On February 10, 1950, Fuchs was arraigned at the Bow Street Police
Court, London, and at that time a portion of his confession was read into
the record. This has not yet been obtained from the Official Record but
the portions appearing in the public press deal primarily with Fuchs
motivations in acting as an 8SpiO1'18-ge agent for the Soviet Government. A
copy of the information appearing in the press in the Evening Star of
February 10, 1950, is being attached. It might be noted that during the
arraignment the defense counsel at one point asked the f:overnma'1t prosecutor
as to whether or not Fuchs had been cooperative. The Government prosecutor
stated that Fuchs had been cooperative. This is believed to be some indication
that Fuchs may enter a plea of guilty when he is actually brought to trial.

been placed in the record and that nothing further need be introduced if Fuchs
enters a plea oi guilty at Old Bailey. They"anticipate that the case will not
appear on the calendar before I-{arch 6, '7, or 8, 1959. The British have flnther
reported that Fuchs is now eager to recall the details of his activitmes in
America. Another interview with Fuchs at his request is contemplated for Tuesda ,
February 14, 1950. The British have also now made available the New York address
of Fuchs which they state was 128 West 77th Street, telenhone number possibly!TR 4-6785. .u _ ' ~

which was made to the Security Office the Atomic Energy establi ent,
Harwell, England, and the third of which was made to the scientists inthe British
Ministry oi Supply. In addition, as mentioned previously, Fuchs has been
interviewed at his request since his arrest. It is felt that when the full results
of the interrogation of Fuchs are available there may be additional details
available to us, particularly in view oi his reported eagerness to cooperate
in regard to his espionage activities in the United States. We are furnishing
the British iithorities street maps of New York, Boston, and Santa Fe, in order
that the meetings oi Fuchs with his espionage contact may be more definitely

Background ' .»'
§Qmar§nna_Dprothe_lda Christel Fuchsheineman, commonly known as
Kristel Fuchs Heineman, the sister of Emil Julius-Klaus Fuchs, was born on
July 22, l9l3 possibly 191A!, at Huaaelsheim, Germany. According to 9
Immigration and Naturalization Service records, she resided in Germany frm
January, 1933, to September, 1933; in Switzerland, frm September, l933, to
July, l93L, where she is believed to have attended the University of Zurich;in Germany from July, 1934, to July, l936, and in England from July, 1936, //
to September, 1936. She first entered the United States as a student in ;
September, 1936, at New York City, thereafter attending Swarthmore College at 1/
Philadelphia, Pennsylvania, until her withdrawal during her fourth year ,
course in 1937-3s. On May 20, 1938. she re-entered the United States at '
ami, Florida, from Havana, Cuba, as a permanent resident, and on November 2,
1938, married Robert Block Heineman at Boston, Eassachusetts.- They now have
three children, Stephen Fox, age 10; Marcia Elizabeth, age 8; and Kristel,
age 6, all of whom were born in Cambridge, Massachusetts. Although she clahms to
have filed a petition for naturalization as a United States citizen at Boston, N
Massachusetts, in December of l9al, the files of the Immigration and
Naturalization Service at Boston have failed to reflect that her claim hasany basis.
Robert B. Heineman, whom Kristel Fuchs Heineman married on?November 2,
1938, was born at Wausau, Wisconsin, on March 25, 1917. According to a
highly confidential source of known reliability, he was registered as a member .
of the Cambridge Branc f the Communist Political Association in l9LL. Througha confidential source,1E§9nfidential Informant ND-B05 HS-100!, it was also
ascertained that on January 23, 19b7, he visited the Communist Party Headquarters
in Boston where he rejoined the Communist Party under the name of Robert Hill
64!It was also reported by the British Intelligence Service that on June 8, 193
Robert B.,Heineman arrived in ngland en route to Leni ad Russia, returning
to England in August of that same year via Italy and France. ring the school
year 1945-L6, Robert B. Heineman was employed as a teacher a he Antrim, New
Hampshire High School. It is reported that he did not return to that position
at the beginning of the next shool year, but within a short time thereafter,
went to Mexico, where he attended classes in Mexico City as a student. Robert
B. Heineman has admitted current active nenbership in the Communist Party and the
fact that Communist Party meetings have_recently been held at his home.
At the present time, Robert B. Heineman operates a launderette under _
the name of the Huron Self Service Store, 1&6 Huron Avenue, Cambridge, Massachusetts,
and is also enrolled in the Harvard University School of Education,
where he is studying for a degree as a Easter of Arts. His currentA1; that time he indicated that he had been a member oféhe Party until 193@§%L

