In the early 20th century, people like Ordway Tead (1891–1973), Walter Scott and J. Mooney applied the principles of psychology to management, while other writers, such as Elton Mayo (1880–1949), Mary Parker Follett (1868–1933), Chester Barnard (1886–1961), Max Weber (1864–1920), Rensis Likert (1903–1981), and Chris Argyris (* 1923) approached the phenomenon of management from a sociological perspective.
