The first young Roosevelt to serve was Ethel Roosevelt Derby (1891-1977), who had trained as a nurse. She married Dr. Richard Derby, a surgeon, in 1913. In 1915 both of the Derbys went to France as a part of the Red Cross Mission of Mercy. Both were assigned to the American Ambulance Hospital in Paris, where they remained until 1917, when they returned to the U.S. because Ethel was pregnant. Although her nursing career was over, Ethel was very active with the Red Cross, eventually earning a sixty year service pin.
