PURPOSE AND SCOPE
The purpose of this document is to nominate a unique and formidable body of work performed at the Cruft Laboratory for an IEEE Milestone. Cruft Laboratory is located on the campus of Harvard School of Engineering and Applied Science, Cambridge, Massachusetts. In general, this body of work belongs into two categories: the first is published academic research, experiments, inventions, and patents, in electronics and communications. The second category consists of special courses and training given to men and women of the armed forces in electronics and communications. This nomination addresses only the time period beginning in 1915 and ending in 1947.
This nomination covers just one of the building on campus during a specific time period. The accomplishments of many other electrical pioneers connected with the university, for example, John Trowbridge, Edwin H. Hall and AE Kennelly, cannot be taken into account here.
George Washington Pierce
GW Pierce was a radio pioneer and educator. He held a series of patents in wireless telegraphy, plus others in electronics. He was one of the first individual in the country to have a government-issued license to operate an experimental wireless station in New England. Others were John S Stone and Greenleaf Whittier Pickard. According to the 1913 edition of the Radio Stations of the United States, two of the five land stations in the Boston - Cambridge area were assigned the following call letters: 1YH to Harvard Radio and 1XP to George W Pierce. Pierce was an early inventor-scientist seeking to develop wireless apparatus for the US Navy. He and ‘Harvard Radio’ were in high regards by navy personnel at the Charlestown Navy Yard. Because of his credentials, Harvard received the first US government contract for scientific work. There would be many different government sponsored programs over the years, Radar for example, but as we shall see, the first was awarded for wireless work at Cruft Laboratory.
In 1929 Pierce was awarded the IRE Medal of Honor for his great work performed at the laboratory with this citation: “Major contributions in the theory and operation of crystal detectors, piezoelectric-crystals and magnetostriction frequency control and magnetostriction devices for the production of sound; and for his instructional leadership as a teacher and a writer of important texts in the electric wave fields.” His biography is given in the IEEE GHN http://www.ieeeghn.org/wiki/index.php/George_W._Pierce
Emory Leon Chaffee
Professor EL Chaffee’s principal work was in the realm of electric oscillation and electric waves, with special reference to vacuum tube phenomena. His name appears quite often in the Cruft Laboratory Annual Reports, some of which have been submitted with this proposal. He replaced Pierce as Director in 1940. In 1959, Chaffee was awarded the IRE Medal of Honor. The citation clearly refers to his accomplishments at the laboratory, for “his outstanding research contributions and his dedication to training for leadership in radio engineering.” Dr. Chaffee served as Vice-President of the IRE in 1922 and was a Fellow of the IRE as well as other organization. Chaffee’s biography is given in the IEEE GHN http://www.ieeeghn.org/wiki/index.php/E._Leon_Chaffee - Work_at_Harvard
Call for Wireless Operators
In June 1917, the Charlestown Navy Yard made an urgent appeal to recruit 2000 radio operators and telegraph operators. Applicants were expected to complete a three-months course of instruction at the Naval Radio School at Harvard University. The enrollment was for four years active service. Pay ranged from $33 a month up to $77 a month from the lowest rank up to chief electricians and radio operators. Age requirements were 18 to 35. Applicants for third-class had to copy 10 words per minute, continental Morse and be experienced with receiving and transmitting wireless apparatus. Applicants for second-class radio had to copy 20 words per minutes. Telegraphers for second-class had to copy 25 words per minute, American Morse. Applicants for first-class additionally had to copy 30 words per minute on a typewriter. Interested candidates were instructed to go to one of the recruiting office at Bar Harbor, Bath, Rockland, Portland, Provincetown, or the Navy Yards at Portsmouth or Charlestown.
The Naval School for Radio Operators at Harvard
On 17 June 1917, the Boston Globe wrote a very interesting article explaining what Harvard University and Harvard Radio were going to do to help with the war. Because of its historical content, the article has been transcribed. The headline begins “Harvard’s Naval School for Radio Electricians to Become Central Training Institution of Country.” Because of the poor quality of the images and copyright issues, they cannot be reproduced. The caption read: “Members of the school lined up for inspection. Prof George Washington Pierce, in charge of the Cruft Laboratory and Capt Rush of the Navy Yard, Center. Harvard Pres Lowell and Capt Rush on tour of inspection. Miss Mary Lamborghini, yeoman stationed at the laboratory.”
“The Naval School for Radio Electricians at Harvard, established early in April (1917), has been so successful that plans are now in contemplation to make it the central training institution of the country for radio operators of Uncle Sam’s fleet and shore stations.
