Dwight m
English: transferred use of the surname, which probably comes from the medieval English female name Diot, a pet form of Dionysia (see DENNIS (SEE Dennis)). It is especially common in America, where its increase in popularity since the Second World War is mainly a result of the fame of the American general and president Dwight D. Eisenhower (1890–1969). He was apparently named in honour of the New England thinker Timothy Dwight (1752–1817) and his brother Theodore Dwight (1764–1846).
