John E. Flaherty is professor emeritus of management at Pace University in New York City, where he was formerly dean of the Graduate School of Business and chairman of the Social Science Department. He first encountered Peter Drucker while auditing one of Drucker's management courses at New York University in the mid 1950s. Over the years, Flaherty has followed and kept notes on the material from Drucker's lectures, books, articles, conversations, and correspondence-many of which have found their way into Peter Drucker: Shaping the Managerial Mind.
