Clayton M. Christensen is one of the best-known and most influential thinkers on innovation theory and practice. His research led to one of the most important ideas of the twentieth century--disruptive innovation. As a professor at Harvard Business School, he influenced generations of leaders and entrepreneurs. He authored twelve books, including five New York Times bestsellers, and over one hundred articles on disruptive innovation in business, healthcare, and education. The Economist named The Innovator's Dilemma one of the six most important books about business ever written. Christensen is a winner of the Global Business Book Award; was twice named the World's Greatest Business Thinker; won the Abernathy, Newcomen, James Madison, and Circle prizes; and was a five-time recipient of the McKinsey Award, given each year to the best articles published in Harvard Business Review. Christensen cofounded Innosight, a management consultancy; Rose Park Advisors, an investment firm; and the Clayton Christensen Institute, a nonprofit think tank. He was a friend and mentor to some of the most important innovators of our time. He and his wife are the proud parents of five children, and they have eleven grandchildren.