Emil F uchs' internment inCanada but were unable to definitely indicate the
period during which he was held. - '

Also on February 2, 1950, Robert Block Heineman, the husband of
Kristel Fuchs Heineman, was interviewed. He admitted that in the past he had
been active in the Communist Party and stated that he knew Emil Julius Klaus
Fuchs. Heineman said that he knew that Emil Fuchs had visited with Kristel
Heineman but stated that he had been away from home on frequent occasions and A
did not know how often Fuchs had been there. He was not helpful in giving any

Robert Block Heineman was reinterviewed on February 3, 1950, at which
time he admitted former membership in the Young Communist League, but in spite
of evidence to the contrary, insisted that he had not been associated with
the Communist Party since 191.1. I-Ie provided no positive information concerning
Emil Julius Klaus Fuchs, claiming that he was absent from his own home on
almost every occasion that Fuchs had visited there. Heineman claimed that from

cooperative, and definitely appeared to be lying. - '
Robert Block Heineman was again interviewed on the evening of
February 1., 1950, at which time he became evasive and untruthful and indicated
his desire to consult an attorney. Thereupon he telephoned James F. Mahan,
a former Bureau agent engaged in the practice oi law, who counseled Heineman '
that he should be as cooperative as possible. Heineman then responded more
readily, admitting that he was currently an active member of the Communist
Party. He furnished his Party name and admitted that Commmist Party meetings
were held in his home. However, he refused to furnish the names of other
Comnunists, stating that he did not want to talk about people's political
beliefs, but was willing to give any informtion that might be of benefit in
connection with espionage activities. Qiestioned specifically concerning
contacts of Emil Fuchs while the latter was visiting the Heineman residence,
he furnished infomation concerning Theodore Ernst Velfort and a_n_indig_idualby the name of Deutsch since identified as Martin.-;Deutsch!. / He also stated",-that he knew that 'in"theSum:rer"1$I"I9li6,""Einii"'Puchs"an2IKFisftel Heinemsn had

1950, Kristel Fuchs Heinsman agreed with information supplied by obert B.
Heineman concerning this unidentified individual,_providing further information
which might be of assistance in effecting his identification. She agreed
generally with the description of the unknown men which had been furnished by
Robert Heineman, stating, however, that she was of the opinion that he was in
his forties. She said that she believed he had made some reference to a wife
and the fact that he had more than one child younger than her own second
child. Note: This would make the children of the unknown individual less than
four years of age in 1945!. According to Kristel Heineman'e recollection, '
the unknown individual had approached the Heineman residence by walking and it
was understood that he had come into the city by train. She also recalled
that when Emil Fuchs had heard that the man had been asking for him, he expressed
surprise over the fact that the unknown man had taken the trouble to come to the
house. It was Kristel Heineman's recollection that the unknown man had stayed -
for lunch on two occasions but that on the morning when he contacted Emil Fuchs,
he had stayed only a short time, perhaps about fifteen minutes. Kristel Heineman,
although appearing rational and cooperative during the interview, indicated that
she had no idea concerning the unknown in5ividual's name or the place from which
he had come. 1* Pa _m
Kristel Heineman has also advised that one Theodore Ernst Veltfort,
Jr., 8 close associate of Robert Heinemsn at Swarthmore College from 1936 to£938, and a member of the Loyalipt Brigade in Spain during 1937, had come to

