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

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

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.

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

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.

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