Léonard Tsuguharu Foujita (藤田 嗣治 Fujita Tsuguharu, November 27, 1886 – January 29, 1968) was a Japanese–French painter and printmaker born in Tokyo, Japan, who applied Japanese ink techniques to Western style paintings. He has been called "the most important Japanese artist working in the West during the 20th century". His Book of Cats, published in New York by Covici Friede, 1930, with 20 etched plate drawings by Foujita, is one of the top 500 (in price) rare books ever sold, and is ranked by rare book dealers as "the most popular and desirable book on cats ever published".
On his return to France, Foujita converted to Catholicism. He was baptised in Reims Cathedral on 14 October 1959, with René Lalou (the head of the Mumm champagne house) as his godfather and Françoise Taittinger as his godmother. This is reflected in his last major work,at the age of 80, the design, building and decoration of the Foujita Chapel in the gardens of the Mumm champagne house in Reims, France, which he completed in 1966, not long before his death. Tsuguharu Foujita died of cancer on January 29, 1968, in Zürich, Switzerland and was interred in the Cimetière de Villiers-le-Bâcle, Essonne département, France. In 2003, his coffin was reinterred at the Foujita Chapel under the flagstones in the position he originally intended when constructing the chapel.
