Stage actor Patrick took over the role in 1966.
He also played the role for three years until 1969.
Patrick's regeneration storyline occurred in the ten-episode arc War Games where the Doctor's fellow Time Lords pre-empt his next transformation as punishment for his adventuring.
In his own words, Patrick explained that “Three years was long enough.
"I didn't want to get typecast, and one had to get out while the going was good.”
He also returned for the tenth season opener, The Three Doctors, along with his predecessor and successor.
And he returned for The Two Doctors in 1985, along with sixth Doctor, Colin Baker.
Lost episodes from his stint as the Doctor were rebooted in 2020 – and he even got the cartoon treatment.
His other TV work includes playing Robin Hood in the 1953 TV mini series of the same name, George Barton in Coronation Street (1974) and Perce in The Two Of Us (1986)
His movies include The Omen, in which he played Father Brennan, and Klove in Scars Of Dracula.
Patrick died on March 28, 1987, at the age of 67.
