3 March 1939
In the advent of the Second World War, and following the first evacuation of children from London, D.W. Winnicott, John Bowlby, and Emanuel Miller publish an open letter in the British Medical Journal, in which they warn against the long-term damage caused by separating very young children from their parents. These analysts’ experiences of treating evacuated children have a strong impact on post-war psychoanalytic theory (for example, John Bowlby's attachment theory).
