Sigmund Freud and Heinrich Braun (the subject of the letter) were close friends during Freud's adolescence. After Braun's death many years later his widow wrote asking what Freud remembered about his former friend. Freud's reply not only reveals some details of his adolescence but also casts very interesting light on Freud's motives in acquiring the house at Berggasse 19 in which he lived for so many years.
