Daniel Harold Casriel, M.D., born in New York City on March 1, 1924, was an American psychiatrist, psychoanalyst and writer. He was a past president of the American Society of Psychoanalytic Physicians. He founded the Daytop treatment centers.
Casriel died on June 7, 1983 at the age of 59 from a form of Amyotrophic Lateral Sclerosis (ALS).
After graduation from the University of Cincinnati College of Medicine at age twenty-five, Casriel began his residency at the Kingsbridge Veterans' Administration Hospital. Less than a year into his residency, he was drafted and sent to Okinawa where he served as an Army psychiatrist.
Beyond shaping the field of addictions treatment and psychotherapy, Casriel profoundly influenced the launch of relationship education. His intensive couples workshops for Lori Heyman Gordon's Family Relations Institute in Northern Virginia provided the framework for what emerged into the range of PAIRS' relationship education seminars and trainings that have touched millions of lives.
Casriel popularized the theory that the "emotion of love" comes from the anticipation of pleasure.
Based on Casriel's theory, "bonding," which he defined as "the unique combination of emotional openness and physical closeness with another human being," is central to sustaining healthy, intimate relationships. Casriel taught that symptoms of bonding deprivation include: "illness, fatigue, depression, rigidity, constriction, isolation, and the range of anti-social behaviors such as drug and alcohol abuse, gambling and sex addictions." Casriel considered bonding a biologically-based need similar to the need for food, water, air, and shelter, yet unique as the only biological need people cannot meet for themselves.
