PEIERLS, SIR RUDOLF.Born in Berlin and naturalized a British cit-
izen in February 1940, Rudolf Peierls was one of the leading atomic
physicists of the era. He was well acquainted with Klaus Fuchs, who
he said ‘‘had been politically active as a member of a socialist student
group [which was essentially communist].’’ Peierls had brought
Fuchs into the British research team working on the atomic bomb
and had arranged his security clearance in May 1941. Fuchs went to
live with the Peierls as a lodger in Birmingham, traveled to America
with him on theAndesin November 1943, and even went on a motor-
ing holiday with him to Mexico in December 1945 when the British
contingent completed its work at Los Alamos.
Peierls attracted much attention fromMI5and theFederal Bu-
reau of Investigation(FBI), not least because he was married to a
Russian physicist, Eugenia Kannegiesser, whom he met while on a
visit to Odessa in the summer of 1930. They were married in Lenin-
grad in March 1931, and to their surprise no obstacles were placed
on her emigration abroad nor on her acquisition of German citizen-
ship. This was unusual, considering the sensitive nature of her work
and her family circumstances: her sister Nina was a biologist and her
widowed mother had married a writer. Coincidentally, Peierls’s older
brother Alfred had also married a Russian, a woman who had been
working for the Soviet Trade Delegation in Berlin when they met in
a minor road accident. Alfred was an expert on electric condensers
and, after he fled Germany in 1935, managed a condenser factory in
London until his internment on the Isle of Man, with his wife, as an
enemy alien.
