Robert K. Greenleaf, the former director of management research at AT&T and an iconoclastic thinker about how organizations should work. After retiring from AT&T in 1964, Greenleaf had started the Center for Applied Ethics (later renamed the Robert K. Greenleaf Center) and embarked on a second career as a university lecturer, consultant, and author. Along the way, he had written a series of seminal essays on the theme of “servant leadership,” and they continued to resonate long after his death in 1990.
