In this year conditions in Germany had become so difficult that Heinrich Peierls decided he must leave. His health was indifferent and he was temperamentally reluctant to make a final break; money and visa problems were compounded by the delay. Correspondence includes letters from Peierls to his father, to his American uncle and aunt (Siegfried and Jenny) and to UK authorities to try to make arrangements; there is also a larger proportion of correspondence from Else.
