ESPIONAGE - R 
PJiRJURI 



A review has been mad 4 of the Bureau files la the above- 
captioned matter and the following leads requesting additional 
Investigative attention are being set forth for your office as 
well as the other offices receiving copies of this letter. It will 
be noted that these leads are for the purpose of obtaining additional 
corroborative evidence for use in the forthcoming perjury trial against 
subject Perl, as well as to develop information as to the extent of 
Perl's espionage activities In behalf of the Rosenberg Espionage network. 



In:itheT;roiJart*.a»f SA John P. Buscher dated at Washington, D. C 
September 21, 1950, it is noted that on page 7 there is set forth a list 
of documents and secret reports which wire made available to Perl by the 
National Advisory Committee for Aeronautics. It is particularly noted 
that on December??, 1948, a confidential document entitled "Effects of 
Boundary Layrr C-ntrol on Airplane Range” by L. E. Root of the Rand 
Corporation was made available to Perl. In this respect, you will recall 
Groenglass* statement that Rosenberg informed him on one occasion that he 


Rosenberg, had knowledge of a secret project developed In upstate New York 
involving the constructional* a- sky platform whijh wap /ie scribed as 4. t j

vehicle to bo suspended in the atmosphere at a point where gravity 
eeases to exist. Inasmuch as this project has been Identified as the 
highly secret "Hand Project ," it is requested that the Washington 
Field office discuss this matter with an appropriate official of NACA 
to determine whether the aforementioned document may hove bed ary 
pertinence to the previously described sky platform, (ibid 129, page 6) 

On page 3 2 of the report of 3A John B. O'Donoghue dated at 
Cleveland September 27, 1950, there is quoted £ memorandum submitted by 
Perl on November 9# 1944, explaining his having exceeded the maximum 
amount of leave granted by a period of 8 days. It is noted that Perl 
claimed this excessive amount of leave .was necessary by reeson of his 
marriage and the ensuing dlffiouity he experienced in locating a suitable 
place to live. It is further noted that daring an 1? terview with Pari 
as reflected in the report of SA Vincent J. Cahill dated at New York 
December 15, 1950, Pori advised that during his period of leavo between 
Augflet 28 and September 2, 1944, he was busily engaged in the prararation 
of an apartment at 1516 East 120th Street, Cleveland, Ohio, in anticip*- 
tion of the arrival of Henrietta Savldge. (ibid. 147, page 32j 187, page 38) 

. With respect to the above, it. definitely appears that neither . 
of his statements .is,' true and that same were made by Perl In order to 
cover up his frequent trips to New York City in connection with his 
espionage activities. Inasmuch as some proof of tho rfalsity of these 
statements may bo nocessary during tho course of the forthcoming trial 
particularly with respect to Rlltcher’e testimony as to his September,, 

1944, dinner meting with Perl in New York City, it is desired that the 
Cleveland office obtain detailed information concerning the places of 
residence of Perl in Cleveland during 1944* As to each of his places of 
residence, the date of rental, the date of occunancy, and the date of 
expiration of lease or departure should be ascertained. With respect to 
the apartment at 1516 East J20th Street, appropriate inquiry should be 
made for the purpose of developing any information concerning the re- 
decorating of this apartment which may have been done by Perl prior to his 
occupancy.

«D 



The above information a s to Perl's date of occupancy of various 
apartments in Cleveland during 1944 tiay also prove to be of some value in 
further developing evidonce as to the close contact and association that 
existed between Vorton Sobell and Perl. You will recall that In Uay, 1944# 
Sobell, in executing a 0. 3. Navy fora at Oeneral Electric# Schenectady# 
Hew York# gave as a reference William Vuttorperl# whoso address was set . 
forth aa 16608 Uadlson Avenue# Cleveland# Ohio. It has been determined 
through the Bureau's Investigation that, during the year 1944# P«rl 
resided at the following 3 different addresses! 11703 Wadlson Avenue# 

16808 Uadi son Avenue# 1516 East 120th Street. The exact date of Perl'a 
occupancy of the apartment at 16608 Had is on Avenue might serve to show the 
very current nature of Perl's contact with Sobell at the time Sobell 
executed the Havy form. (ibid 231) 


On page 33 of the report of SA. John B. O'Donoghue dated at 
Cleveland September 27# 1950# there was set forth a memorandum submitted 
by Abo Silversteln dated February 23# 1945# recommending a promotion for 
Perl. This memorandum described Pori's duties as theoretical and aprlled 
research relating to the problems of jet propulsion. It was specifically 
mentioned in this memorandum t!-at Perl had prepared papers in the field of 
potential flow among whl oh were listed the following r 