_ W i '4 was mnrso snvrzs,.
On February 6, 1950, information was received from the Atomic Energy
Commission to the effect that at record had been located indicating that on
November 18, 1947, Fuchs had been authorized to visit the General Electric
Company, Schenectady, New York, b'_~.C3.plI-8111 W. A. Brook, U. S. Naval Inspector
oi Machines, at the General Electric Plant in Schenectady. At this time Fuchs
was shown a machine described as "'70-MEZD Synchroton.' According to the Atomic
Energy» Commission this record reflected that Fuchs inquired as to how this
machine worked and that the object of Fuchs visit was to see this machine.
At the time of this visit, according to the Atomic Energy Commission, the
General Electric Company in Schenectady was not doing work for the ABC although
it apparently was engaged in work for the Navy. I
Investigation has developed that the records of the Inspector of
U. S. Naval Material at General Electric Company, Schenectady, New York, reflect
that on November 1'7, 191.7, Fuchs, as a member of the British Atomic Energy
Research Establishment, visited Dr. Herbert C. Pollock, Research Laboratory,
General Electric Company, for the purpose oi discussing cyclotrons, synchrotrons
and betatrons. Pollock is described as a Research Associate in the Physics
Division oi General Electric assigned to the Synchrotron Project. _
These same records also reflect that on June 25, 1946, Fuchs,
as a member of the Iiazahattan District Project, paid a personal visit to
I Hans A. Bethe, Professor oi Physics of Cornell University and Acting,i Consultant for the General Electric Atomic Energy Froject. This conference
- took place in the office oi Dr. Kenneth H. Kingdon, General Manager ofl Schenectady Operation of the Nucleonics Department, General Electric Company.
*. Investigation to develop the identities oi persons contacted at General
Electric by Fuchs, his activities at the plant, and the nature of information
made available to Fuchs is continuing. _
Concerning the above-mentioned visit to Hans Ar. Bethe on June 25, 1946,
it will be recalled that Fuchs departed for the United Kingdom on June 28,1946. Ehe British have advised that on June 27, 1946, Fuchs wrote to a member
oi the British Mission, apparently in Washington, D. 0., from Cambridge,
on the stationery of the Windsor Hotel, Montreal, Canada. In this latter
letter Fuchs enclosed his traveling expenses for his flight from New York
to Boston to Montreal. He pointed out that he had spent five days in Cambridge
and Schenectady, partially on busi S9 and partially on social mattersbut predominantly the httezji Massachusetts, and that on June 28, 19/,6, he again wrote to this individual

On February 4, 1950; Dr. Samuel§¥'Goudsmit, physicist, Brookhaven
National Laboratory, Long Island, New York, advised that at a physics
meeting in Newark Dr. Karl Pa1ey__"mCohen_had advised him of a rather curious
episode between Cohen and Fuchs in 1947. According to Goudsmitis understanding
of the incident Cohen had receiveda phone call from Fuchs, who was then in
the United States for a declassication conference. Cohen invited Fuchs
to his home but Fuchs declinedand a luncheon date was made. During this
luncheon no business was discussed and this, according to Goudsmit, surprised
Cohen. Subsequent to the luncheon Fuchs called Cohen explaining that he had
borrowed a hat from a friend with nhomhe was staying and he asked Cohen to
obtain the hat at the restaurant and return it to the person from whom he had
borrowed it on Host lllth Street.
Dr. Cohen was interviewed on February 9, l950, at which time he
explained that he was Fuchs counterpart in the United States Atomic Energy
Program, that is, head of the Theoretical Physics Division. As such he had
been placed in frequent contact with Fuchs at the SA}.-i Laboratories, Columbia
University, up until the time that Cohen had left the Laboratory in May, 1944.
He said that of all the American scientists on the Atomic Energy Project
he probably knew Fuchs better and had more contact with him than any of the
others. He stated that his contact, however, was limited to business and
not to social contacts except for a farewell party which was given for Cohen
in May, 1941.. Cohen did not know where Fuchs had resided in New York but
he was aware that Fuchs had gone to Los Alamos after leaving New York. He
said that in January of 191.6, while he was employed by the Standard Oil
Development Company, he went to Los Alamos to obtain the services of a physicist
from the pool of Dos Alamos physicists which was then breaking up. He
recalled that at that time he had seen Fuchs and that Fuchs had loaned Cohen
his car to make a 500-mile trip into New Liexico and Colorado. Fuchs then
told him that he would be leaving for England in a short time. Cohen, however,
did not know the actual date when Fuchs left the United States.
Cohen continued, saying that he had no contact with Fuchs after
this until sometime in 191.? when a declassification conference was held in
Chicago. Cohen was told by Dr. Willard Libby of the Atomic Energy Commission
that he should discuss with Fuchs the declassification of a certain document
and make his recommendations for the conference. Cohen received a phone call
from a woman who explained that she was a friend 0: Fuchs, that Fuchs was staying
either at the Henry Hudson Hotel or Park Central Hotel, and that Fuchs wanted
to see Cohen. Thereafter Cohen called Fuchs and invited him to his home,
which invitation Fuchs declined. He and Fuchs, however, had dinner at a
restaurant of Cohen's choosing, during which time they discussed the de-
classification of the document, Cohen recommending that it be declassified
and Fuchs opposing. Cohen stated that sometime after leaving the restaurant

