Edward Aneurin Williams (20 August 1921 – 8 December 2013) was a British composer known for his work on documentaries such as the Life on Earth series. With its avant-garde and pioneering music, using flute, harp, clarinet, strings, percussion and early synthesisers, Williams's Life on Earth score provided an evocative counterpoint to the visuals and Attenborough's commentary. Williams and his orchestra intricately crafted the music scene-by-scene to reflect the imagery on-screen. In one sequence examining the flight of birds, the instrumentation mirrors each new creature's appearance.
He also created the Soundbeam music system.
In 1996 he collaborated with Pip Eastop for a piece for the Arts Council of Great Britain.
Williams died on 8 December 2013.
