My name is Klaus Fuchs. I was born on December 29, 1911.
At the outbreak of war I was a German citizen, interned in a camp in Quebec, Canada. However, Max Born a professor of Edinburgh University intervened on my behalf, and by early 1941, I returned to Edinburgh.
When returned to Edinburgh, I was approached by Rudolf Peierls to work on the British atomic bomb research project. I became a British citizen in 1942.
There I started spying for the Soviet Union and through Ruth Kuczynski, I passed on significant project information. i also started working on the Manhattan Project at the Columbia University in New York.
In Los Alamos National Laboratory I worked at the Theoretical Physics Division. I was involved in several important theoretical calculations associated with first nuclear weapons and hydrogen bomb.
Klaus Fuchs died in east Berlin on January 28, 1988 at the age of 76.
