and new scholarship and documentation introduced. Adrien Chappuis' The Drawings of Paul Cézanne – A Catalog Raisonné was published by Thames and Hudson in London in 1973 and has remained the classic source for the artist's graphic work. John Rewald continued Venturi's work after his death. Rewald was tasked with combining Venturi’s planned supplement with his own research, an agreement that did not work out as intended. After years of studying Cézanne’s works, Rewald found that he not only disagreed with many of his predecessor’s dates but a number of his attributions as well. He therefore set about developing an entirely new catalogue raisonné. Rewald's Paul Cézanne – The Watercolours: A Catalog Raisonné was published by Thames and Hudson, London with 645 illustrations in 1983. The missing dating of the paintings (Rewald only found one) and imprecise formulations of the pictorial motif such as Paysage or Quelques pommes caused confusion. In his early treatment of the Venturi Rewald made a list of all the works that could be dated without a stylistic analysis, because Rewald rejected such an analysis as unscientific. He continued his list by following the various whereabouts of Cézanne that could be verified by documents. Another scheme of his approach was to rely on the memories of the people portrayed, especially if they were Cézanne's contemporaries. Based on his own interviews, he made chronological assignments. Among the works that could be dated with certainty were Cézanne's Portrait of the Critic Gustave Geffroy, which the sitter confirmed as 1895, and Lake Annecy, which the artist visited only once, in 1896. Rewald died in 1994, he was not able to fully complete his work. When in doubt, Rewald's tendency was to include rather than exclude. This method was adopted by his closest associates, Walter Feilchenfeldt Jr., son of the art dealer Walter Feilchenfeldt, and Jayne Warman, who completed the catalog and provided it with introductions. The catalog was published in 1996 under the title The Paintings of Paul Cézanne: A Catalog Raisonne – Review. It includes the 954 works that Rewald wanted to record. Feilchenfeldt, Warman and David Nash went on to produce the first complete catalogue of the artist work since with The Paintings, Watercolours and Drawings of Paul Cézanne, an online catalogue raisonné.
