Leon Kossoff, whose expressionistic portraits and images of urban life made him one of the most important painters of post-war Britain, died on July 4 in London. He was 92.

His main subjects were his family and friends, or models who became friends, also the many glories of London — its pedestrians, its streets, its railway and underground stations and their trains — and old master paintings in the National Gallery. In 1957, he had his first solo show with Beaux Arts. In 1981, he showed his work for the first time in the United States in an exhibition of figurative painting from Britain at the Yale Center for British Art; two years later, he had his first solo show at the Hirschl & Adler Gallery in New York. The Tate Gallery staged a retrospective in 1996, and in 2007, the National Gallery organized “Leon Kossoff: Drawing From Painting,” bringing together a large selection of his drawings of its masterpieces.
