Klaus Fuchs quotes:

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.

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.

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 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.

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

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

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.

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 a student in Germany when Hitler came to power.

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.

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.

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.
