FLORENCE NIGHTINGALE

Florence Nightingale (1820-1910), considered the founder of educated and scientific nursing and widely known as "The Lady with the Lamp"[1], wrote the first nursing notes that became the basis of nursing practice and research. The notes, entitled Notes on Nursing: What it is, What is not (1860), listed some of her theories that have served as foundations of nursing practice in various settings, including the succeeding conceptual frameworks and theories in the field of nursing.[2] Nightingale is considered the first nursing theorist. One of her theories was the Environmental Theory, which incorporated the restoration of the usual health status of the nurse's clients into the delivery of health care—it is still practiced today.
