Notwithstanding the conviction of certain lending civilian scientists that space medicine was an entirely new field, the U.S. Air Force bioastronautics community as early as 1949 had considered space medicine to be an extension of aviation medicine.3
Indeed, as early as World War I, the Army—parent of the U.S. Air Force-had trained a special kind of medical officer, the flight surgeon. This specialist, while still serving in many cases as a clinician treating sick patients, more often functioned as a medical officer concerned with healthy pilots under the unique stress of surviving in an al en atmosphere. He also worked with the design engineer on the development of equipment and instruments to help a pilot overcome the adverse environment. Thus, medicine was already wedded to flight technology. This had led to manned flight at extreme altitudes by midcentury. Ultimately, the bioastronautics experts believed, it would lead to manned space flight.
The U.S. Air Force (a part of the Army until 1947) had thus recognized as early as World War I that the physician was vitally important as a member of the aeronautics team.4 During World War I the new School of Aviation Medicine (SAM) at Mineola, Long Island, had concerned itself with the physiological problems of stress faced by man in flight, and the medical staff had concentrated on establishing physical standards necessary for military pilots. Following World War I the school had moved to Brooks Air Force Base, Tex., and subsequently to Randolph Air Force Base, where a small in-house group sponsored aviation medical research and education, the only resource of its kind in the world.5
After World War II the commandant, Col. Harry G. Armstrong6 , a pioneer in aviation medicine, gathered together certain leading German scientists in the field of aviation medicine and space science.7 On February 9, 1949, the first Department of Space Medicine in the world was established at the school, and Dr. Hubertus Strughold subsequently became the first professor of Space Medicine.8
As director of aeromedical research for the German Air Force, Dr. Strughold had been aware of the space-flight ambitions of Drs. Walter Dornberger and Wernher von Braun of the V-2 program at Peenemunde. He had himself theorized for several decades on the medical implications of space flight.9
Strughold and his modest SAM staff in 1949 estimated that the main medical problems of space flight could be formulated and the majority of the questions fully answered within 10 to 15 years. Hardware could be developed within 15 to 20 years. The first manned space flights thus would become feasible between 1964 and 1969.
Among the fundamental studies initiated were those in acceleration,
noise and vibration, atmospheric control, weightlessness. and nutrition.
Unfortunately, noted one British lecturer:
As a first step toward solving these problems, the School of Aviation Medicine turned to the experience of the Germans at Peenemunde and in the German aeromedical laboratories. This led to the publication in 1950 of the two-volume German Aviation Medicine in World War II, prepared by 56 leading German aviation specialists, and translated and published by the U.S. Air Force. Such topics as the physiological fundamentals of high altitude and acceleration and the potential problems of man under gravity-free conditions were discussed.11 Thus the advances of German aviation medicine in World War II became spoils of war and a part of the open literature in the field.
Meanwhile, as early as 1948, representatives of the U.S. Air Force School Of Aviation Medicine and the Lovelace Foundation had held symposia aimed toward aiding the accomplishment of manned travel in the upper atmosphere, emphasis being on the concept that "one must learn to walk before one runs." Two subsequent symposia in 1950 and 1951 led to the publication of Physics and Medicine of the Upper Atmosphere, which provided data cross sectioning of four scientific disciplines: Astrophysics, aeronautical engineering, radiobiology, and aviation medicine.12 The need for cross-fertilization of scientific disciplines, as recognized by this group of the Nation's scientists, was the most important single factor with which the scientific community during the next few years must cope to meet the complex requirements of the advancing technology of manned flight and manned space flight.
By the midfifties current thinking in the Air Force was increasingly
oriented toward possible manned space flight. For example, in February
1957 The Journal of Aviation Medicine published an article on "Selection
and Training of Personnel for Space Flight," which concluded that "space
flight is not drastically different from most aspects of aviation which
are now familiar."13
This article aptly foreshadowed the pattern that was actually followed
in the selection and training program for Project Mercury.

The group was joined subsequently by Dr. Hans Georg Clamann, who became research physiologist at the school, and by Dr. Siegfried Gerathewohl, who had been chief of the Psychological Testing Center of the German Air Force during World War II. Gerathewohl later joined NASA.
