Erik Homburger Erikson (born Erik Salomonsen; 15 June 1902 – 12 May 1994) was a German-American child psychoanalyst and visual artist known for his theory on psychosocial development of human beings. He coined the phrase identity crisis.

Despite lacking a university degree, Erikson served as a professor at prominent institutions, including Harvard, University of California, Berkeley, and Yale. A Review of General Psychology survey, published in 2002, ranked Erikson as the 12th most eminent psychologist of the 20th century.

Early life, family and education Erikson's mother, Karla Abrahamsen, came from a prominent Jewish family in Copenhagen, Denmark. She was married to Jewish stockbroker Valdemar Isidor Salomonsen but had been estranged from him for several months at the time Erik was conceived. Little is known about Erik's biological father except that he was a non-Jewish Dane. On discovering her pregnancy, Karla fled to Frankfurt am Main in Germany where Erik was born on 15 June 1902 and was given the surname Salomonsen. She fled due to conceiving Erik out of wedlock, and the identity of Erik's birth father was never made clear.

Following Erik's birth, Karla trained to be a nurse and moved to Karlsruhe, Germany. In 1905, she married Theodor Homburger, a Jewish pediatrician. In 1908, Erik surname was changed from Salomonsen to Homburger, and in 1911 he was officially adopted by his stepfather. Karla and Theodor told Erik that Theodor was his real father, only revealing the truth to him in late childhood; he remained bitter about the deception and betrayal all his life.

The development of identity seems to have been one of Erikson's greatest concerns in his own life as well as being central to his theoretical work. As an older adult, he wrote about his adolescent "identity confusion" in his European days. "My identity confusion", he wrote, "[was at times on] the borderline between neurosis and adolescent psychosis." Erikson's daughter wrote that her father's "real psychoanalytic identity" was not established until he "replaced his stepfather's surname [Homburger] with a name of his invention [Erikson]." The decision to change his last name came about as he started his job at Yale, and the "Erikson" name was accepted by Erik's family when they became American citizens. It is said his children enjoyed the fact they would not be called "Hamburger" any longer.

Erik was a tall, blond, blue-eyed boy who was raised in the Jewish religion. Due to these mixed identities, he was a target of bigotry by both Jewish and gentile children. At temple school, his peers teased him for being Nordic; while at grammar school, he was teased for being Jewish. At Das Humanistische Gymnasium, his main interests were art, history and languages, but he lacked a general interest in school and graduated without academic distinction. After graduation, instead of attending medical school as his stepfather had desired, he attended art school in Munich, much to the liking of his mother and her friends.

Uncertain about his vocation and his fit in society, Erik dropped out of school and began a lengthy period of roaming about Germany and Italy as a wandering artist with his childhood friend Peter Blos and others. For children from prominent German families, taking a "wandering year" was not uncommon. During his travels, he often sold or traded his sketches to people he met.

Early career, psychoanalytic experience and training Eventually, Erik realized he would never become a full-time artist and returned to Karlsruhe and became an art teacher. During the time he worked at his teaching job, Erik was hired by an heiress to sketch and eventually tutor her children. Erik worked very well with these children and was eventually hired by many other families that were close to Anna and Sigmund Freud. This teaching extended into a small experimental school based in the house of Eva Rosenfeld. During this period, which lasted until he was twenty-five years old, he continued to contend with questions about his father and competing ideas of ethnic, religious, and national identity.

When Erikson was 25 years old, his friend Peter Blos invited him to Vienna to tutor art at the small Burlingham-Rosenfeld School for children whose affluent parents were undergoing psychoanalysis by Sigmund Freud's daughter, Anna Freud. Anna noticed Erikson's sensitivity to children at the school and encouraged him to study psychoanalysis at the Vienna Psychoanalytic Institute, where prominent analysts August Aichhorn, Heinz Hartmann, and Paul Federn were among those who supervised his theoretical studies. He specialized in child analysis and underwent a training analysis with Anna Freud. Helene Deutsch and Edward Bibring supervised his initial treatment of an adult. Simultaneously, he studied the Montessori method of education, which focused on child development and sexual stages. In 1933, he received his diploma from the Vienna Psychoanalytic Institute. This and his Montessori diploma were to be Erikson's only earned credentials for his life's work.

United States In 1930, Erikson married Joan Mowat Serson, a Canadian dancer and artist whom Erikson had met at a dress ball. During their marriage, Erikson converted to Christianity. In 1933, with Adolf Hitler's rise to power in Germany, the burning of Freud's books in Berlin, and the potential Nazi persecution and threat to Austria, the family left an impoverished Vienna with their two young sons and emigrated to Copenhagen. Unable to regain Danish citizenship because of residence requirements, the family left for the US, where citizenship would not be an issue.

