Erving Goffman introduced the idea of dramaturgical analysis in his 1959 book "The Presentation of Self in Everyday Life". He argued that everyday social interactions are like theatrical performances, with individuals presenting different versions of themselves depending on the audience. Specifically, people project a "front stage self" to unfamiliar others and a more genuine "back stage self" among close acquaintances. Goffman also discussed how people use "impression management techniques" to control how they are perceived by others.
