Dear Miss Tinberg: 

- - - - --------------------

February 12, 1948 

Thank you very much for your letter of February 9. I 

would, indeed, very much like to have for my own collection 

a eopy of publications 15 to 22 bound in one volume and will 

be glad to pay whatever postage or express charges are 

involved since this would be for my personal use. However, 

I am sure tbat our library would also appreciate one bound 

volume and I·v111 be glad to pay the express charges on two 

copies, if you can spare two, one of which I will then 

deposit in our library. 

I appreciate your sending me the inf'orma..tion concerning Miss Jensen, and I am writing her today. I believe that 

you are correct 1n stating th.at everything dealing with the 

Shakespeare problem vas turned over to the Library of 

Congress, but the records for which I am seeking vere not 

of that category. It is possible that Mrs. Tyzzer can 

throw some light on the matter. 

Thanking you very much for your courtesy, I am, 

Sincerely yours, 

William F. Friedman

Dear Mr. Friedman: 

Thank 70u tor your letter of the 6th. 

I em sorry that the publications ref erred to in 1111' 

previous letter were not what you wanted. You 

mention, however, that you would like two or three 

copies each of Publications #15, #16 and #17. The 

only copies we have are bound in one volume, 

"Publications, 15-22 Incl.", and we shall be glad 

to send this vol'U1118 to you, it :you so desire. · 

Cora jensen1a married name is Mt-a. Fr~ Tyzzer, 

end her address, 1222 James Street, Geneva, Illinois. 

She, perhaps, would be able to help :you, as she was 

here at Riverbank at the time of Mrs. Fabyan'a death. 

Mr understanding is that everything was turned over 

to the Librar:y of Congress end this is the inf'ormation 

given to me last week b,r one of the Trustees ot the 

FabJ'an Estate. He also served as one ot the Emcutors 

ot Mt-a. Fab:yen1s Will. No doubt, the papers to which 

you rater have long since been destro:yed, as all that 

we have at RiverbBDk now are the Publications mentioned 

in rq previous letter. 

I do wish that I could be or more help to you, and 

hope that Ml"s. Tyzzer mq be able to give :you the 

desired information. 

Sincere'.q yours,

Dear Miss Tinberg: 

February 6, 1948 

Thank you very much for your letter of 2 February. 

I was indeed unaware of Miss Cumming's death and waa 

quite shocked to learn of the manner in wb1ch it occurred. 

The publications to which you refer are not the things I bad in mind. However, if you can spare tvo or three 

copies each of Publications 15, 16, and 17, I would be moat 

appreciative. I have copies of the other publications listed in your letter and thank you for the offer to send 

them. 

can you tell me what the ~ormer Cora Jensen's married 

name is and where I might address a letter to her? She 

perhaps can tell me the answer to a question or two concerning the disposition that vas made of the papers I am trying 

to locate .. 

Incidentally, I have gone thoroughly over the Fabyan Collection at the Library of Congress and am sure no such 

papers as I am seeking are among them. 

Thanking you again for your courtesy, I am, 

Sincerely yours,

Dear Ml-. Friedmmu 

Your letter ot JamJ8rJ' 22m1, addressed to Mias Cnrmning, 

has been received. 

You appare~ do not know that Miss C1mn1ng was killed 

in an accident on Mq ll, 1946. She was returning to 

Riverbank Lodge from Genna in a car with two house 

guests, and the car was struck by a fast North Western 

train at the station crossing here. All three occupants 

ot the car were killed. · 

As 70U doubtless know, all of the Riverbank Publications 

were turned over to the Library of Congress after Ml-s. , Fabyan's death. The government at the time arrm:iged 

to have Mi-. Walter Hill or Chicago do the neceasar.r 

work or examining the books, etc., as well as packing 

them tor shipnant to Washington. 

We do, however, have bound copies ot the followings 

''Methods for the Solution of Ciphers, 

Publications, 15-22 Incl., Riverbank 

Laboratories, Department of Ciphers, Riverbank--Geneva, m.n 

"Memorization .Methods, Specif':lcal.l.y

Applicability to Codes and Topographic 

Material, Publication No. 75, 1919"

in Concealed Writing and Jmages, Publication
