Dieter Gerhard Mamlok (Hamburg, December 16, 1923 – New York, September 20, 2005) survived the Holocaust as a young refugee sheltered by foster parents in Sweden. In 1945, he immigrated to the United States where he established an import/export business. He married Ursula Lewy in 1947 and from then on, and throughout the rest of his life, he supported her work as a composer.
Art was his own passion. He took photographs and wrote short stories and novellas. Funds from his estate endowed the creation of the Dwight and Ursula Mamlok Foundation, which the composer, who outlived her husband by eleven years, had made provision to set up during her own lifetime.
