In 1900, St. Paul Sanitarium opened Dallas' first "Training School for Nurses." The first three nurses graduated in 1903 and are posed in the front row, with the nursing students behind them. The black ribbons on the graduates' hats indicate they have received their degrees. The name of the school later changed to "St. Paul School of Nursing." It operated until 1971, when it closed due to the shift of nursing education to four-year colleges.
