Patrick TroughtonPatrick Troughton, the first actor to inherit the lead role of Doctor Who from another actor (and still one of the best-loved incarnations of the time-traveling Doctor), dies at the age of 67 on the second day of a science fiction convention in Columbus, Georgia. Despite worries about a persistent heart condition (he had already suffered heart attacks in 1978 and 1984), Troughton had made the trip to America against his doctor’s advice, suffering a fatal third heart attack after breakfast. His final TV appearance, the series Knights Of God, will air later in the year, having actually been filmed in 1985.
