Aurélio Buarque de Holanda Ferreira (May 3, 1910 – February 28, 1989) was a Brazilian lexicographer, philologist, translator, and writer, best known for editing the Novo Dicionário da Língua Portuguesa, a major dictionary of the Portuguese language. His family name was originally spelled Hollanda, but was changed to Holanda, presumably to follow the Portuguese spelling reform of 1943. Source: Wikipedia (en)
