Peter F. Drucker is known as the "father of modern management," and is a best-selling author of thirty-two books including the best-seller The Effective Executive. He is world-renowned thinker on leadership and management and his work has been featured in every major business periodical. A consultant to senior executives for more than fifty years Drucker passed away in 2005. Since Drucker's death, interest in him, his concepts and his books has only grown. His ideas continue to be as relevant today as they were when he first voiced them.

Jim Collins, Philip Kotler, Jim Kouzes, Judith Rodin and Kash Rangan are all well established thought leaders themselves, some with multiple best-sellers.
