Kenneth Mackenzie Clark, Baron Clark (13 July 1903 – 21 May 1983) was a British art historian, museum director and broadcaster. His expertise covered a wide range of artists and periods, but he is particularly associated with Italian Renaissance art, most of all that of Leonardo da Vinci. After running two art galleries in the 1930s and 1940s, he came to wider public notice on television, presenting a succession of programmes on the arts from the 1950s to the 1970s, the largest and best known being the Civilisation series in 1969.
The son of rich parents, Clark was introduced to the arts at an early age. Among his early influences were the writings of John Ruskin, which instilled in him the belief that everyone should have access to great art. After coming under the influence of the art experts Bernard Berenson and Roger Fry, Clark was appointed director of the Ashmolean Museum in Oxford aged twenty-seven, and three years later he was put in charge of Britain's National Gallery. His twelve years there saw the gallery transformed to make it accessible and inviting to a wider public. During the Second World War, when the collection was moved from London for safe keeping, Clark made the building available for a series of daily concerts which proved a celebrated morale booster during the Blitz.
After the war, and three years as Slade Professor of Fine Art at Oxford, Clark surprised many by accepting the chairmanship of the UK's first commercial television network. Once the service had been successfully launched he agreed to write and present programmes about the arts. These established him as a household name in Britain, and he was asked to create the first colour series about the arts, Civilisation, first broadcast in 1969 in Britain and in many other countries soon afterwards.
Among many honours, Clark was knighted at the unusually young age of thirty-five, and three decades later was made a life peer shortly before the first transmission of Civilisation. Three decades after his death, Clark was celebrated in an exhibition at Tate Britain in London, prompting a reappraisal of his career by a new generation of critics and historians. Opinions varied about his aesthetic judgement, particularly in attributing paintings to old masters, but his skill as a writer and his enthusiasm for popularising the arts were widely recognised. Both the BBC and the Tate described him in retrospect as one of the most influential figures in British art of the twentieth century.
Life and career
Early years
Clark was born at 32 Grosvenor Square, London, In several years he had the gallery opened two hours earlier than usual on the day of the FA Cup Final, for the benefit of people coming to London for the match.
Clark wrote and lectured during the decade. The annotated catalogue of the royal collection of Leonardo da Vinci's drawings, on which he had begun work in 1929, was published in 1935, to highly favourable reviews; eighty years later Oxford Art Online called it "a work of firm scholarship, the conclusions of which have stood the test of time". Another 1935 publication by Clark offended some in the avant-garde: an essay, published in The Listener, "The Future of Painting", in which he rebuked surrealists on the one hand and abstract artists on the other for claiming to represent the future of art. He judged both as too elitist and too specialised – "the end of a period of self-consciousness, inbreeding and exhaustion". He maintained that good art must be accessible to everyone and must be rooted in the observable world. During the 1930s Clark was in demand as a lecturer, and he frequently used his research for his talks as the basis of his books. In 1936 he gave the Ryerson Lectures at Yale University. From these came his study of Leonardo, published three years later; it too, attracted much praise, at the time and subsequently. Other important acquisitions, listed by Piper, were Rubens' Watering Place, Constable's Hadleigh Castle, Rembrandt's Saskia as Flora, and Poussin's The Adoration of the Golden Calf. He saw them in 1937 in the possession of a dealer in Vienna, The National Gallery in 2025 has two: The Adoration of the Kings, bought in 1884, and (The Sunset), bought in 1961.|group=n The trustees authorised the expenditure of £14,000 of public funds and the paintings went on display in the gallery with considerable fanfare.|group= n
Wartime
The approach of war with Germany in 1939 obliged Clark and his colleagues to consider how to protect the National Gallery's collection from bombing raids. It was agreed that all the works of art must be moved out of central London, where they were acutely vulnerable. One suggestion was to send them to Canada for safekeeping, but by this time the war had started and Clark was worried about the possibility of submarine attacks on the ships taking the collection across the Atlantic; he was not displeased when the prime minister, Winston Churchill, vetoed the idea: "Hide them in caves and cellars, but not one picture shall leave this island." A disused slate mine near Blaenau Ffestiniog in north Wales was chosen as the store. To protect the paintings special storage compartments were constructed, and from careful monitoring of the collection discoveries were made about control of temperature and humidity that benefited its care and display when back in London after the war. He set up the War Artists' Advisory Committee, and persuaded the government to employ official war artists in considerable numbers. There were up to two hundred engaged under Clark's initiative. Those designated "official war artists" included Edward Ardizzone, Paul and John Nash, Mervyn Peake, John Piper and Graham Sutherland. Artists employed on short-term contracts included Jacob Epstein, Laura Knight, L. S. Lowry, Henry Moore and Stanley Spencer.
Although the pictures were in storage, Clark kept the National Gallery open to the public during the war, hosting a celebrated series of lunchtime and early evening concerts. They were the inspiration of the pianist Myra Hess, whose idea Clark greeted with delight, as a suitable way for the building to be "used again for its true purposes, the enjoyment of beauty." There was no advance booking, and audience members were free to eat their sandwiches and walk in or out during breaks in the performance. The concerts were an immediate and enormous success. The Musical Times commented, "Countless Londoners and visitors to London, civilian and service alike, came to look on the concerts as a haven of sanity in a distraught world." 1,698 concerts were given to an aggregate audience of more than 750,000 people. Clark instituted an additional public attraction of a monthly featured picture brought from storage and exhibited along with explanatory material. The institution of a "picture of the month" was retained after the war, and, at 2025, has continued to the present day.
In 1945, after overseeing the return of the collections to the National Gallery, Clark resigned as director, intending to devote himself to writing. During the war years he had published little. For the gallery he wrote a slim volume about Constable's The Hay Wain (1944); from a lecture he gave in 1944 he published a short treatise on Leon Battista Alberti's On Painting (1944). The following year he contributed an introduction and notes to a volume on Florentine paintings in a series of art books published by Faber and Faber. The three publications totalled fewer than eighty pages between them.

In July 1946 Clark was appointed Slade Professor of Fine Art at Oxford for a three-year term. The post required him to give eight public lectures each year on the "History, Theory, and Practice of the Fine Arts". The first holder of the professorship had been Ruskin; Clark took as his first subject Ruskin's tenure of the post.
