By the 1920s, scholars of public administration had responded to Wilson's solicitation and thus textbooks in this field were introduced.
A few distinguished scholars of that period were, Luther Gulick, Lyndall Urwick, Henri Fayol, Frederick Taylor, and others.
Frederick Taylor (1856-1915), another prominent scholar in the field of administration and management also published a book entitled ‘The Principles of Scientific Management’ (1911).
