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.

At this time I had complete confidence in Russian policy and believed that the Western Allies deliberately allowed Germany and Russia to fight each other to death.

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.

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

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

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.

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.

Shortly afterwards my father told me that he might be going into the Eastern Zone of Germany. At that time my own mind was closer to his than it had ever been before, because he also believed that they are at least trying to build a new world.

At that time I had complete confidence in Russian policy and I believed that the Western Allies deliberately allowed Russia and Germany to fight each other to the death.

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

The last time when I handed over information was in February or March 1949.

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.

I had therefore, no hesitation in giving all the information I had, even though occasionally I tried to concentrate mainly on giving information about the results of my own work.

Finally Germany’s attack on Russia seemed to confirm that Russia was not shirking and was prepared to carry out a foreign policy with the risk of war with Germany.

Since that time I have had continuous contact with the persons who were completely unknown to me, except that I knew they would hand whatever information I gave them to the Russian authorities.

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 think the one thing that most stands out is that my father always did what he believed to be the right thing to do and he always told us that we had to go our own way even if he disagreed.

There is nobody I know by name who is concerned with collecting information for the Russian authorities. There are people whom I know by sight whom I trusted with my life.
