Henri Fayol was a French mining engineer and director who developed one of the earliest comprehensive theories of management. After graduating from the National School of Mines in 1860, he spent his entire career at a mining company in France, eventually becoming managing director. He is credited with saving the company from bankruptcy. In his retirement, he established the Center of Administrative Studies and developed 14 principles of management, including division of work, authority, discipline, unity of command, and subordination of individual interests. He argued that the same skills are needed to manage different organizations and established management as a distinct field of study.
