My friend Edward Williams, who has died aged 92, was a composer of music for film and television and a pioneer of electronic music. One of the films he wrote the music for, the documentary Dylan Thomas (1961), directed by Jack Howells and narrated by Richard Burton, won an Oscar in 1963.
His innovative combination of electronic and instrumental music led to his being commissioned for David Attenborough's 1979 natural history series Life on Earth and he provided the thrilling soundtrack for a number of dramas and documentaries that I directed in the 1970s, 80s and 90s. The BBC series Excalibur – the Search for Arthur won him the best music award at Bafta Cymru's award event in 1996.
