A requirement that large military equipment be X-rayed led the University and several local companies to build a million volt X-ray machine that opened in January 1943 in a new building on the north side of Elmwood Avenue, next to the University's Central Utilities Plant. Dr. Stafford L. Warren, professor of radiology, headed up that project and in February 1943 he was recruited by General Leslie R. Groves to join the secret Manhattan Project that was developing atomic weapons.. An addition to the X-ray building (known as the 'B' section) was opened in September 1943 and another structure ('C') was added in early 1944. A third floor was added to the south wing during the 1950s..
The Manhattan Project was transferred to the new Atomic Energy Commission on January 1, 1947 and continued its work at the University, building a Cyclotron on River Campus in 1947 and the O Wing in 1950, which included a new tunnel under Elmwood Avenue to connect that building to the east end of the Annex building.
The buildings were later cleaned of radiation and transferred to the University, where now house laboratory and office space.

The west wing of the present Medical School Annex on the north side of Elmwood Avenue had already been completed in January, 1943. It ·was built to house million-volt x-ray equipment supplied by several Rochester industries in order that they might have a facility to x-ray gun mounts and other military supplies to ensure conformance with the government's specifications. It was decided to erect the new Manhattan laboratory contiguous to this building. Construction was begun early in June and completed on September 1, 1943. This addition of the two-story red brick south and east wings along with the one-story concrete-block structure completed the "Annex" as it stands at present.

Page 10: As mentioned above, the building occupied by the Department on the north side of Elmwood Avenue is called the Medical School Annex, or just the Annex. It now consists of three wings, A, B, and C. Wing A, 9700 sq. ft., was constructed in 1942 by the University to house high voltage X-ray equipment for testing castings for the Armed Forces as previously mentioned. Wing B, originally 15,000 sq. ft., and Wing C, originally 19,000 sq. ft., were built by the Manhattan District in 1943 and 1944. Education space, O Wing, 53,000 sq. ft., was built by the Commission as an addition to the Medical School in 1950. A tunnel under Elmwood Avenue connects this building to the Annex. Additions to B Wing of the Annex have been: the Alpha Laboratory , 6,000 sq. ft., in 1952; a third floor, 5,200 sq. ft., in 1961; and a low level counting facility, 600 sq. ft., in 1964. In 1951 900 sq. ft. were added to C Wing for flash burn studies. A radioactive storage vault, 200 sq. ft., was constructed off the tunnel joining the Annex and the Medical School in 1961. All of these additions were built by the Atomic Energy Commission. During 1965 and 1966 additions to O Wing of the Medical School totaling 50,000 sq. ft. were constructed. These consisted of an underground radiation facility off the tunnel and an eight-story building, OO Wing, adjoining O Wing and containing laboratories and lecture rooms

Page 280: Rochester first became involved in this medical program in the middle of February 1943 when Dr. Albert K. Chapman, then vice president and general manager of Eastman Kodak Co., invited Dr. Stafford L. Warren, then professor of radiology at the Medical School, to luncheon at the Rochester Club. At the luncheon Dr. Warren was introduced to General Groves and Colonel Marshall, who queried him on his experience with radiation and radioactive materials.
Following the luncheon, Dr. Chapman left, after advising Dr. Warren to do whatever the officers requested. Then, according to Dr. Warren's account, the officers took him to a private room where, after locking the door, closing the transom, and examining a closet, they asked him if he would consider working on a medical program of great importance to the government but which involved the utmost secrecy.
Following consultation with President Valentine and Dean Whipple, on March 2, 1943 Dr. Warren accepted an appointment as civilian consultant to the Manhattan District.
In April 1943 Dr. Warren and Major H. L. Friedell of the Manhattan District planned an initial research program at Rochester.
On June 2, 1943, the present B Wing of what is now called the Annex was started on the north side of Elmwood Avenue and was rushed to completion by September 1943. This building, along with the adjoining, preexisting A Wing of the Annex, which had been built the previous year by the Radiology Department and equipped with a million-volt x-ray machine to examine castings for the armed forces, provided a center for the new program. Additional space was provided by other departments, notably biology, physics, biochemistry, and radiology.

