Freud was a great divider. He allowed few of us to see any of the others. The central crossroads in his later life were his painting studio and Clarke’s. Everyone important to him in his final years met there.

He was entrenched in life-study portraiture and he made it provocative. ‘It is the only point of getting up every morning: to paint, to make something good, to make something even better than before, not to give up, to compete, to be ambitious,’ he said.

He was often virtually penniless in his early days, spending almost all his money on paint. ‘Until I was fifty I never had a bank account, always lived from hand to mouth. I used to lie awake at night wondering if I’d be able to go on with my paintings or whether the paint would run out.

The end of Lucian’s gambling days coincided with gaining a new dealer. William Acquavella was ambitious, and transformed Lucian’s reputation and prices. His New York gallery was the ultimate blue-chip modern art dealership, presenting exhibitions by Monet, Degas, Cézanne, Picasso and Léger.

D’Offay’s relationship with Freud had started in the 1960s through an introduction by a bright young art expert called James Kirkman, the son of a general, who worked for Marlborough Fine Art and looked after Lucian there. Marlborough, part-owned by the Duke of Beaufort, was the most prestigious British contemporary gallery, representing Francis Bacon, Henry Moore and Graham Sutherland, as well as Lucian. But Lucian felt ignored and sidelined compared to his friend Bacon, who in 1962 had a show at the Tate Gallery and was rapidly gaining a global reputation. ‘Lucian was by no means a star then. He was actually thought to be something of a has-been,’ said Kirkman. ‘No one was really interested in figurative art, especially what he did. Pop art and kinetic art was what modern art collectors desired. All that passed Lucian by, making him seem traditional, even old-fashioned, but still with an ability to shock with his raw nudes. He was doing pictures that were considered less attractive, that were not really appealing to anyone. It sounds strange now but that was the reality and how he was received and perceived.
