The Communist Party said that I must finish my studies because after the revolution in Germany people would be required with technical knowledge to take part in the building of the Communist Germany.

Before I joined the project most of the English people with whom I had made personal contacts were left wing and affected to some degree or other by the same kind of philosophy.

In the post war period I began again to have my doubts about Russian policy.

I was a student in Germany when Hitler came to power.

I was in the underground until I left Germany.

Since coming to Harwell I have met English people of all kinds, and I have come to see in many of them a deep rooted firmness which enables them to lead a decent way of life.

I was lucky because on the morning after the burning of the Reichstag I left my home very early to catch a train to Berlin for the conference of our student organization and that is the only reason why I escaped arrest.