Chapter 31: Women, Music and Medicine in Wartime
Easily the most exciting chapter--and the most closely guarded secret--in the history of the School of Medicine involved the participation of staff members in the so-called Manhattan Project that produced the first atomic bombs. Back in 1939, American scientists had started researches pointed toward the making of an atomic bomb; but progress was slow until taken in hand by the National Defense Research Committee, known subsequently as the Office of Scientific Research and Development of the War Department (OSRD).
At mid-February of 1943, Dr. Albert K. Chapman, at the time vice-president and general manager of the Eastman Kodak Company, invited Stafford L. Warren; professor of radiology at the Medical School, to lunch where he met Major-General Leslie R. Groves, chief officer of the Manhattan District, U.S. Army Corps of Engineers. After Warren had been thoroughly grilled on his experience with radiation and radioactive materials, he was taken into a tightly-sealed room and asked whether he would undertake an extremely important medical assignment requiring the utmost secrecy. He consented. Groves next waited upon President Valentine and requested the services of Warren for work very vaguely outlined. Valentine reluctantly agreed to a leave of absence, reluctantly inasmuch as so many high-ranking University scientists had already been "kidnapped" by the government; and he pledged every possible University support for the enterprise. On March 2, 1943, Warren was named civilian consultant to the Manhattan District.
Warren was chosen primarily because he and Whipple had carried out important pioneer investigations on the injurious effects of X-rays upon dogs; succinctly stated, Warren was called upon to administer a laboratory in which to study health hazards for workers engaged in atomic research. Temporarily, space for research purposes was allocated in several sections of the Medical Center, while essential facilities were being constructed to the north of Elmwood Avenue. Called the Medical School Annex, the structure consisted of three wings, one already in use for high-voltage X-ray equipment, and ground for the other two units was broken on June 2, 1943. At the outset seven men comprised the research team, within three months fifty were on the job, and seven times more by the time atomic bombs were unloosed over Hiroshima and Nagasaki.
Experts from the Eastman Kodak Company and other Rochester firms took part in the investigations, which required a wide diversity of training and professional experience and a skillful coordination of a variety of scientific techniques. When in November, 1943, Warren was summoned to become medical director of the entire Manhattan Project with headquarters at Oak Ridge, Tennessee, his first lieutenant, Andrew H. Dowdy, was put in charge of the program at Rochester; major colleagues were William Bale, in apparatus and instrumentation, Harold C. Hodge in toxicology, Joe W. Howland in medical sciences, and Henry A. Blair in the biological effects of radiation.
Among the problems posed to the University investigators were physical examinations of personnel in nuclear energy plants exposed to occupational hazards, methods of safeguarding workers engaged in atomic energy production, such as the toxicity of radioactive materials, the biological consequences of direct exposure to radiation, and the genetic effects of ionizing radiation. For experiments about half a million mice were used, some 200 monkeys, and other animals; consternation reigned (1944) after a monkey escaped and indulged in monkeyshines for a fortnight until captured at a football game, in readiness presumably to cheer for the University eleven.
Tight security regulations prevailed. Guards refused admission to the Annex to anyone without an official pass, workers engaged in a given piece of research were prohibited from discussing it with others, and the findings of the medical scientists were disclosed to only a few high-placed individuals. After Japan capitulated, a modification in the "enforced secrecy" permitted the University to reveal part of the part it had played in the atomic bomb project, and high praise from Washington accrued to the University for what had been accomplished. Thanks to the Rochester scientists, not a single employee of the thousands involved in making the A-bomb suffered injury by radiation or kindred phenomena. 17
Installed in the midst of the war, a powerful million volt X-ray machine, mentioned above, was used for therapy and research and to test materials for the military--heavy armor, aircraft parts, high pressure marine valves, and so forth. Rochester firms paid for the building and equipment, and in a single year thirty-five companies had recourse to the facility; in fact, the demand grew so large that a second machine was set up.
