First established as the Peter F. Drucker Foundation for Nonprofit Managment, the Leader to Leader Institute's mission is to strengthen the leadership of the social sector. In collaboration with its partners in the private and public sectors, the Institute furthers its mission by providing social sector leaders with the essential leadership wisdom from all sectors and the resources needed to lead for innovation and to build vibrant organizations. 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.
