Neumann (pronounced [ˈnɔʏman] ) is a German surname, with its origins in the pre-7th-century (Old English) word neowe meaning "new", with mann, meaning man. The English form of the name is Newman. Von Neumann is a variant of the name, and alternative spellings include Neuman, Naumann(s), Numan, Nauman, Neiman, and Nyeman. Its first recorded uses were Godwin Nieweman in Oxfordshire, England, in 1169, and in Germany, Herman Nyeman of Barth in 1325. It was mostly likely originally used as a nickname for a recent arrival or settler.