or the next day Fuchs realized he had left a hat in the restaurant which hat
belonged to the person with whom he had been staying. He asked Cohen to
pick it up and return it since he, Fuchs, was leaving town. Cohen said
that he told Fuchs that he regarded this request out of line but agreed to
call the people and tell them where they could obtain the hat. _Be did this
but the woman declined to retrieve the hat and consequently, a few days later,
Cohen obtained it and returned it. It was Cohen's recollection that Fuchs.
_contact was a pr. Cooper or Dr. Skinner, attached to the British Delegation
that was in the "United States for the Declassification Conference and who
was staying with his wife and her father on West lllth Street. He said that
when he returned the hat he met the scientistls wife and her father. He
described the wife as being typically Diglish but stated that her father was
of European extraction and spoke with an -accent. He said that on the bell
to the apartment house there wasthe name Cooper or Skinner as well as the
name of the father-in-law. He commented that he would have forgotten this
incident had- it not been for the recent publicity on Fuchs.
Dr. cohen accompanied Agents of the New York Office to West lllth
Street where he believes he located the apartment at 536 West lllth Street,
where the names on the bell are S1ci.n.ner, Hoffman and Hirsch.
Cohen stated that he had been astounded by the arrest of Fuchs,
when he regarded as a brilliant scientist but a person whoaaid very little
on any topic and never expressed himself on politics. He said that the
group of scientists at L03 Mamos, which included Bethe Hans A.!, Marsha}:
Robert!, and others, probably I-mew Fuchs better than he since they were
Living and working together with him. Cohen stated that he had maintained
a diary on officiallconferences held with Fuchs and others in 1943 and 1944.
Cohen appeared cooperative and willing to furnish in.tormati'on although he
did not volunteer anything nor appear curious as to the facts in the case.
Hhen he was asked whether he had corresponded with Fuchs after Fhchs left the
country in 191.6 he stated that the Agents should not have the "idea that
Fuchs would have wanted to recruit him since Fuchs knew more about the
atomic energy development than he , Cohen, did at any time.
Dr. Cohen made available his diary reflecting official conferences
in which Fuchs had participated. All of the information in the diary
reflecting meetings attended by Fuchs has been obtained. Cohen pointed
out that the diary, however, was not complete and that he had not kept it
after May of 1944. He also stated that his wife had reminded him that Fuchs
had visited at their home socially in the summer of 1943 and that Cohen had
"dominated the discussion." Cohen does not recall the subject matter of
discussion at that time but believed that it must have been gaseous
diffusion. It will be noted that Fuchs was not in the United States during
the summer of 1943 and that in all probability this incident occurred in the
summer of 1944.

has rented out this apartment to various roomers for the past six years.A
In view of the foregoing it would appear that Mrs. Skinner is the

