Jlarch 20 J 19$2 

I was very happy to hear of your graduation f'roa the Johns Hopkins · Medical School and I am sure that your internship there will be most - successful. 

In answer to your inquiry concerning an &!glish translation at the 

1947 edition of Sacco•s Manuele di Crittografi.a, I am sor:ry' to say that, 

so far as I know', no Eng1ISb t:ranSlit!on his Been published. A draft 

translation of this volume vhich ..ras made here requires much revision 

before it can be issued. 

I can reter you, however, to a French translation of this book which 

was recen~ published• the bibliographical intc:rma tion on which is 

given bel.ow: 

~anuel de Cryptographie, General L. Sacco. Qliti.on trancaise 

par le Capitaine J. Bree d• apres la troisiame edition 

italienne revue par l•auteur. Preface by Lt. Colonel R. Leger. 

PuJ:>lisbed by Pqot, Paris 106,, Boulevard Sa1nt-Gemain,, 19Sl.. 

I am. sure that, it you write to the Firm Pay-ot, 70u will be able to obtain 

a copt of this translation. The price, if I reaamber correctly, is not 

great, approximately $3.SO. You vill undoub~ .fim the French versicm.,, 

which may be pr_esumed to be relatively accurate sinee it ms reviewed. b,r 

Sacco,. easier to read than the Italian. 

With all good wishes £or your continued success,. I am.

" Mr. William. F. Friedman 

424 North George Mason Drive 

Arlington, Virginia 

Dear Mr. Friedman: 

I surely enjoyed my correspondence with 

you while I was o~ duty at -Carlisle Barracks 

in the swnm.er-~~- 1950. Since that time I have - been graduated from medical school here and 

E:an an internship in eye disorders last July. still in the Army Reserve but have been ransf erred to the Honorary Reserve due to 

marked myopia. 

~Y interest in cryptography continues, 

however, and I am wondering if you might be 

good enough to advise me as to whether there ls 

now an English translation of the 1947 edition 

of Sacco' s MANUALE DI CRITTOGRAFIA. I en .1 oyed reading the translation of the older edition, 

and I have a copy of r.ny own of the 1947 edition. 

My Italian 1 s poor, however, and in the. sections 

on mechanical devices, in which I am pa~ticular- 1 ly interested, I have been able to read .. fairly well only the portions on already familiar 

devices. If a translation is available, I 

should very much appreciate the short use of a 

copy. An FBI check was carried out on me in 

1951, so I asswne that I can make use of 

RESTRICTED material at least. 

I should be very thankful for any help you 

may be able to give me on this matter. I'm 

looking forward to the sixth or seventh volume 

of Jefferson's Writings for your section. 

Best ·w1shes to you. I surely appreciate 

your previous kindness in answering my questions. 

Very sine ely you s,J/ d·

Eeceipt of your very nice letter of 27 Jun~·19s0 la acknowledged. 

It was good to hear from TOU. · 

The interlinear addition near the bottom ot the first page ot 

the Jefferson mar.uscript reads: 116. vowels & 4. liquids." I presume 

you know that in the science of _pho~etics c~rtain conaonants ~r the 

alphabet, such as z and J:, are c~lled liguids. 

It you are interested in f i~tiing contemporar.r ref ererices to 

Jefferson's invention· or.use of the. device1 7ou will be aa diaappoi~ted 

as I was.. So far, I have not been able to find .&li}'thing more than the 

£act that Jef'f eraon described the device a second ti.me, w~icb· is also 

among his manuscripts. The second description is merely' a smootb 

copy ot the ti~at -- tho two are pract!cal.l,v identical. However, I must 

adu that I have n~t made any speciric search,1n contemporar;y_reco!'ds 

or literature and don't kl'low what su_ch .. a search .m15ht :unc9ver. · 

The Editor-in-Chief of the Definitive Edition. of Jeffersonis 

lritings, a project being conducted at Princeton,· asked me to ~ite 

a com~entary on Jetrerso~'• invantion, .in abou~ SOO words •. However, 

the story was so interesting that I felt it.desirable to go b91ond that 

limitation. I ••nt him a co~~entary runnin3 to ~ couple or thousand 

words, ~nd app~ront}J' it pleased him so much that he accepted it in 

toto. It will appear in the sixth or seventh volume, which 1s to be 

published in 4 or 5 years from· now. ::ow~ver, in the first volume, which 

waa published quite recen~ly, there appears in the introduction a foot- ·· note making reference to Jefferson's invan~ion or the Cypher·v~'heel. I · have not soen the footnote in print·<hough I did so over it before it 

was 1~corporated' i:i Volume l. · ··
