Peter Drucker

Elizabeth Haas Edersheim on the original management Jedi Master:

1. Drucker's work is widely accepted as foundational in creating a theory of management as the foundation of a functioning society, despite not being widely taught in business schools. Leading scholars consistently see him as a source of insight and inspiration, many of whom credit Peter Drucker not only as the creator of the discipline of management but as the basis for their own work. Stephen Covey, author of The 7 Habits of Highly Effective People, said, "I can find everything I've written in Peter's work, 25 years before I thought of it." Professor Hideyuki Inoue of Keio University said, "Everything we know about knowledge worker productivity is built on the foundation Peter Drucker wrote about 50 years ago." Phillip Kotler, Distinguished Professor of International Marketing at the Kellogg School said, "If I am the father of marketing, Peter Drucker is the grandfather."

It strikes me as significant that Drucker is viewed as "foundational" by leading scholars but is not taught in B-school.
