Chester Barnard grew up poor and worked various jobs to pay for his education at Harvard University, where he studied economics. Although he nearly completed his degree, he was unable to finish due to lack of funds. Barnard is best known for his influential 1938 book "The Functions of the Executive", which was based on his decades of experience as a senior executive. In the book, he presents organizations as cooperative systems and explores concepts like the elements that comprise an organization, authority, motivation, and the functions of an executive in maintaining the organization and defining its objectives. The book had a significant impact and remains influential in the study of management and organizations.
