Dr. Laurence Johnston Peter (September 16, 1919 - January 12, 1990) was an educator and "hierarchiologist", best known to the general public for the formulation of the Peter Principle.

He was born in Vancouver, British Columbia, and began his career as a teacher in 1941. He received the degree of Doctor of Education from Washington State University in 1963.

In 1964, Peter moved to California, where he became an Associate Professor of Education, Director of the Evelyn Frieden Centre for Prescriptive Teaching, and Coordinator of Programs for Emotionally Disturbed Children at the University of Southern California.

He became widely famous in 1968, on the publication of The Peter Principle, in which he states: "In a hierarchy every employee tends to rise to his level of incompetence ... in time every post tends to be occupied by an employee who is incompetent to carry out its duties ... Work is accomplished by those employees who have not yet reached their level of incompetence." The Peter Principle became one of the most profound principles of management from the University of Southern California. It is a heavily quoted principle at the Marshall School of Business.
