz), Bukovina, Ukraine (then Austria-Hungary). He started his musical education at the age of 4, under the mentorship of his older sister, Clara. While still in his childhood, his sister arranged an audience with Carl Flesch, a violin virtuoso and teacher at the Bucharest Conservatory. His talent impressed Flesch and Dauber joined his class as the youngest pupil to be accepted.
In 1911, Flesh recommended him to the renowned Czech violinist and teacher, Otakar Ševčík. Dauber studied with Ševčík in Brno up to 1914. Even as a youngster, he earned money for his studies as a bandleader of ensembles in Chernivtsi (Czernowitz) and Lviv.
During World War I, he served as a concertmaster and soloist in a military orchestra in Italy. The opera composer Giacomo Puccini was allegedly so impressed by his playing that he dedicated to him several autograph pages from his opera Manon Lescaut. Later, Franz Lehár arranged his transfer to the renowned Austro-Hungarian military ensemble Deutschmeister.
