Tony Whitby

[5] Whitby was born in Mere, Wiltshire and was educated at Bristol Cathedral School, where he won a scholarship to St Edmund Hall, Oxford.

[6] In this post, he gained a reputation for shrewdly picking out the ideas of others and embellishing them by adding his own thoughts and suggestions.

He had no intention of creating a new schedule from scratch, but he wanted a more topical and a more varied flavour - to make Radio 4, in his words, like a "well-labelled library that has a few surprises in it".

[7] In 2010, David Hendy, lecturer in broadcasting history at the University of Westminster, said: "Looking back, what's most striking about Whitby's revolution of 1970 is how genuinely eclectic it made Radio 4, with programmes stretching across a suddenly wider spectrum, from the intellectually demanding or disturbing at one end to the faintly scurrilous or comforting at the other.

The changes 40 years ago set Radio 4 on its long-term trajectory: away from the dusty tones of the somewhat middlebrow old Home Service, to the tougher, livelier, more authoritative, network we have today".
