A、Public hygiene in the United States. B、Florence Nightingale: a nurse’s story. C、The fight for nursing education in the United

Before the 1870’s, trained nurse were virtually unknown in the United States. Hospital nursing was an unskilled occupation, taken up by women of the lower classes, some of whom were from the charity house. The movement for reform originated not with doctors, but among upper-class women, who had taken on the role of guardians of a new hygienic order. Though some doctors approved of the women’s desire to establish a nurses’ training school, which would attract the daughters of the middle class, other medical men were opposed. Plainly threatened by the prospect, they objected that educated nurses would not do as they were told. When resisted, as they were at Bellevue in efforts to install trained nurses on the maternity wards, they went over the heads of the doctors to men of their own class of greater power and authority. Professional nursing, in short, emerged neither from medical discoveries nor from a program of hospital reform initiated by physicians; outsiders saw the need first.
