John Mordecai Gottman (born April 26, 1942) is a professor emeritus in psychology known for his work on marital stability and relationship analysis through scientific direct observations, many of which were published in peer-reviewed literature. The lessons derived from this work represent a partial basis for the relationship counseling movement that aims to improve relationship functioning and the avoidance of those behaviors shown by Gottman and other researchers to harm human relationships. His work has also had a major impact on the development of important concepts on social sequence analysis. Gottman is a professor emeritus of psychology at the University of Washington. With his wife, Julie Schwartz, Gottman heads a non-profit research institute (The Relationship Research Institute) and a for-profit therapist training entity (The Gottman Institute).
