“With an apple I will astonish Paris,” said Paul Cézanne, the artist who painted the path from 19th-century Impressionism to 20th-century Cubism. Indeed, his apples do seem to possess secrets from the Tree of Knowledge, some of them cooly cerebral, others blushing. This exhibition explores Cézanne’s unparalleled influence on fellow artists from the 19th and 20th centuries, among them the painters Chardin and Corot, Picasso, Braque, and Matisse. Cézanne is the magnetic center, the man who connected artists across time. —E.C.
