Arno Breker, 90, a sculptor and portrait painter whose reputation was tainted by his work for the Nazis, died Wednesday in Dusseldorf, Germany. After early experiments with abstraction, he turned to portraiture in the 1920s, when he was living in Paris. In 1938, he was named a professor at the Academy of Art in Berlin. He earned commissions from the Nazis to beautify the capital of the Third Reich and worked closely with Albert Speer, the architect convicted as a war criminal. After the war, when museums refused to exhibit his works, he maintained that he helped such friends as Pablo Picasso and Jean Cocteau by intervening with Nazi officials and saving them from arrest.
Ellis P. Leonard, 86, professor emeritus of veterinary surgery at Cornell University's Veterinary Medical Teaching Hospital, died Feb. 7 in Ithaca, N.Y. He wrote several textbooks and pioneered methods of treating fractures in small animals.
Marcel Tolkowsky, a Belgian-born gemologist and mathematician who developed the symmetry for cutting diamonds for maximum brilliance, died Sunday in New York. He was 92. In 1919, as part of his doctoral thesis at the University of London, he developed a mathematical formula for cutting and angling facets on diamonds to provide maximum reflected light and optimum brilliance. The process, which called for cutting 58 facets on a diamond, came to be known as the "ideal cut."
