Dr. Stuart Brown is a medical professional trained in general and internal medicine, psychiatry, and clinical research. His studies on the importance of play began with research on homicidal young males and felony drunk drivers, where he found a common lack of play during childhood. Throughout his career, he held various positions at prestigious institutions, including Baylor College of Medicine, Harvard's McLean Hospital, Mercy Hospital and Medical Center, and UCSD School of Medicine.

Dr. Brown documented thousands of personal play profiles, demonstrating the negative consequences of a play-deprived life and the presence of ongoing play in successful individuals. In 1989, he left clinical medicine to study animal play, collaborating with the National Geographic Society and Jane Goodall. This research led him to understand the importance of play for human well-being and survival.

Dr. Brown founded the National Institute for Play to promote play's integral role in human development. He has written, lectured, and produced documentaries on the topic, and authored the book Play: How It Shapes the Brain, Opens the Imagination, and Invigorates the Soul.
