Dudley Simpson, the Australian-born veteran BBC composer whose sound defined Doctor Who in the 1960s and ’70s, as well as such series as Blake’s 7, The Tomorrow People, Moonbase 3, and many others, dies at the age of 95. Simpson scored his first Doctor Who serial, the second season opener Planet Of Giants, in 1964 at a time when the series often relied on stock music. He solidified his position as Doctor Who’s house composer during the Troughton era, scoring pivotal stories such as The Evil Of The Daleks, The Ice Warriors and The War Games, and became the dominant musical sound of the series during the Pertwee and Tom Baker eras, during which he provided all but a handful of original scores and stock music fell by the wayside. It was only when incoming producer John Nathan-Turner took over as Doctor Who’s showrunner in 1980 that Simpson’s Doctor Who tenure ended. He retired to Australia in the 1990s.
