Chester Barnard (1886-1961)

He studied economics at Harvard but could not complete it. He jointed die Bell telephone and became an executive. His contributions to management science were in the areas of organization, motivation, authority, communication, etc.

In short, his contributions were appreciated by George as, ‘he had a more profound impact on the thinking about the complex subjects matter of human organization than any other contributor to the continuum of management thought. He has brought more scholarly and scientific insight into the totality of managerial organizations than any prior individual’.
