She started the first formal nursing school.

Explanation:

Florence Nightingale is considered the founder of modern nursing. Her family considered nursing inappropriate for a good-looking lady, so she began her studies after age 31 on a training course in Germany. In England, Florence opened the first training course in 1860 and was considered the first formal school of nursing.

Florence did not know the concept of contact by microorganisms, as it had not yet been discovered, but she already believed in meticulous care about the cleanliness of the environment and personnel, fresh air and good lighting, adequate heat, good nutrition and rest, with maintaining patient vigor for healing.
