4495 Dassanowsky           Discovered 1988 Nov. 6 by M. Arai and H. Mori at Yorii.
Austrian-born film pioneer, Elfi Dassanowsky (1924-2007) co-founded the Belvedere Film studio in Vienna at age 22. A piano prodigy, she was a stage actor and singer following her postwar opera debut. A Hollywood vocal coach in the 1960s, she later returned to film production, arts promotion and humanitarian efforts.
