Eric Berne (May 10, 1910 – July 15, 1970) was a Canadian-born psychiatrist who created the theory of transactional analysis as a way of explaining human behavior. Berne's theory of transactional analysis was based on the ideas of Freud but was distinctly different. Freudian psychotherapists focused on talk therapy as a way of gaining insight to their patient's personalities. Berne believed that insight could be better discovered by analyzing patients’ social transactions. Background and education (1927–1938) Eric Berne was born on May 10, 1910, in Montreal, Quebec, Canada, as Eric Lennard Bernstein. He was the son of David Hillel Bernstein, MD, a general practitioner, and Sarah Gordon Bernstein, a professional writer and editor. His only sibling, his sister Grace, was born five years later. The family immigrated to Canada from Poland and Russia. Both parents graduated from McGill University in Montreal. Eric was close to his father and spoke fondly of how he accompanied his father on rounds, traveling by horse-pulled sleigh on cold Montreal winters to visit patients. Berne's father died of tuberculosis when Berne was 11. His mother then supported herself and her two children working as an editor and writer. She encouraged her son to follow in his father's footsteps and to study medicine. Berne received his baccalaureate degree in 1931 and an M.D. and C.M. (Master of Surgery) from McGill University Medical School in 1935. Berne came to the United States in 1935 when he began an internship at Englewood Hospital in New Jersey. After completing his one-year internship in 1936, he began his psychiatric residency at the Psychiatric Clinic of Yale University School of Medicine, where he worked for two years. In 1939, Berne became an American citizen and shortened his name from Eric Lennard Bernstein to Eric Berne. In 1949, he was admitted as a Fellow in the American Psychiatric Association. Career (1938–1970) From 1938 to 1940, Berne was an assistant physician at Ring Sanitarium, Arlington Heights, Massachusetts. From 1940 to 1943 he was employed as a psychiatrist in a sanitarium in Connecticut, and concurrently as a clinical assistant in psychiatry at Mt Sinai Hospital in New York. He also maintained a private practice. In 1943, during World War II, Berne joined the United States Army Medical Corps and served as a psychiatrist. He rose from the rank of Lieutenant, to Captain, and then to Major. His assignments included Spokane, Washington, Ft. Ord, California