“Already the school has graduated 32 of its students into first-class electrician rating and distributed them to posts aboard United States ships, including some of those which are now in foreign waters. At the present time there are 120 more men grinding through the intensive course of Naval training under directions of expert officers, and within three or four months they, too, will be ready for service wherever the Navy Department orders them.
“Should the present plan materialize, the personnel of the school will be expanded to include about 400 students. The room is there and the facilities are there. Pierce Hall, which has become the headquarters of the students, offers ample room for instruction and dormitory accommodations. The Cruft High Tension Laboratory, built in 1915 and operated under the supervision of Professor George Washington Pierce, is regarded by Naval officers as the best radio laboratory in the country, and in case of accident to the Chelsea Station it will be a valuable asset as a distributing station for this district, manned by experts in the service of Uncle Sam.
“These facilities, probably unequaled for an emergency of the kind presented by war, cost the Government nothing. Some weeks ago, after the declaration of war, Pres. Lowell offered the Government the free use of Pierce Hall and Cruft Laboratory. Soon afterward, the Naval School was established there under the direction of Lieutenant E.G. Blakeslee, communications superintendant of the 1st Naval District, and it’s first quota of students set to work. Chief Electrician H.D. Kent was placed in charge of half a dozen petty officers of the Navy as assistants.
“All of those who are accepted for training must be well grounded in the fundamentals of radio works. They must have a substantial knowledge of the construction of the machines, must have had some commercial experience or it’s equivalent, must be able to copy in the continental and so called radio codes, and must meet a certain sending standard. Many Harvard students who have had previous instruction in wireless operation are among the 120 now in the school. There are others from Cornell, Dartmouth, and M.I.T. and many of no college training; all are Uncle Sam’s Reservists. Aside from the opportunities offered, the value of the school rests in its strict discipline. Regular battleship routine is the fortune of those who have volunteered for the work. They are up at 5 am and spend the day at practical radio instruction, lectures, study of machines, paperwork and simple movements of the infantry drill, under strict Navy discipline. They take their meals with the student body at Memorial Hall.
“At 5 pm they find themselves with nothing to do until tomorrow. But tomorrow begins with the call to quarters at 8 pm and they are up at 5 am the next morning and at it again. Their present rating, that to which they are admitted upon preliminary examination and enrollment, is third-class electrician. Upon the completion of their course, which varies from three to four months, they qualify and rise a couple of notches in the petty officer rank to first-class electricians. From that time their fortunes are in Uncle Sam’s hands, that he may assign them to duty wherever he sees. It is one of the conditions of their enrollment. Many of them will go to the regular Navy ships, which will need plenty of their kind. Others will be assigned to boats of the ‘mosquito’ fleet or the coast patrol service, as more are put into commission. Still others will be sent to man new Government radio stations that are being established.
“The Cruft Laboratory was built about two years ago at a cost of some $50,000. It was a gift of Miss Harriet Cruft of Boston, in memory of her brothers, graduates of the college; Edward Cruft Jr., ’31, William Smith Cruft, ’31, Samuel R. Cruft, ’36, James Jackson, ’46. It was an innovation at the time, for prior to that radio courses had been confined to the Jefferson Laboratory.
“These courses have recently been transferred to Pierce Hall because of the proximity to the laboratory and its advantages as a barracks. Lectures are held at Pierce Hall and practical workings in the ‘lab’, which is provided with the most thorough equipment, including a new high-power arc. Many researches are conducted regularly by Professors Pierce and Dr. E.L. Chaffee, the experts in charge.
“The new school was inspected during the past week by Commandant W.R. Rush, Capt. Ashley H. Robertson, chief of staff, Lieut. Blakeslee, and others of the staff of the 1st Naval District and Command Rush was greatly pleased with the conduct of the institution.”
Additional description of the laboratory is given in this 1915 Annual Report.
THE NAVY TRAINING SCHOOL AND MORE
The first Radio Training School was established for the US Navy at Harvard ‘Radio’ in 1917. This was a landmark event because it was the first US government contract to establish a central institution for the systematic study of telegraphy, telephone and radiotelephony for navy personnel. Thousands of recruits were enrolled then graduated in short order.
Following the close of the college year of 1917, Harvard University offered the US Navy free use of campus buildings for classrooms, laboratories, and dormitories. This offer was gratefully accepted; the school was established and grew rapidly into a large institution. By the end of 1917, almost 5,000 students had enrolled in the 4-month intensive radio operating and indoctrination courses. Graduates went into service at a rate in excess of 100 a week. By early 1918, this had increased to 400 a week. Classes were held night and day throughout the war. To house the many navy and army recruits, some of the campus buildings had to be converted into dormitories. Portable trailers sprang up around the campus for supplemental housing. Space was always at a premium. Stockrooms and machine shops were in high demand for the many special projects taking place. During the war, a difficult problem was lack of space to accommodate both classes and scientific research. Things got worst after the war due to the growing field of electronics and the larger number of students pursuing work in that field. In one of his Annual Report, Pierce reported that “Cruft Laboratory was crowded before the war, but in the postwar period, space will be all the more urgent a problem.”
