Biography

Carl Gustav Jung was born in Kesswil, Switzerland, on July 26, 1875. He studied medicine at the University of Basel, worked at the Burghölzli psychiatric hospital in Zürich under Eugen Bleuler, and later built a private practice. He collaborated with Sigmund Freud from about 1907 until their break around 1913.

In 1921 he published Psychological Types, distinguishing introversion from extraversion and describing thinking, feeling, sensation, and intuition as psychological functions that can operate in introverted or extraverted attitudes. He did not create a sixteen-type questionnaire or the label INFJ.

Jung died in Küsnacht, Switzerland, on June 6, 1961. Katharine Cook Briggs and Isabel Briggs Myers later adapted his typology into American questionnaire practice—they were not his personal students.

Reputation

Jung’s typology in Psychological Types is historically central to MBTI and INFJ discourse, but it is not the same system as modern four-letter profiles: Jung emphasized dominant function and compensation, not sixteen fixed types.
