Exhibitions of the week: R B Kitaj: Obsessions, various venues

Powerful picture: If Not, Not, 1975 (R.B. Kitaj Estate/National Galleries of Scotland )

How Jewish was the art of R B Kitaj, one of the leading lights of postwar British art, who became so upset by the critical mauling he got that he left the country for his native America?

Two galleries join forces to make the case for this nervy and at times wayward member of the group that refreshed figurative art in London after the war.

Featuring some powerful pictures (including If Not, Not, pictured above), London focuses on his self-proclaimed Jewishness; the other, in Chichester, on an overview of his career, including some affectionate portraits.

Jewish Museum, London NW1 (020 7284 7384) to 16 Jun; Pallant House Gallery, Chichester (01243 774557) to 16 Jun