In the United States, Erikson became the first child psychoanalyst in Boston and held positions at Massachusetts General Hospital, the Judge Baker Guidance Center, and at Harvard Medical School and Psychological Clinic. This was while he was establishing a singular reputation as a clinician. In 1936, Erikson left Harvard and joined the staff at Yale University, where he worked at the Institute of Social Relations and taught at the medical school.

Erikson continued to deepen his interest in areas beyond psychoanalysis and to explore connections between psychology and anthropology. He made important contacts with anthropologists such as Margaret Mead, Gregory Bateson, and Ruth Benedict. Erikson said his theory of the development of thought was derived from his social and cultural studies. In 1938, he left Yale to study the Sioux tribe on their reservation in South Dakota. After his studies in South Dakota, he traveled to California to study the Yurok tribe. Erikson discovered differences between the children of the Sioux and Yurok tribes. This marked the beginning of Erikson's lifelong passion of showing the importance of events in childhood and how society affects them.

In 1939, he left Yale, and the Eriksons moved to California, where Erik had been invited to join a team conducting a longitudinal study of child development at the University of California at Berkeley's Institute of Child Welfare. In addition, in San Francisco, he opened a private practice in child psychoanalysis.

While in California he was able to make his second study of Native American children when he joined anthropologist Alfred Kroeber on a field trip to Northern California to study the Yurok people.

In 1950, after publishing the book, Childhood and Society, for which he is best known, Erikson left the University of California when California's Levering Act required professors there to sign loyalty oaths. From 1951 to 1960, he worked and taught at the Austen Riggs Center, a prominent psychiatric treatment facility in Stockbridge, Massachusetts, where he worked with emotionally troubled young people. Another famous Stockbridge resident, Norman Rockwell, became Erikson's patient and friend. During this time, he also served as a visiting professor at the University of Pittsburgh where he worked with Benjamin Spock and Fred Rogers at Arsenal Nursery School of the Western Psychiatric Institute.

He returned to Harvard in the 1960s as a professor of human development and remained there until his retirement in 1970. In 1973, the National Endowment for the Humanities selected Erikson for the Jefferson Lecture, the United States' highest honor for achievement in the humanities. Erikson's lecture was titled Dimensions of a New Identity.

Theories of development and the ego

Erikson is credited with being one of the originators of ego psychology, which emphasized the role of the ego as being more than a servant of the id. Although Erikson accepted Freud's theory, he did not focus on the parent-child relationship and gave more importance to the role of the ego, particularly the person's progression as self. According to Erikson, the environment in which a child lived was crucial to providing growth, adjustment, a source of self-awareness and identity. Erikson won a Pulitzer Prize and a US National Book Award in category Philosophy and Religion for Gandhi's Truth (1969), which focused more on his theory as applied to later phases in the life cycle.

In Erikson's discussion of development, he rarely mentioned a stage of development by age. In fact he referred to it as a prolonged adolescence which has led to further investigation into a period of development between adolescence and young adulthood called emerging adulthood. Erikson's theory of development includes various psychosocial crises where each conflict builds off of the previous stages. The result of each conflict can have negative or positive impacts on a person's development, however, a negative outcome can be revisited and readdressed throughout the life span. On the topic of ego identity versus role confusion: ego identity enables each person to have a sense of individuality, or as Erikson would say, "Ego identity, then, in its subjective aspect, is the awareness of the fact that there is a self-sameness and continuity to the ego's synthesizing methods and a continuity of one's meaning for others". Cited in . Role confusion, however, is, according to Barbara Engler, "the inability to conceive of oneself as a productive member of one's own society." This inability to conceive of oneself as a productive member is a great danger; it can occur during adolescence, when looking for an occupation.

Theory of personality

The Erikson life-stages, in order of the eight stages in which they may be acquired, are listed below, as well as the "virtues" that Erikson has attached to these stages, (these virtues are underlined). The term "virtue" refers to favorable outcomes of each stage and is used in the context of Erikson's work as it is applied to medicine, meaning "potencies". These virtues are also interpreted to be the same as "strengths", which are considered inherent in the individual life cycle and in the sequence of generations. Erikson's research suggests that each individual must learn how to hold both extremes of each specific life-stage challenge in tension with one another, not rejecting one end of the tension or the other. Only when both extremes in a life-stage challenge are understood and accepted as both required and useful, can the optimal virtue for that stage surface. Thus, 'trust' and 'mis-trust' must both be understood and accepted, in order for realistic 'hope' to emerge as a viable solution at the first stage. Similarly, 'integrity' and 'despair' must both be understood and embraced, in order for actionable 'wisdom' to emerge as a viable solution at the last stage.