(g) "Some Effects of Compressibility of the Flow through 

Fans and Turbines" 

(h) "A General Representation of Axial Flow Fans and 

Turbines.® 


The report of SA Maurice W. Corcoran dated at Kew York 10-26-50 
sets forth the results of a physical surveillance on Perl* It raa noted 
on page 54 of this report that Perl was observed on September 13, 1950, 
leaving the home of his parents with miscellaneous pieces of baggage and 
proceeding directly to the Pupin Laboratory at Columbia University* Further, 
that he was later observed taking this baggage to the address 610 West 
110th Street, Mew York City* ••= : . 

(ibid 114, page 64) 

Inasmuch as a search of the residence or Perl at the time of 
hla arrest failed to reveal any pipers or documents of pertinence to his 
possible espionage activities, it is suggested for the consideration of the 
New York office that Perl may have retainod certain of his personal and 
confidential scientific papers at the Pupin Laboratory, the contents of w 
which may be readily ascertained through an appropriate discreet source* 

s On page 57 of SA Corcoran's report, the contents of a postal 
card sent by Perl to his sister, Mrs. AnmBlum, on 11-27-39 were set out as 
follows t 


"I am writing to a frlond of mine with this nail to arrange 
having it typed* He's a classmate and has done this sort 
of thing before* Would you mind lending your typewriter 
if need be?" 

(ibid 164, page 52) 



From other correspondence of Perl, it is possible he may 
here been referring to hie thesis containing various mathematical 
, , equations* However, as you are aware, Perl was, at the time of this 

communication, stationed at the NACA Laboratory, Langley Field, Virginia, 
and, according to Max Elitchor, was known to have maintained correspondence 
with Sobell. It is particularly noted that in Per 1*3 subsequent letter to 
Mrs. Blum on February 4, 1940, be makes specific reference to a friend, 
"Sobell, " who is believed to be Morton Sobell, 

, In vlewof the foregoing, it is requested that the New fork 

Va office relntervlew Mrs, Blum on the basis of Perl's card of November 27, 
jO*' 1939, to definitely establish the nature, of the copy work to which she . 

^ . understood Perl was referring and whether anyone actually did borrow or 

f contact her with view of borrowing her typewriter. 

On page 60 of this report, Perl*s letter to hie sister, Mrs, 

Blum, dated October 3, 1944, was quoted. It is noted that this letter 
contains .the following information * 

"A friend of mine just quit his {2600,00 a year job to go 


back to school and study radio, 0 


(ibid 164, page 60) 


There is little question but that Perl was making reference 
to Sobell, inasmuch as Sobell is known to have resigned his position with 
the Bureau of Ordnance on October 1, 1944, and according to Elitcher was 
earning {2600,00 at the time. In addition, it is known that Sobell there- 
after continued hla studies at the University of Michigan, taking oourses 
in radio engineering, 

* This letter which, is included in the prosecutive summary prepared 
In this case is considered of importance by reason of its corroborative 
value to Klitoher 's testimony indicating tint ha, Elitcher, while living 
with Sobell in Washington, D, C*, had observed correspondence between Perl 
and Sobell, It is believed that this letter provides rather conclusive 
proof of the close contaot which was maintained between the two in that PerjL 


1 ; . . t ' V * A ‘

although stationed at Langley Field, Virginia, wascognisantof Sobell's „ 

" V reaignationfrom the Buroau of Ordnance in Washington, D. C. , within a 
/^period of 3 days from the time that this resignation was actually effective* 
f ^ The New York office should' therefore determine whether the United States 
J>' Attorney is desirous of having appropriate Bureau of Ordnance records 
^ verifying the date of Sobell's resignation and the amount of his salary, 
as well as University of Michigan records reflecting Sobell's study of 
radio engineering in that institution, available for the forthcoming Perl 
trial* In the event such testimony Is desired. Immediate steps should be 
taken to determine the identity and address of proper officials who could 
Introduce such records, so that this Information can be made available to 
the United States Attorney for his assistance in the issuance of a subpoena 
duces tecum* , 

s. 

