Georg Hajdu (born June 21, 1960 in Göttingen, West Germany) is a German composer of Hungarian descent. His work is dedicated to the combination of music, science and computer technology. He is noted for his opera and the network music performance environment .
Hajdu was born to Hungarian parents who had fled their country in 1956. He grew up in Cologne where he obtained diplomas in molecular biology and musical composition from the University of Cologne and the Cologne Musikhochschule, resp. A stipend by the German Academic Exchange Service enabled him to enter the graduate program in composition at the University of California, Berkeley in 1990, working closely with the Center for New Music and Audio Technologies (CNMAT) and eventually obtaining a Ph.D. in 1994. His teachers include Georg Kröll, Johannes Fritsch, Krzysztof Meyer, Clarence Barlow, Andrew Imbrie, Jorge Liderman and David Wessel. He also audited classes with György Ligeti in Hamburg.
In 1996, following residencies at IRCAM and the ZKM, Karlsruhe, he co-founded the Ensemble WireWorks with his wife, pianist Jennifer Hymer—a group specializing in the performance of mixed-media composition. In 1999, he produced his full-length opera for which author and film director wrote the libretto. In May 2002, his interactive networked performance environment was employed in a Munich Biennale opera performance. In 2004, he instigated the development of the Bohlen–Pierce clarinet and in 2005 he co-founded the European Bridges Ensemble for networked music performance.
