Jan Boleslav Sedivka AM (8 September 1917 – 23 August 2009) was widely recognised as one of Australia's leading violinists and teachers.
Educated in the Czech Republic (Otakar Ševčík, Prague Conservatoire, J. Kocian), France (École Normale de Musique, Classe Jacques Thibaud) and England (Max Rostal), he made his reputation overseas as a soloist, chamber music player and teacher before coming to Australia in 1961.
As a performer, Jan Sedivka gained special merit for his efforts on behalf of Australian contemporary music. In this capacity he introduced a number of important works dedicated to him, in particular concertos by Larry Sitsky (Nos. 1, 2, 3 & 4), James Penberthy, Ian Cugley, Don Kay, Colin Brumby, Edward Cowie and Eric Gross.
His wife Beryk Sedivka is a noted pianist who often performed with him.
