was removed from the Austrian commercial register on May 31, 1939. Both men subsequently emigrated to London, where they reestablished the imprint as the Phaidon Press as one of the leading British art book publishers. In 1955, during a stay in New York, Horovitz suffered a sudden heart attack and died at the age of 56, upon which the leadership at Phaidon was assumed by his son-in-law, Harvey Miller. A decade later, in 1967, Phaidon was acquired by Frederick A. Praeger Inc, a subsidiary of Encyclopædia Britannica. Goldscheider remained director of the Phaidon Press until his own death in London in 1973. From 1974 to 1981, Phaidon was owned by Elsevier, when it was sold in a management buyout under the name Musterlin. It was acquired by entrepreneur Richard Schlagman in 1990 and its headquarters returned to London in May 1991. Schlagman then hired renowned designer Alan Fletcher in 1993 to be the creative lead. In 1998, Fletcher brought on board the German designer Julia Hasting, who began focusing on conceptual book design, emphasizing the art book as an object. This approach was translated into the architecture and photography books, as well as the cookery program. Phaidon acquired the online art-sales business Artspace. In January 2020, it acquired the publishing house The Monacelli Press from its founder. Publishing categories Architecture Phaidon publishes monographs on the work of twentieth-century masters including Marcel Breuer, Le Corbusier, Mies van der Rohe, Alvar Aalto, and Eero Saarinen. It also publishes monographs on contemporary international architecture practices, for example on Tadao Ando, Peter Marino, John Pawson, MAD, and Snøhetta. Phaidon also publishes historical and geographical surveys on architecture. In 2004, it published the giant format Atlas of Contemporary World Architecture, followed by The Phaidon Atlas of 21st Century World Architecture, Atlas of Brutalist Architecture, and Atlas of Mid-Century Modern Houses. Art Phaidon also publishes monographs on established and emerging artists, as well as surveys of contemporary and historical art movements and genres.
