That’s where he met Laura Possner, a student who ended up becoming his wife two years later. He decided he wanted to become an analyst. But he had to move to Frankfurt to take a position as an assistant to a psychiatrist named Kurt Goldstein, who was working on the theory of Gestalt psychology. This bad period lead him to start psychoanalysis with Karen Horney. But he came back frustrated after they wouldn’t validate his license because he didn’t speak English. Later on he specialized in Neuropsychiatry. Then he met the philsopher Friedlander, whose influence was crucial to Perls’ work. In 1920 Fritz Perls received his license as a doctor from the Frederick Wilhelm University of Berlin.
