Růžička, Rudolf , Czech composer and pedagogue; b. Brno, April 25, 1941. After attending the Brno Cons. (1958–62), he studied composition with Theodor Schaefer and Miloslav Ištvan (1962–67) and Miloslav Kabelàč (1967–69) at the Janàček Academy of Music and Dramatic Arts (1967–69). In 1969 he joined the faculty of the latter, where he taught courses in electroacoustic and computer composition. As a prominent figure in avant-garde circles, Růžička became suspect in the eyes of the rigid Communist regime. All the same, he persevered in his activities with various avant-garde groups at home and abroad. In 1970 his Gurges won 1st prize in the Musica Nova competition in Brno and in 1984 his Tibia I received 1st prize in the Marcel Josse competition in Paris. Following the collapse of the Communist regime in 1989, Růžička assumed an even greater prominence among the avant-garde of his homeland and abroad. While he has composed various works in the traditional genres, he has become best known for his use of computers in producing innovations in the forms and structures of his works.
