American management consultant, social worker and philosopher
Mary Parker Follett (3 September 1868 – 18 December 1933) was an American management consultant, social worker, philosopher and pioneer in the fields of organizational theory and organizational behavior. Along with Lillian Gilbreth, she was one of two great women management experts in the early days of classical management theory. She has been called the "Mother of Modern Management". Instead of emphasizing industrial and mechanical components, she advocated for what she saw as the far more important human element, regarding people as the most valuable commodity present within any business.
