And now about Lucien Freud:
Freud’s two legitimate children, by his first wife, Kitty Garman (an illegitimate daughter of the sculptor Sir Jacob Epstein), are his daughters Annie Cornet and Annabel Stirk. But the painter has recognized six others as his own. They include four offspring by Suzy Boyt, a former Slade School of Fine Art student with whom Freud was involved in the late 50s and early 60s: a son, Alexander (“Ali”) Boyt, now a banker, and daughters Isobel (“Ib”) Boyt, Rose Boyt (the novelist), and Suzy Boyt. (Freud considers musician Kai Boyt, another child of Suzy’s, to be his stepson.)
Then, by Bernardine Coverley, with whom Freud began a relationship in the early 60s, he fathered Bella Freud (now a fashion designer and winner of the British Fashion Council’s 1991 award for best young talent) and, two years later, Esther Freud, another novelist.
Freud has done pictures of all his acknowledged children over the years, and though that is commonplace, his practice of painting his grown daughters in the nude certainly is not. Nor are the girls posed in graceful art-school compositions. Splayed legs and exposed labia are common themes in his oil paintings of Annabel, Esther, and Rose. Unremittingly graphic is Freud’s 1980–81 canvas of Annabel. The pregnant woman, who was 28 at the time, is shown zonked-out on a tattered sofa, her distended stomach and swollen breasts branched with blue veins—a puzzling act of paternal attention.
