event, she never returned to western Europe, and the papers remained undiscovered until they were identified nearly sixty years later by the Jungian analyst Aldo Carotenuto, who published a selection of them. The archive remains in the possession of the heirs of Édouard Claparède, and although further selections have been published in a number of books and journals, it has never been fully examined or catalogued. Russian career 1923–1942 Psychoanalysis in Russia already had a turbulent history but its influence was strongest between 1921 and 1923. On her arrival in Moscow, she found herself the most experienced psychoanalyst there, as well as one of the most closely connected with analysts and psychologists in the west. She was appointed to a chair in child psychology at First Moscow University, and took up work in pedology (children study), an approach to pediatrics that integrated it with developmental and educational psychology. She also joined the Moscow Psychoanalytic Institute, which had been founded in 1922 under the direction of Moise (Moishe) Wulff. She then became involved with an ambitious new project in children's learning known as the "Detski Dom" Psychoanalytic Orphanage–Laboratory (also known as the "White House.") Founded in 1921 by Vera Schmidt (who had also been one of Freud's students), the "Detski Dom" was intended to teach children based on Freud's theories. The school was only an orphanage in name: along with Schmidt's own son, the school had children from prominent Bolsheviks (including Joseph Stalin, whose son Vasily Stalin was enrolled as well). Use of discipline was avoided and children were allowed maximum freedom of movement. Sexual exploration and curiosity was also permitted. Spielrein's involvement included supervision of the teachers, and she may have supported them in a protest about their poor conditions of work, which led to their dismissal. The school had to close in 1924, in the wake of accusations of experiments to stimulate the children's sexuality prematurely. The accusations were possibly made in response to attempts by Leon Trotsky to proletarianize the school's intake During Spielrein's time in Moscow, both Alexander Luria and Lev Vygotsky came to work at the Psychoanalytic Institute and "Dyetski Dom" and studied with her. Spielrein's characteristic way of combining subjective psychological ideas from psychoanalysis with objective observational research of children is likely to have been an important influence in their early formation as researchers, leading them to become the foremost Russian psychologists of their time.