In the case entitled "Nathan Sussman, was; Espionage - ft," NT file 
65-15399, the report of SA Bert S. Taylor dated at New York May 2, 1951, 
seta forth the results of an interview with subject Sussman in March, 1951* 

It is noted that on page 4 of this report, Sussman la Indicated as having 
stated that he recalled that Morton Sobell, William Danziger, Max Elitcher, 
and William Perl were all members of the ICL group which he joined at CCNY* 
Further, according to Sussman, that these nestings were held at the Karl 
••• Mane House on the CCNY campus on a weekly or semimonthly basis* ( 100-331124-46 


On page 10 of this report, it was mentioned that Stanley Robert 
Rich, upon interview on September 5, 1950, advised that he had become a 
member of the Steinmot* Club at CCNY, which group became affiliated with 
the TCL. He further recalled his attendance at closed meetings of the YCL, 
which meetings were likewise attended by Julius Rosenberg, Sobell, Elitcher, 
Dansiger, and Sussman* (100-337124-46) 



The testimony of Sussman as to Perl's alleged YCL activities should 
be immediately brought to the attention of the United States Attorney for his 
possible use in connection with the forthcoming perjury trial. However, as 
you are aware, the probative weight of Sussman 'e testimony in this regard 
might be somewhat weakened if the government is unable to corroborate this 
testimony through Elitcher, Rich and Danziger, who were alleged to have been 
members of the same ICL group at CCNY. 





A review of the results of the interview of Rich on August 28, 

1950, reflected that Rich admitted knowing '."illiam Perl at CCNY and 
considered him to be sympathetic with the Communist cause. Rich stated, 
however, that he could not recall any definite association between Perl 
and the YCL at CCNY. It was Rich ' 3 recollection that Perl would have 
known Danziger, Sobell, and Elitcher, who were classmates in that institution. 
On the basis of the recent statement by Sussman, the Boston division is being 
requested to recontact Rich in an effort to determine whether he is able to 
recall additional details concerning the YCL group at CCNY and the alleged 
connection of Perl with that group. 


You are also, aware that Elitcher, when interviewed on September 13, 
1950, advised that the name of Steinmetz Club sounded familiar to him but 
he had no recollection that it was a club on the CCNY campus during the 
last two years of his attendance at that school. Elitcher stated that' the 
Steinmetz Club was probably the YCL Unit at CCNY and that it was his recol- 
lection that around January, 1938, he had been solicited to join the YCL 
by either Rosenberg or Rich. He claimed, however, that he did not recall 
whether he actually joined this club but he remembered attending several 
meetings of the YCL where there were about 12 persons in attendance, among 
whom he knew were more than, a few engineers who had graduated from CCNY. 


Further, it ..will be recalled t^iStf'T^n'zrl'glri ^ upon interview on 
October 25, 1950> flatly denied that he had ever been a member of the YCL 
or the Steinmetz Club at CCNY or ary group or unit affiliated with the CP. 

It is requested that the New Yo rl<P office on the basis of the 
additional information obtained through the recent interview with Sussman, 
agatin interrogate Elitcher as well as Danziger in an effort to determine 
whether they might recall additional details to that previously furnished 
by them which might corroborate the allegation as to Perl's connection with 
the YCL at CCNY. For the information of the New York office, the Bureau's 
Legal Attache in Paris, France, is being requested to reinterview Samuel . 
Perl. The purpose of this reinterview is to specifically question him con- 




corning his being present at the dinner party at the Bird-in-Hand 
restaurant in New Tork City In September, 1944, which affair was at* 
tended by Rosenberg, Max and Helene Elitcher, Ruth Alscher, and his 
brother, William. He la further to be questioned ooncerning the 
subsequent visit by this group at the apartment of Joel Barr's parents 
and the apartment of A1 Sarant. Perl is likewise to be interrogated 
concerning his whereabouts during the period of his furlough from Camp 
Breekenrldge, Kentucky, during the period from July 22 to August 4, 1944, 
as well as to his whereabouts during the period from September 9 to 
Septentoer 14, 1944, when, according to the Any records, he was to transfer 
from Camp Breekenrldge, Kentucty, to Port Leonard Wood, Missouri* ^ 

The above investigation should be given the irsnadiate attention 
of your office as well as the other offices receiving copies of this letter, 
in view of the Imminence of the Pari trial whioh is expected to be held in 
New Tork during June, 1951*

GEORGE PAGE, Engineer, Curtiss-Bright Corp.,

advised he first heard of a unit similar to TG-100 
being tested on a Ryan Aircraft plane in San 
Diego, Cal. in late 191*3 or early. 1914*# PAGE 
explained that Curtiss -Wright Corp. worked with 
TG-100 in Columbus, Ohio, in early 1946, and 
abandoned project as unsuccessful. PAGE recalled 
that turbo-unit used at Columbus had General 
Electric Serial No. 6 or 7. PAGE' advised that 
a Mr. SALMON was probably in charge of the turbo- 
unit tests made at Ryan Aircraft in San Diego,