In addition to training of recruits, the armed forces were interested in research and development of secret signaling by radiotelegraphy. Many staff members were assigned to this type of research, such as, investigation and development of wireless remote controls for torpedoes. Pierce also participated in submarine sound detection systems for use in coastal defense and aid to navigation.
Pierce understood and appreciated the lessons learned during the war-training programs. He said that the teaching staff had opportunities to develop and improve teaching methods in electronics. In September 1920, he announced that the school would adopt a new program of studies in Electrical Communication Engineering. He planned this program to provide “for systematic study of telegraphy, telephony and radiotelegraphy, and for the training of persons for research and invention in this important branch of engineering.”
The academic and research activities pursued at the laboratory before the United States went to war, those activities carried out during the war, and those pursued after the war, are all well documented in the Cruft Laboratory Annual Reports. Only a few pages from these Annual Reports are included below.
RESEARCH, PATENTS AND PUBLISHED ARTICLES (1928-1929)
Accomplishments reported for the period 1928-1928 are given in the attached page of the Annual Report.
NAVAL TRAINING SCHOOL, PRE-RADAR COURSES, ARMY ELECTRONICS TRAINING CENTER (1941-1945)
In July 1941, members of Cruft Laboratory provided an exceptional national emergency response by acting rapidly to the call to provide training in electronics to 100 army officers. Within a short time the teaching staff was augmented by instructors from other institutions from across the country. This rapid response is documented: “25 new experiments were set up and 17 others planned and ordered. A new laboratory manual of 109 pages was written, edited, and published. Library, study, and laboratory facilities were expanded to meet the new demands.” By 6 July 1941, 100 Army officers had already registered for class. Courses in electronics and specialized subjects for officers in all branches of the military were given throughout the war to July 1945. The statistics on these courses and student enrollment are tabulated below:
Number of courses given 1 July 1941 to July 1945 = 57
Total students enrolled 6254
Total student hours 4,450,000
Total costs $966,886.21
Average cost per student $40.38
PROGRESS IN THE 1940s
Activities at the laboratory are well documented in the Annual Reports. Complete reports are accessible on line by exploring the Harvard Archive at this website http://library.harvard.edu/university-archives
Since accessing these archives may be difficult for some readers, copies of some of these pages are included here.
THE BOOK ELECTRONIC CIRCUITS AND TUBES (1947)
The simplest way to describe the courses delivered to the armed forces is to look at the book entitled “Electronic Circuits and Tubes” written by the Cruft teaching staff. McGraw-Hill published the book in 1947. It has nearly 1000 pages. The twelve members of the staff engaged in training army and naval officers wrote it. EL Chafee headed the team of experts - Harry E Clifford, Alexander H Wing, Harry R Mimmo, and others. Courses were designed for juniors and seniors attending colleges and engineering schools specializing in the study of communication engineering. The book was developed from the lecture notes of the special training courses given to graduate electrical engineers at Harvard. Chaffee explains how in the month of July 1941, courses were rapidly created, assembled and delivered to graduate electrical engineers enrolled as officers in the Signal Corps. Immediately after the declaration of war, the Navy also sent officers to what was called the ‘pre-radar’ courses. Since the preface and the forward of this book have useful historical information, they have been reproduced in the next paragraph.

BLOGGER YEOMAN RICHARD BRILL
It wasn’t all studies and no play. There was some occasional comic relief given by Yeoman Richard Brill’s newsletters. His address was the Army Electronics Training Office and Naval Training School. He had this to say: 27 August 1943 - Ever since the Radar Rockettes* made their debut, the Cruft Laboratory has not been the same. There was a time when one could enter the austere building and walk through quiet dignified halls. Now all is changed. An underground of swing is plainly discernable and one has the jivy feeling that a hepcat session is somewhere in progress though hidden from the electronic eyes of student and faculty.” * try googling Radio Rockettes.
19 November 1943 - Last Saturday, one of our more prominent Ensigns and one of our loveliest WAVES, after a four week whirlwind, high frequency courtship, completed a coupled circuit in a little church on Staten Island, New York. Up to this particular hook-up, the record for the Navy side of the Radar side of the Radar school has been eight weeks. Apparently, the accelerated courses given here at Cruft Laboratory seem to have had more than just a scholastic effect upon the students today.
