Dr. David Keel which role was performed by Ian Hendry, born on 13 January 1931 at Ipswich, England and passed away on December 24, 1984 London, was in fact the first partner of John Steed and so played in the first season.. Except for Mike Gambit in the New Avengers he was the only male partner of Steed. I don't know much about his character, sorry for that!
