In Rome, in the third century, there was an organization of men called the Parabolani brotherhood that provided care to the sick and dying during the great plague in Alexandria. During the crusades, groups of men known as Knighthood orders, such as the Knights Hospitalers of St.John of Jerusalem, the Teutonic Knights, and the Knights of Larzarus, comprised of brothers in arms who provided nursing care to their sick and injured comrades. These orders were responsible for building, organizing and managing great hospitals, setting a standard for the administration of hospitals (predominantly in the battlefield) in Europe at the time.
Another male group, the Alexian Brotherhood, was organized in 1431. Knighthood orders of the Middle Ages combined religion, chivalry, militarism, and charity. Their original purpose was to carry the wounded from the battlefield and to provide care.
Seventy years before the pilgrims landed on Plymouth Rock, Fray (Faiar) Juan de Mena was shipwrecked off the south Texas Coast. He is the first identified nurse in what was to become the United States.
In the middle 1800s the United States was embroiled in the Civil War. Both the Confederate and Union Army had males serving as nurses although we only hear about the Union volunteers, who were predominately female. The Confederate Army had assigned thirty men in each regiment to care for the wounded. This could have been the start to the modern Combat Medic of today. The Union also had males designated as nurses or serving as such. See Walt Whitman below. In the year 1808, Lazaro Orranti and Martin Ortega were two men that were employed as nurses at a hospital in San Antonio. The hospital employed only men as nurse. A Century later a sign above the door to the San Antonio hospital nurse quarters said Entrance to No Mans Land.
At the turn of the century, female nurses started to organize. In 1894, the superintendents of Female Nursing Schools (who were all female) gathered in New York for their first annual meeting. The Nurses Associated Alumnae of the United States and Canada had their first annual meeting in 1898. The delegates to the 1900 convention were reported to have only one married women and no men. The Nurses Associated Alumnae became the American Nurses Association (ANA) in 1917, and Men were excluded until 1930.
One of the early accomplishments of the female nursing organizations was to exclude men from nursing in the military. In 1901 the United States Army Nurse Corp was formed and only women could serve as nurses. At this point in history military nursing which had been mostly males changed to being exclusively female.
It would be a long time before males were again allowed to be nurses in the military. It was not till after the Korean War that men were permitted back into nursing. During the intervening decades men who were Registered Nurses enlisted and were drafted, but they were not assigned as nurses.
Once males were again permitted into military nursing, the numbers with in the civilian population also started to increase. The chances of having an all male team of nurses is more than five times as likely to occur in the Military than in the civilian healthcare world. One of the little known facts of military nursing is the high percentage of men in all three services. In the Army 35.5% of its 3,381 nurses are men; in the Air Force, 30% of 3,790 nurses are men; and in the Navy, 36% of the 3,125 nurses are men. One must remember that in the nursing profession that only 6% is male. In the Army, 67% of CRNAs are men, 40% of the OR nurses are men, 34% of ED nurses are men, 29% of critical care nurses are men and 39% of medical/surgical nurses are men.
