1. Progress on Project l of Article I. Paragra~ a(l) of the oontract. 

a. The fifth of the series of six lectures required under the contract 

has been completed and the final typewritten manuscript. with minor corrections and insertions, has been turned over to the Office of Training Services. 

This lecture deals with the history of cryptology in the period from the end 

of the Civil War in the United States to the end of World War I. An earnest 

effort was made to condense this part of the hisi:iory in order to try to keep 

it within the bounds of what could be presented in a single lecture of 

approximately 50 minutes. However. it was found impossible to do so 'Without 

al together omitting a grea·I:; deal of interesting and useful information. In 

many cases only brief reference could be made to items of interest. and in 

some cases the only recourse was to refer to classified documents and 

brochures on file in the Office of Training Services or to books and other 

sources in the public domain for .further information. For example. in the 

case of the now ~~rld-famous Zimm.ernann Telegram. which some historians contend 

brought the United States into World War I as a belligerent on the side of 

the Allies and against the Central Powers. it was possible to make only a very 

brief reference to the circumstances surrounding the interception. solution 

and. most po.rticularly. the superb :manner in which the British Government 

exploited the re.markable achievement of its so-called 11Black Chamber11 

operated under Naval Intelligence (Room 40 O.B.). !rherefore. references were 

made to very detailed accounts and sources of information regarding this 

episode which probably changed the course of world history. The references 

included the contractor's presentation 1mich was recorded on magnetic tape 

and is on file in the Office of Training Services. a presentation 'Which held 

the attention of a special NBA audience for over two hours and which could

therefore hardly be included in toto in Leciiure No. 5. Nevertheless. despite 

all omissions and contractions of available material dealing with this era 

in cryptologic history. the manuscript of Lecture 5 is quite long and the 

recorded presentation will take at least tvro hours. Ho\vever. it should be 

relatively easy to break the printed and recorded presentation into sections 

of convenient length or duration. Furthermore. it is proper to mention that 

a great deal of information which had to be omitted froin.Lecture No. 5 is 

that which deals with cryptologic events and crytologic history pertaining 

specifically to foreign countries; the emphasis properly had to be placed 

upon information involving u. s. cryptologic history and this the contractor 

tried to do. 

b. The contractor will endeavor to produce a first draft of the final 

lecture (No. 6) as soon as possible and will forl"lard it for typihg to the 

Office of Training Services. 

2. Pro ress on Pro"ects 2, 3 and 4 of Article I, 

4 of the contract. 

a. The contractor has turned over to the Office of Training Services a 

nwnber of photographs, books and other material required for making the 

photographic negatives, photographic prints and lantern slides required for the 

presentation of Lecture No. 5 in print. or before an audience. (Projects 2 and 

3) 

b. The voice recording of Lecture No. 5 (Project 4) has been made and 

also has been turned over to the Office of Training Services.
