Miranda Carter looks at the life and career of Kenneth Clark, the centenary of whose birth falls this month.
Clark was the youngest-ever Director of the National Gallery, an art historian of brilliance who communicated his passion to the public in a way nobody had before.
His television series, Civilisation, was a landmark in broadcasting, a programme of high seriousness and ambition which reached a mass audience.
Yet this gifted communicator was a socially awkward man whose reticence led him to resign from nine clubs.
The populist broadcaster was also a man with a reputation for snobbery.
Miranda Carter talks to those who knew Clark and those touched by his legacy, including the broadcaster Sir David Attenborough and two of his successors at the National Gallery, Neil MacGregor and Charles Saumarez-Smith.