INFORMATION AVAILABLE CONCERNING ABRAHAM BRDTHHAN1
r
' When Elizabeth T. Bentley was interviewed in the Fall of 1945, she
reported that in about May, 194.0, Jacob Golos, her Soviet espionage superior,
bad introduced her to Abraham Brothman who, at that time, was employed as an
engineer by the Republic Steel company in Rewyork. Brothman in subseqient
meetings had furnished her blusprintewhich on occasions had to be photostated.
In the Fall of 191.0, Golos told Bentley that Jae was discouraged with his dealings - -
with Brothnan and told her he was going to turn Bnothman over to someone else.
on the basis of the foregoing, an active investigation of Brothman
was intituted. He was born August 15, 1913, at New York City, is married,
and resides at L108 42nd Street, Sunnyside, Dang Island. He wasarmerly
employed by the Hendrick Mamzfaotnring Company, 39 Church Street, NewYork City,
and left this organization in July. 1942, to become Vice President of the Chenmrg
Design corporation, 420 Lexington Avenue, New York City. About August l, 191.4,
Brothman resigned from this organization and organized the firm of Abraham
Brothman and Associates, Room 1606, LL4 Bast 32nd Street, New York Glw. ID:
connection with this firm, he did work for the Bridgeport Brass company and the
Graver Tank anufacturing company.
Brottnan was interviewed in l94'7 and identified a photograph of
Golos, but claimed not to remember his name. He stated that Golos had come to
him" in 1938 or 1939, advising that he had contacts with the Russian Government
for Brothman if Brothmao would turn over to him blueprints of certain lroducts
that Brothman was working on at the time. Thereafter, Brothman said that Golos ,
visited his office on several occasions and later introduced him to a woman who
used the name of Helen. Brothman identied this woman as Elizabeth T. Bentley-
Brothman stated that subsequently he-was contacted by an individual by the name
of Harry Gold who said that he represented Golos. - He said that both Bentley and
Gold picked up blueprints for Golos which were sometimes returned to him and
sometime not. He said that Gold made his last pickup of blueprints in late
1941 or early 1942. -It developed during the interview that Gold was than
employed by Brothmn as a chemist. A
, An interview was conducted with Harry Gold on Hey 29, 1947, in which
he stated that he had been employed by the Pennsylvania Sugar Company in '
Philadelphia and had met one Carter Hoodleq whose father was an official of
the comparw. He said that I-loodleintroduced him to a man by the name of
IGolish,I whom he subsequently identified through a photograph as Jacob Golos,
and after meeting Golos, agreed to contact Brothman and obtain from him blue-
prints for Golos. Gold claims that he did meet Brothman and contacted him on

Mrs. EEIhil4iN_ st s that she is of the opinion that KLAUS FUCHS pro-hably knew that mm es in the Congmunist arty, On the other
hand, she feels sq al y certain that BOB ssnrmm never knew of ,KLAUB -
FUCHS meinbership in the Communist Party in .Germanyi_n 1933 and 1934.
Her latter recollection is predicated on the thought that there had never
been any occasion to discuss FUCHS political sctiyity. in the-IiEIN_mLAN .

sosssr on February 10. 1950. finally admitted that he had been,
associated with the Comuniet_Party at Swarthmore College 1111935 to 1938,
and at Cambridge, assaohusetta, £'ron_1- 1s_sa 1:0 1949. he noted that his ~--
party association and activity in Cambridge, Massachusetts, was of a - _
limited nature, partially because he could nevezj adjust_.his on personality
to that of the pm-tycnembers in the branch to phioh he had been assigned,
and partially because during the years 1944 s.nd'l945, he had been working
on a night shift at'the.Genera1 Electric Plant in Lynn, hhssaohusetts,
and hhd little opportunity forapsrty associations In_addition,,hhss ., _
wife had always .disappro'ved.oi his nembershiplin the Communist -Party,
largely on religious grounds, and as their hone 11-fe, at best, was
never pleasant, inactivity in the Uomnunist was Jtill another
way of lessening strained relations. HEHIEHAN claims. that he has. been
very inactive in the Gomuniat Party in recent years, attending ,a1inost-:
no meetings, and further that no nesting! have occurred inhie home '

