fessor now living in the Soviet
occupation zone Of Germany.
The younger Fuchs originally
went to England in 1888 as a
student and remained there as an
instructor in physics. He first
came to this country in November,
1943, on an atomic mission for
the British government and re-
manned in the United States until
June. 1916.
After landing at Newport News,
Va, he spent some time with the
British Ministry of Supply Office
in New York City. Later he was
assigned to Washington, to the
atom plant at Oak Ridge, Tenn,
and to the Los Alamos laboratories
which produced the first A-bomb.
Fuchs made trips to both Mex
leo and Canada before returning
to England.
He came here again in Novem-
ber, 1947, to attend atomic Sc
curity conferences with American
officials, and shortly afterward
went back to London.
The FBI turned over it's findings
on Fuchs to the British intelli-
gence service. which carried on
the investigation in England.
Second Development in Week.
Fuchs arrest is the second
major atomic development of the
week. Only last Tuesday Presi-
dent Truman gave a formal 60
ahead for the production of
hydrogen super bomb. 1t could be
up to 1000 times more powerful
than the uranium bombs now be-
ing assembled on an assembly
line basis.
Britain has not had access to
any A-bomb secrets since 1916.
That is because the Atomic
Energy Act passed that year
strictly forbids sharing the Sc
crets with any foreign nation.
However, both British and Cana
dian scientists worked closely with
the Americans in the wartime de-
velopment of the atomic bomb.
They were present as observers
when the worlds first A-bomb was
exploded in a New Mexico desert
in July, 1945.
They, along with the Russians
and many other foreigners, were
on hand for the Bikini tests of
1946. But from that point on,
the United States has worked
alone on military phases of
atomic energy.
Member of British Mission.
The Acc statement concerning
Fuchs said he was engaged in
project work on the A-bomb de-
velopment from December, 1943.
to June, 1916, as a member of
British atomic mission to the
United States.
The Acc said he first was en-
gagged in early work on the "gase-
GUS diffusion process" in New York
City. The gaseous diffusion
process is one of three processes
eventually worked out for the sep
aration of uranium-235, used in
the bomb. from uranium as it
occurs in nature.
The gaseous diffusion process Is
believed to be the most efficient
of the three.
The Acc said Fuchs "had ac-
cess to wide area of the most
vital weapons information" after
he went to Los Alamos with the
British scientific team assigned to
weapons work. sd
The statement said Fuchs has
not been employed in the Amer
lean atomic energy project since
he returned to England in June,
1916. Iaf
The Acc said Fuchs did, how
ever, visit the United States in
November, 1947. as a member of
the British delegation to take part
in talks on the use of the de-
classification guide. This guide,
developed in 1856 has been used
by Canada and the United King
dom since April. 1916.
The Acc said the late 1947 con-
ference was limited to fields of
information shared by the three
countries as. result of their COM
bined wartime efforts in the de-
velopment of atomic energy"
The Acc said that in 1947
Fuchs also was permitted to visit
the Argonne National Laboratory
in Chicago "for discussions lin
tied to non-secret scientific ma
terials."
