After the war Wheldon joined the
Arts Council of Wales, and then in 1951 became the Arts Council's administrator for the
Festival of Britain, work for which he was appointed an
Officer of the Order of the British Empire (OBE) in 1952. In 1952, he joined the BBC as a publicity officer, but he was keen to make programmes, and he made his first appearance on television running a nationwide
conker competition, and subsequently became a familiar face on children's TV with his programme
All Your Own. Future
Led Zeppelin guitarist
Jimmy Page was a guest on his show in 1957 as part of the J.G.Skiffle Group. He also began to produce and present adult programmes, such as
Men in Battle with Sir
Brian Horrocks, and
Portraits of Power with
Robert McKenzie. He was also responsible for ''
Orson Welles' Sketchbook'' (1955). It was with the arts magazine programme
Monitor that Wheldon truly made his mark on the cultural scene. He was the editor of the programme – in the sense in which a newspaper has an editor – and he set about moulding a team of exceptional talents, including
John Schlesinger,
Ken Russell,
Humphrey Burton, and
Melvyn Bragg.
Monitor ranged in subject over all the arts: the hundredth show was
Elgar (1962), a film directed by Ken Russell and written by Wheldon, that celebrated the composer
Edward Elgar.
Monitor featured specially made films, sometimes just one full-length item, eventually using actors to re-enact the subjects' lives. Prior to this, only photos or location shots had been used in programmes. Wheldon's
Monitor lasted until he had "interviewed everyone I am interested in interviewing"; he was succeeded by
Jonathan Miller for the series' last season. In 1967, he was invited to deliver the MacMillan Memorial Lecture to the
Institution of Engineers and Shipbuilders in Scotland. He chose the subject "Perspectives on Television". Wheldon then entered BBC management, becoming Head of Documentaries. In 1968, he became the managing director of BBC television, a position he held until compulsory retirement in 1975. During this time he again gathered a team of the talents about him, promoting fellow programme makers such as
David Attenborough and
Paul Fox to high executive office, and the period of his administration included programmes such as ''
Dad's Army'',
Kenneth Clark's
Civilisation, ''
Alistair Cooke's America'', and
Jacob Bronowski's
The Ascent of Man (the last two were co-productions with
Time-Life Television). After he retired from management Wheldon co-wrote, with
J. H. Plumb, and presented
Royal Heritage, a ten-part series on the history of the British monarchy as expressed through the
Royal Collections. Produced by
Michael Gill, it achieved immense popularity ratings in 1977, the year of
the Queen's Silver Jubilee. Two other major documentaries followed,
The Library of Congress and
Destination D-Day. ==Later life==
