The Florence Nightingale effect is a trope where a caregiver develops romantic feelings, sexual feelings, or both for their patient, even if very little communication or contact takes place outside of basic care. Feelings may fade once the patient is no longer in need of care.
Origin
The Nightingale Effect - meet my new band playing some song's for you.
The effect is named for Florence Nightingale, a pioneer in the field of nursing in the second half of the 19th century. Due to her dedication to patient care, she was dubbed "The Lady with the Lamp" because of her habit of making rounds at night, previously not done. Her care would forever change the way hospitals treated patients. Most consider Nightingale the founder of modern nursing. There is no record of Florence Nightingale having ever fallen in love with one of her patients. In fact, despite multiple suitors, she never married for fear it might interfere with her calling for nursing. Albert Finney referred to the effect as the "Florence Nightingale syndrome" in a 1982 interview, and that phrase was used earlier to refer to health workers pursuing non-tangible rewards in their careers.
