The BBC television science-fiction series Doctor Who, which will celebrate its fiftieth anniversary next year, owes its longevity in great part to a very clever device the writers dreamt up decades ago – when the Doctor is close to death he can regenerate into a brand new body. This has allowed a series of completely different actors to play our hero over the years, from the 1960s when William Hartnell as the First Doctor changed into the Second Doctor played by Patrick Troughton, right through to the present day and Doctor number Eleven as played by the rather wonderful Matt Smith.
Whilst Tom Baker, the Fourth Doctor may not be the very first Doctor I remember – that honour goes to his predecessor Jon Pertwee – the wonderfully eccentric and flamboyantly dressed Baker is certainly the Doctor I recall best from my childhood.
