spilled forth his beloved jazz from well-traveled records. Visitors to this last studio seldom saw more than one or two new canvases, but found, often to their astonishment, that eight large compositions of colored bits of paper he had tacked and re-tacked to the walls in ever-changing relationships constituted together an environment that, paradoxically and simultaneously, was both kinetic and serene, stimulating and restful. It was the best space, Mondrian said, that he had inhabited. He was there for only a few months, as he died in February 1944. After his death, Mondrian's friend and sponsor in Manhattan, artist Harry Holtzman, and another painter friend, Fritz Glarner, carefully documented the studio on film and in still photographs before opening it to the public for a six-week exhibition. Before dismantling the studio, Holtzman (who was also Mondrian's heir) traced the wall compositions precisely, prepared exact portable facsimiles of the space each had occupied, and affixed to each the original surviving cut-out components. These portable Mondrian compositions have become known as "The Wall Works". Since Mondrian's death, they have been exhibited twice at Manhattan's Museum of Modern Art (1983 and 1995–96), once in SoHo at the Carpenter + Hochman Gallery (1984), once each at the Galerie Tokoro in Tokyo, Japan (1993), the XXII Biennial of Sao Paulo (1994), the University of Michigan (1995), and – the first time shown in Europe – at the Akademie der Künste (Academy of The Arts), in Berlin (22 February – 22 April 2007). His work was also shown in a retrospective exhibition at the Whitechapel Gallery in London, which ran from August – September 1955. Death and legacy Piet Mondrian died of pneumonia on 1 February 1944 and was interred at the Cypress Hills Cemetery in Brooklyn, New York. On 3 February 1944 a memorial was held for Mondrian at the Universal Chapel on Lexington Avenue and 52nd Street in Manhattan. The service was attended by nearly 200 people including Alexander Archipenko, Marc Chagall, Marcel Duchamp, Fernand Léger, Alexander Calder and Robert Motherwell. The Mondrian / Holtzman Trust functions as Mondrian's official estate, and "aims to promote awareness of Mondrian's artwork and to ensure the integrity of his work". Mondrian was described by critic Robert Hughes, in his 1980 book The Shock of the New, as "one of the supreme artists of the 20th century." Likewise in his television documentaries of The Shock of the New,
