A passionate collector, Neumann amassed more than 200 art works in his Vienna villa. He escaped Austria after the Nazi annexation via Switzerland to Paris. When the Nazis occupied France, he fled by foot through the Pyrenees to Spain. From there he reached Cuba, where he settled, and participated in the 1954 founding of an art museum in Havana. He later moved to New York to be with his daughter, and died there in 1961, age 82. Neumann's artworks were seized by the Nazis, then released shortly afterward to allow a sale to the Kunsthistorisches Museum in Vienna. Neumann's daughter sold the altar panels in 1938. The money went into a frozen account to pay Neumann's "emigration tax."
