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

I joined the Communist Party because I felt I had to be in some organization.

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.

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

I was ready to accept the philosophy that the Party is right and that in the coming struggle you could not permit yourself any doubts after the party had made a decision.

I was in the underground until I left Germany.
