National Gallery
In 1933 the director of the National Gallery in London, Sir Augustus Daniel, was aged sixty-seven, and due to retire at the end of the year. His assistant director, W. G. Constable, who had been in line to succeed him, had moved to the new Courtauld Institute of Art as its director in 1932. The historian Peter Stansky writes that behind the scenes the National Gallery "was in considerable turmoil; the staff and the trustees were in a state of continual warfare with each other." The chairman of the trustees, Lord Lee, convinced the prime minister, Ramsay MacDonald, that Clark would be the best appointment, acceptable to the professional staff and the trustees, and able to restore harmony. When he received MacDonald's offer of the post, Clark was not enthusiastic. He thought himself too young, aged 30, and once again felt torn between a scholarly and an administrative career. He accepted the directorship in January 1934, although, as he wrote to Berenson, "in between being the manager of a large department store I shall have to be a professional entertainer to the landed and official classes".At about the same time as accepting MacDonald's offer of the directorship, Clark had declined one from King George V's officials to succeed C. H. Collins Baker as Surveyor of the King's Pictures. He felt that he could not do justice to the post in tandem with his new duties at the gallery. The King, determined to succeed where his staff had failed, went with Queen Mary to the National Gallery and persuaded Clark to change his mind. The appointment was announced in The London Gazette in July 1934; Clark held the post for the next ten years.
Clark believed in making fine art accessible to everyone, and while at the National Gallery he devised many initiatives with this aim in mind. In an editorial, The Burlington Magazine said, "Clark put all his insight and imagination into making the National Gallery a more sympathetic place in which the visitor could enjoy a great collection of European paintings". He had rooms re-hung and frames improved; by 1935 he had achieved the installation of a laboratory and introduced electric lighting, which made evening opening possible for the first time. A programme of cleaning was begun, despite sporadic sniping from those opposed in principle to cleaning old pictures; experimentally, the glass was removed from some pictures. 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.
The Burlington Magazine, looking back at Clark's time at the gallery, singled out among the works acquired under his leadership the seven panels forming Sassetta's San Sepolcro Altarpiece from the fifteenth century, four works by Giovanni di Paolo from the same period, Niccolò dell'Abate's The Death of Eurydice from the sixteenth century and Ingres' Madame Moitessier from the nineteenth. 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.
One of Clark's least successful acts as director was buying four early-sixteenth century paintings now known as Scenes from Tebaldeo's Eclogues. He saw them in 1937 in the possession of a dealer in Vienna, and against the united advice of his professional staff he persuaded the trustees to buy them. He believed them to be by Giorgione, whose work he considered inadequately represented in the gallery at the time. The trustees authorised the expenditure of £14,000 of public funds and the paintings went on display in the gallery with considerable fanfare. His staff did not accept the attribution to Giorgione, and within a year scholarly research established the paintings as the work of Andrea Previtali, one of Giorgione's minor contemporaries. The British press protested at the waste of taxpayers' money, Clark's reputation suffered a considerable blow, and his relations with his professional team, already uneasy, were further strained.
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.
With an empty gallery to preside over, Clark contemplated volunteering for the Royal Naval Volunteer Reserve, but was recruited, at Lord Lee's instigation, into the newly formed Ministry of Information, where he was put in charge of the film division, and was later promoted to be controller of home publicity. 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.