AT COLUMBUS . OHIO 


Mr. GEORGE PAGE, Engineer, Curtiss-Wright Corporation, 
is still in the employ of that company and is working in Columbus, Ohio. Since 
his return from England he has been working at the North American Aircraft 
Plant for Curtiss-Bright and will continue on this work until North American 
Aircraft has completely absorbed all of the Curtiss-Bright work. According 

to PAGE, he should be in Columbus until the fall of 1951* , 

y , 

PAGE explained that he first heard of a turbo-prop unit 
such as the TG-100 in late 1943 or early 1944. He said that he had heard that 
such a unit was the subject of tests on an aircraft at San Diego, California. 

S DESTROYEb . 







He recalled that, the turbo-unit work was being done at the Ryan aircraft 
Plant in that California city. PAGE said that he was in St. Louis, Missouri, 

v/hen he learned this information and thought it .vas common knowledge in the 

indus try _that_such -experiments were- going _ on in - Califdrrii'a.'' PAGE "was quite 
certain that this turbo-prop unit rras identical vrith the 'IC-IOO. 

Mr. PAGE advised the Curtiss-Bright plants aid not 
work on the TG-lOO until early 19li6. He stated that Curtiss-Bright had anticipated 
that they would work on the project much sooner but the General Electric Com- 
pany was greatly delayed in shipping the TG-100. lie said they had planned to 
work on it at St. Louis, Missouri, however, the St. Louis plant closed in June 
of 19U5 and operations were moved to Buffalo, Mew York. PAGE recalled that 
while in Buffalo he made a plane trip to Schenectady, New York, attempting to 
expedite the delivery of the TG-100. He said that the Buffalo Plant closed late 
in 19U?» and the operations were moved to Columbus, Ohio. It was, according 
to PAGE, early in 19U6 that the TG-100 unit arrived in Columbus.. He said .that • 
experiments and tests- were then started by installing the unit on one side of 
a C-U6, twin engine cargo-type plane. He stated the experiments and tests were 
not successful and the plane was never flown for a tost. PAGE recalled that the 
serial number of the TG-100 unit that was used in the tests was either y’6 or 
#7, which indicated to him that several units had been previously manufactured 
by the General Electric Company. He said the TG-100 v.?<t the only unit he, per- 
sonally, had ever worked with. FACE could not recall anything concerning the 
use of the TG-100 in a high altitude jot fighter plane, knov/n as the XP-61. 

' ■ ' ' PAGE was asked if he knew any aero engineers in the Ryan 
Aircraft Plant who would have knowledge of the turbo tests supposedly conducted 
on a Ryan plane during 19l'3 or 19UU. PAGE said he thought the Chief Engineer 

was a man named SALMON at that particular time but did not know if he was 

still with the Ryan concern.

Will contact the Ryan Aircraft Company and attest to locate the 

Mr. SALMON mentioned by GEORGE PAGE, and, after a thorough 

1 check of the office indices, consider the advisability of inter- 

viewing him concerning his knowledge of the history of the turbo- 
unit TG-100, which may possibly have been tested in a Ryan plane 
during 19h3 or early 19Ur. 

Will, if it is determined that SALMON is now in employment elsewhere, 
set out appropriate leads so that he may be located and interviewed. 


CINCINNATI OFFICE

TG-100 or the I-UO. 


Will also contact the appropriate officer at the Aircraft Projects

In connection with this review, it is believed Vivian

- the operations of the Rosenberg apparatus . Pataki was utilised as a 
t kcourier to contact Perl in Cleveland , Ohio, and furnish him with money 
^ and instructions on how to flee the U.S. She has admitted making this 
trip to Cleve land upon instruct ions of an unknown man . She has refused 
: to identify this person and has refused to make any atten.pt of an 
identification . She was formerly the fiancee of Joel Barr, member of 
f*the Rosenberg ring who left the United States in 1943. She was a close 
'[associate of Alfred Sarant who fled the U.S. in 1950 after preliminary 
? questi oning by bureau Agents . She was also a close friend of Jul

Reference ie made to the report of SA JOHN V. LEWIS, Nev York, dated 
June 26, 1950» In the case captioned "DAVID GREENGLASS, was, Espionage - R, " 

On Page 32 of this report it is reflected that GREENGLASS advised that his wife 
had come to Albuquerque to live in about February 19^5- She had difficulty in 
finding a place to live and for a time shortly after her arrival in Albuquerque 
she resided on Coal Street, Albuquerque, with the wife of a friend of DA VII *6,, 
whose last name was SPINDEL. GREENGLASS further advised that while hiB wife was 
living at Albuquerque, he bought a car in partnership with SPINDEL and a tall 
red-headed fellow, whose name he could not recall. He believes that this car was 
a Dodge and the car was registered to WILLIAM SPINDEL. 


