David Clarence McClelland (May 20, 1917, Mount Vernon, New York - March 27, 1998, Lexington, Massachusetts) was a behavioral psychologist.
He proposed a content theory of motivation based on personality and learned needs. Most of his work was however focused in secondary need(learned need). His theory of manifest needs claims that human motivation are a result of three manifest needs. These are the need for achievement (N-Ach), the need for power (N-Pow) and the need for affiliation (N-Affil). The importance of each need varies from individual and cultural background. For example, some individuals value achievement more than affiliation. McClelland's theory is closely related to the work of Frederick Herzberg.
