A genogram (also known as a McGoldrick–Gerson study, a Lapidus schematic or a family diagram) is a pictorial display of a person’s family relationships and medical history. It goes beyond a traditional family tree by allowing the user to visualize hereditary patterns and psychological factors that punctuate relationships. It can be used to identify repetitive patterns of behavior and to recognize hereditary tendencies.Murray Bowen invented the concept of the genogram as part of his family systems model in the 1970s. Genograms were later developed and popularized in clinical settings by Monica McGoldrick and Randy Gerson through the publication of a book titled Genograms: Assessment and Intervention in 1985. Genograms are now used by various groups of people in a variety of fields such as medicine, psychiatry, psychology, social work, genetic research, education, and many more. Some practitioners in personal and family therapy use genograms for personal records and/or to explain family dynamics to the client. Few if any genealogists use them.