, When Interviewed on June l6, 1950, Mrs. RUTH GREENGLASS stated that no 

one visited her while she was in Albuquerque other than wives of G.I.s who were 
stationed at the Army Base with her husband and people that she worked with. She 
named some of her visitors as SPINDEL GORMAN, CHARLIE SCHRODER, RAUMGARTEN, and

On Page 76 of referenced report it is noticed that in a list of names 
whi elf had^ppeared - iha — siSll - tel^hohe - notebbok^vhich - was - found inGREENGLASS ' 
apartment, was the name WILLIAM SPINDEL, 613 West Coal, Albuquerque, New Mexico. 

On Page 50 and 51 of referenced report it is reported that a letter 
from T-5, D. GREENGLASS, Santa Fe, New Mexico, to Mrs. R. GREENGLASS, New York 
City, dated October 4, 1944, stated as follows: 

"Well, today I worked kinds hard and am pretty tired, but Instead of 
taking this leisurely I am going to dinner with HY and BILL at 
EMANUEL and ETHEL'S home (you know the nice people I met). I hope 
that they have something good to eat since I am quite hungary. ” 

It is suggested that the "BILL" mentioned in this letter may be identica 
with WILLIAM SPINDEL and it appears that SPINDEL and GREENGLASS may have been 
acquainted as early as October 4, 1944. 

On Page 52 of this report, it is stated that a letter from T-5, D. 
GREENGLASS to Mrs. R. GREENGLASS, dated January 28, 1945, stated as follows: 

"I was over to BILL'S house last night for supper and this morning 
for breakfast -- besides this HY and I have not had much social 
activity - - - BILL'S wife is a very nice woman, pretty, and husky 
voice and about es sloppy-dressed as BILL so that they make a good 
couple. Make no mistake about it, she has brains too. You'll meet 
her.” 

SARAH LEW SPINDEL applied for a Job at the University of California, 

Los Alamos, New Mexico, on December 12, 1944, giving as her address 824 North 
Fifth Street, Albuquerque, New Mexico. 

It appears from the last letter quoted above that DAVID GREENGLASS may 
have been at the SPINDEL home for supper and breakfast in Albuquerque, New Mexico, 
January 27, 26, 1945* GREENGLASS mentions BILL in this letter and states that 
hi 8 wife will meet BILL'S wife. This letter might be interpreted to mean that 
Mrs. GREENGLASS had already met BILL. WILLIAM SPINDEL was on leave from the Los 
Alamos Project from October 15, 1944, to November 4, 1944. As his home was in 
Brooklyn, New York, it is probable that he made a trip to Brooklyn at that time, 
as he had known DAVID GREENGLASS prior to that time at Los Alamos. He may have 
met RUTH GREENGLASS in Brooklyn during this furlough. 



Id further support of the theory that Mrs. GREENGLASS nay have contacted 
WTLLIAM SPINBEL,in addition to her husband vhen she came to Albuquerque In the 
latter part of Bov ember 194L. it la pointed out that on December 11, 19^» WILLIAM 
SPINDEL wrote a letter to Brooklyn College in an attempt to obtain his B.A. Degree. 
It eppears that SPINEEL's purpose in trying to get his degree at that time was to 
be able to obtain aihite badge at Los Alamos which would entitle him to attend 
colloquium meetings at Los AlamoB at which meetings highly classified subjects 
concerning the over-all work at Los Alamos Project were discussed. It may be 
significant that WILLIAM SPINDEL attempted to obtain additional access to classi- 
fied information at this particular time.

I called Inspector DSU.'ONT of the Bureau at 1:15 today, to ascertain 
whether there had been any developments with regard to ourtel of the fifteenth

department with regard to this matter, and would send it over today, and that • 
probably I’ondav a decision would be reached. O I A.

our. belief that we should first attempt to break him on an interview in order’ 
to obtain his story as to his implications in espionage/VS S£T~_ccfT /* toiTa.

conspiracy charge. I told him that we would not place out-going stops, in p'-m .
