Alfred Binet and the laboratory of psychology at the Sorbonne

This paper is intended to present the history of the laboratory of psychology at the Sorbonne established by the physiologist Henry Beaunis (1830-1921) and to estimate the contribution of Alfred Binet (1857-1911) at the brilliance of this structure of research. The reconstruction of this history thanks to little known or unpublished documents brought to us to think about the inheritance left by Binet whose laboratory was entrusted after his death to Henri Pieron (1881-1964) then to Paul Fraisse (1911-1996). The article ends by asking the question of the inheritance of the laboratory of psychology at the Sorbonne directed by Binet.
