Q: Passage: Campbell began her career as a dietitian at the Baptist College in Brandon, Manitoba. Immigrating to the United States in 1909, she took employment in South Bend, Indiana at the Epworth Hospital as a dietitian and instructor in domestic science and remained until 1911. She returned from Canada in 1914 and entered the Pasadena Hospital Training School for Nurses. In 1917, she graduated having earned her RN designation. The following year, she joined the Nurse Reserves of the United States Army Nurse Corps and began working as a staff nurse at the base hospital of Camp Fremont in Palo Alto, California. After serving at Letterman General Hospital, in San Francisco, she was sent to Fort Leavenworth, Kansas in 1920, to take up a post at the hospital for the United States Disciplinary Barracks. With this move, she became an American citizen and was transferred as a second lieutenant to the Regular Army of the Nurse Corps. Between 1921 and 1922, she was deployed to Coblenz, Germany, serving with the Allied Occupation Forces assisting with Russian famine refugees, influenza victims and war casualties. Returning to the United States, in 1924, she was promoted to first lieutenant after passing the Chief Nursing Examination.
