Geoffrey Simon (born 3 July 1946) is an Australian conductor resident in London.
Geoffrey Simon was born on 3 July 1946 in Adelaide. He was a student of Herbert von Karajan, Rudolf Kempe, Hans Swarowsky and Igor Markevitch, and a major prize-winner at the first John Player International Conductors' Award. He has made 45 recordings for a number of labels, combining familiar works with world premieres of rediscovered obscure works by Tchaikovsky, Respighi, Borodin, Mussorgsky, Smetana, Grainger, Debussy, Ravel, Saint-Saëns and Les Six.
For his own label, Cala Records, Geoffrey Simon has a series of records where he has brought together ensembles of single instruments—all violins, violas, cellos, double basses, horns, trumpets, trombones and harps—drawn from London's leading solo and orchestral musicians. The recordings have attracted interest among instrumentalists, composers and audiences worldwide.
He has appeared in London with the London Philharmonic Orchestra, London Symphony Orchestra, Philharmonia Orchestra, Royal Philharmonic Orchestra, London Chamber Orchestra and English Chamber Orchestra.