DETAILS: onfidential Informant T-1, of known re]iabi1ity,§dviaed that
February 2, 1950, that EH11 JULIUS KLAUS FUCHS a ted
to English authorities in an interview, that he was re- i
cruited in 19241 at his own instigation through the intro- t Q
duction of a Communist friend whose name he had not made available. His '
first contact in England was a man of Russian nationality who as of February 2,
1950, was not identified, but who is believed to be a member of the Soviet T
Embassy in En a d. His ssmnd contact in_:§ngland was a woman of foreignnationalityjw w ,_
FUCHS stated that his contact with the Soviets while he was in the 1
United States was carried out through the medium of one man. As oi February Z,
1950, this man had not been identified and FUCHS maintained that he did knowhis nationality. He did state that the contact was %£'14 nuclear physicist
but had some knowledge of chemistry and engineering -
Confidential Informant T-1 believed that E11 meetings were carried
on in street corners and that four such meetings took place in New York during
191414. A further meeting was arranged for Boston, Massachusetts, during the
Christmas season, l9!.;h, but FUCHS did not show for this meeting. -_ One or two
meetings took place in Boston between February 13 and 22, 19h5, while another
took place in Santa Fe, New hleacico, in June, 19115, and still a further meeting
also occurred a later date in Santa Fe, exact date not available. FUCHSthird contact §ter hi rw the United States was a man, -possibly a Russian. //I is/A?/3 ;.;31l?.'_4/I PRU-MC
FUCHS as of February 2, io, had maintained that ROB§_Bj1f_1-IE_Ii~l_.F;11@-1AI92§
was not implicated. He had stated, however, that his sisterfl?RISTEL 1-EEINELEAN,
of Cambridge, Massachusetts, who was evidently an active und_c6v'ér"'Con1muni'st
in Germany, may have witnessed FUCHS meeting with his United States contact in i
Boston, and may hav deduced that this was a continuation of FUCHS! underground work in Germany. Z
On February 6, 1950, Confidential Informant T-1 furthezgmdvised thaton Qanuary 27, 1950, in a preliminary interrogation which led up to FUCHS
sta ement of that date, FUCHS steadfastly denied any acts of espionage for a
long period. Finally, he admitted because of interstruggle, that he was faced
with in-vo alternatives: first, to admit his misdeeds and through this purg
oi his soul, attempt to remain at Harwell, the British atomic energy center

In his college days, FUCHS was originally a socialist. He changed
over to the Communist Party when the Nazis came into power in Prussia, He
is still a convinced Communist but does not now agree with the present policies
and practices of the Soviet Union. He left Germany in the early 193015and came to Great Britain. He was interned for a period of time at the out- e
break of e war. Upon his release from interment, he went to work for a 4/

living with Professor PEIERLS. He changed his residence to another address llin Birmingham and thereafter, his__contect and place of meeting were chmged-Z!

In all, FUCHS states he had about eight meetings in the United States
with this contact whom he neither then namedmr described. He had stated,
however, that the contact was totally unknown to him other than as a contact
for the transmittal oi espionage information. He had expressed the opinion,however, that the contact m xjaxkhave been a chemist or engineer but wasdefinitely not a ptnrsicistfa

FUCHS said that the rst meeting in New York was February or March,
l9l4.h, and that there were about three other meetings in New York prior to the$
. time he left for Ins Alamos in the summer of 19104. His next contact in the
United States was in Boston, Massachusetts, in February, 19115, when he had
two such meetings within a few days of each other. The next time he met with
this man was in June, 19115, in Santa Fe, New Mexico. FUCHS fixes this date
because it was prior to the explosion of the test bomb. His last meeting n [1,the United States was in the fall of 19115, again in Santa Fe New lleacioo-.4?!E 0!//M/A/A 0

Fcs, were very infrequent and stopped altogether in February or March, 19149.
By this time, FUCHS stated he was convinced that his scientific associates
at Harwell were genuine people; that he enjoyed the British way of e andhad fallen out of sympathy with t t programs and policies.c5]':T|!_,
While in the United States, FUCHS said he had no hesitation in giving
to his contact all the information he had, although he tried to concentrate
on giving the information about the results ef his own work. In the United§92St-ates while at Les Al-'7~LIJ1.0S, he gave information about the principle of the
design oi the plutonium bomb. However, when he was placed in a responsib eposition at Harwell, he claims he started to hold out on the Russians.

