Nicholas Courtney, Brigadier Alistair Gordon Lethbridge-Stewart in both Doctor Who and The Sarah Jane Adventures, sadly passed away earlier this week at the age of 81.
He will be remembered as a stalwart of Doctor Who particularly in the Jon Pertwee era when he was in more stories than not. He was a regular at conventions and I met him myself at an event in Liverpool in 2002 where he came across, as he always did, as a lovely man with plenty of stories to tell who could keep you entertained for hours.
