Sir Donald Francis Tovey (1875-1940) was a musician, composer, conductor, writer and academic who was the Reid Professor of Music at Edinburgh University between 1914 and 1940.
One of his aims was to bring classical music to as wide an audience as possible. In 1917 he established the Reid Symphony Orchestra which gave eight public concerts a year for the rest of his life.
One of his best known works is the opera 'The Bride of Dionysius'. Listen to the Prelude here:
