On this day one hundred years ago William Hartnell, the very first actor to play Doctor Who, was born.
It's incredible to realise that the series came at the end of quite a successful acting career for Hartnell and there are many fans of the series who have only seen him in it and also Carry On Sergeant. But even today his performances shine through.
And in many ways he was the man who made the series work in its early years, when few in the BBC reportedly had faith in its longevity. Even today some of his stories can be found amongst those most cherished by fans.
