beloved classic Doctor Who producer

TV Damn. Barry Letts, beloved classic Doctor Who producer, has died:

"Letts's legacy to the programme included the creation of the character Sarah Jane Smith, played by Elisabeth Sladen on the BBC to this day, and the decision to cast Tom Baker as the Fourth Doctor. The latter was a decision for which Tom Baker was always ready to express immense gratitude, as when Letts appeared on his episode of "This is Your Life" in the year 2000."

It's a massive legacy. Many of the creatives he hired or collaborated with would create the mythos of the show which is still being developed today.