however, that the possibilities of the H bomb had been the subject of dis-
cussion at Ios Alamos during the time FUCHS was there. Also PEBRIN stated .
anything about the practical production of the plutonium" bomb or about the X that FUCHS was a theoretical plwsicist in the weapon eld and did not know
problems of production of isotope separation}: "J2-==_-~.=-*~7Further, he stated rnat% would probably be impossible to locate -
or identify am material which mig have been passed by FUCHS to his contacts
which was not authorized to be in FUCI-15' possession. He further indicated
that it was his impression that FUCHS, while at Los Alamos, prepared hand-
written notes on matters within his lglowledge which were transmitted to his
contact. PERRIN pointed out that plutonium was manufactured at one place in
the atomic enel-gr establishment which did not have British scientists in -
residence. He also observed that Soviets at the time of their atomic
explosion must have had a plutonium iiile and was ve ositive in statingthat FUCHS did not possess such p1j,<>§}¥5>§io_n lemon-h&992K
with regard to FUCHS activity at the 19117 Declassificaticn Con-
ference which was held in Chicago, Illinois, PERRIN advised that FUCHS was
a model delegate with a strong sense ='-of security. With regard to the atomic
atomic explosion because he did not kfnow that they had the industrial capacity yq bomb, FUCHS is alleged to have stated that he was surprised at the Soviet
for it although they undoubtedly had the scientific and theoretical ability.
Confidential Informant T-l furnished the results of a hearing held
for FUCHS at Bow Street magistrates Court, Fe ruary 10, 1950, from which
some excerpts are set forth hereinafter: '1
Mr. CHRISMAS HUMPHRIES, Director of Public Prosecutions, read the
charges against FUCI-IS,both under Section 1.1 c! of the Official Secrets-Act,
The first charge is that on a day in 191;! for a purpose prejudicial

V The prosecutor stated that when FUCHS first entered atomic research
which was before he was naturalized a British citizen! he signed the usual
security undertaking. He did this;again in 19hh and is that document, it was
made perfectly clear to FUCHS how security minded he must be and understanding
it, he signed it. "It is now clear that such an"o_ath_of allegiance meantnothing whatsoeve1 - t a man whose,mind was irrevocably Wedded to Communistprinciples. " $ J u 7 ~~{ ..
After deciding to inform Russia and establishing contact through
another member of the Communist Party, FUCHS-confessed that there was a con-
tinuous passing of information relating tohatomic research at irregular but

commenced on his ovm initiative withqut anyapproaoh having been made to him.

Hrs. HEIIIEHAN stated that she saw her brother, EMIL JULIUS KLAUS FUCHS
for a few days during the Christmas holidays of 1933 and that she heard from
other members of the family in 193b, that he had been compelled to resign from
the University at Kiel because of his political activity. She believed that
all of his scholastic records had been stamped, "This man is a Communist", and
as a political fugitive, he walked across the Germanlaorders to France.
In 1935, when she was enreute to this country, she spent two days
with her brother in Paris and did not hear from hm again until l9b3 and then
indirectly. In early 19b5, she states that FUCHS wrote that he'eas coming
to visit them. She recalls that FUCHS visited the HEINENAN home sometime in
February, 1955, during which visit he spent two or three days in her home.
It is her recollection that thereafter, he was a frequent visitor
in l9hS for one-day periods, that is, he had arrived in the morning and de-
parted in the afternoon or evening. She recalled that FUCHS only friend
in lambridge was e man named E§§§§gE whom she believed had worked with FUCHS
at Los Alamos. Upon the termination of the los Alamos work, DEUTSCH came
to the Kessachusetts Institute of Technology as a faculty member.
It is to be noted that the Los Alamos records reflect that FUCHS
was visiting in Cambridge, Nassachusetts, from February ll to 25, l9hS.
I.t:'s. I-IEIIIELAN stated that approximately three weeks before FUCHS arrived in
Cambridge in February, 19b5, an unidentified ohcmst called at her home and
inquired as to whether or not FUCHS had arrived. This unknown man intro-
duced himself to her as a chemist who had worked with her brother.
lie. HEIKEHAN is under the impression the unknown man had worked with FUCHS
at Los Llamas, although detailed questioning on this point revealed there
is no basis now known to her for this assumption. -
On the occasion of this first visit, the unknown man visited with
Ere. HEINEMAN and her children and she gave him lunch. She informed this
man of the approximate time of her brother's arrival in Cambridge, Hassachusetts
Es. HEINEHAN stated that there was no one at her home except the children
and the unknown person on this occasion.
On the second day of rucnsr visit to the rmnremr home in February,
19b5, this same unknown man again rang her doorbell. She stated that this

children and to her best recollection a book entitled, "Mrs. Palmems Honeynfor her. ,
Mrs. HIEINEL-'..N does not know whether the chemist received anything
from FUCHS. or gave him anything, but she was under the impression that the
unlmown man was again between trains and left shortly after his arrival.
Sometime in the following few months, this same unknown man again
stopped at her home and made inquiry. as to whether FUCHS might visit her.
She had no recollection of an impending visit from FUCHS and so advised the
