Karl A. Pillemer, Ph.D is a professor of human development at Cornell University and professor of gerontology in medicine at the Weill Cornell Medical College. An internationally renowned gerontologist, his research examines how people develop and change throughout their lives. He has authored five books and over 100 scientific publications, and speaks throughout the world on aging-related issues. In a groundbreaking research project, Dr. Pillemer decided to find out what older people know about life that the rest of us don't. This project led to the book: 30 Lessons for Living: Tried and True Advice from the Wisest Americans (Penguin/Hudson Street Press, 2011). He followed this up with surveys of hundreds of long-married elders on their advice for lifelong fulfilling relationships. His second book shares their wisdom: 30 Lessons for Loving: Advice from the Wisest Americans on Love, Relationships, and Marriage (Penguin/Hudson Street Press, 2015).
