Dear Cora: 

March 9, 1948 

I am much indebted to you for your letter of 24 FebrU9.ry, despite the fact that it gives no clue to the papers I'd 

lilce to see turn up. They were probably destroyed, just a.s 

you indicate. 

Yes, ve had a very nice visit from Fred Kranz. I ran 

into hi.s son-in-law in the Navy and that's how we got together. It was very nice to renew acquaintance after so 

many years. 

By all means, if you and your husbanC. come to Washington 

you must visit with us and we, too, should we be in your vicinity, will look you up. 

Thanking you again and hoping you are fully recovered 

from your cold, I am, 

Sincerely yours, 

William F. Friedman

Dear Billy: 

Feb. 24, 1948 

It was a plee.sant surprise to receive 

your letter on February 16. I am just recovering froc the flu and a miserable sinus cold, 

hence the delay in respo~ding to yot1.r letter. 

I wish I could give you sane definite 

information regarding the disposition of the 

cipher ms.terie.l to which you refer, but unfortunately I cannot. The papers were kept intact 

until after the Colonel's death. Miss Cumming made the final disposition of the papers when 

I v1a.s not t~ere. I· really believe they were 

destroyed as I believe l:iss Cur.iming did not 

wc.nt to ha.ve them circulated. At lee.st, every- thir..(i of that ne.ture he.s been clef.red out at 

Riverbank, and Miss Tinberg said she had nothing 

to do with it. 

?i~iss Cui:UD.ing' s death was a hideous shock 

to all her friends. She had been a freauent 

visitor at our home, and Fran~lin and f ware 

very fond of her. Franklin is e.11 associate 

physicist at ArEour Research Foundation in 

Chicago. 

Fred Kranz told us that he had a pleasant visit at your home last year. Fred is now 

m&.rried to a very dear friend of ours. Mo doubt 

you he~rd that Grace died suddenly about 5 years B.t.~O. If Franklin a.nd I ever get to iiashington 

we shall be glad to have a chat with you and 

Elizabeth. It was nice hearing from you. 1~y 

best wishes to yc,u and Elizabeth. 

Sincerely yours,

Not long ago I had occasion to try to locate certain 

papers of historical interest in connection with some of 

Riverbank's activities during World War I, and I wrote a 

letter addressed to Miss Cumming asking some questions 

about the possible disposition of the old records. I was 

then not aware or the unfortunate accident that caused Miss 

Cumming's death and received a reply from Miss T1nberg 

giving me that distressing news. But Miss Tinberg stated 

that everything had been turned over to the Library of Congress. · 

I he.ve been through the complete Fabyan collection at 

the Library of Congress and did not find anything of the 

sort of papers I'd like to have and then again wrote to Miss 

Tinberg asking her for your address in the hope that you ma.y 

be able to throw some light on what happened to the records 

of the work that we did for various departments in those 

days. Do you happen to know what Colonel Fabyan did with 

those records when the Cipher Department was closed? Were 

they all destroyed or did he happen to keep some locked up 

somewhere that now may be available? I would like very much to be able to refer to the old AT&T study as an interesting episode, for example, and some other things. I would 

very much appreciate a reply from you on this point. 

Don't you ever come to Washington? It vould be very nice to see you and your husband sometime and to relive some 

of the interesting days we spent together. All of us are 

well and I send you cordial greetings from Elizabeth and 

myself. 

Sincerely yours,
