The patient health care was prominent even in the earliest stages of the development of human civilization, which can be testified by the sketches on the walls in caves and by its appearance in the ancient historical documents. It has been carried out since the earliest stages of human history until modern times. It has changed and developed by necessity through-out the time. In the beginning, the health care was performed by people of different occupations, who were either self-taught or skilled for it to a certain degree, and the health care existed only as a practical vocation. It was Florence Nightingale who began the professional development of nursing. Florence Nightingale (1820-1910) is considered to be a founder of professional nursing. She established the first nursing school in London in 1860 and wrote the first nursing course books she implemented in the nursing school: Patient Health Care, Child Health Care (for mothers), Child Health Care (for nurses), Hygiene of Work and Diet. Moreover, she gave the first definition of health care and defined the primary disciplines of health care. Also, she established the first nursing oath and created her own fund for education and nursing development in the world. To honour Florence Nightingale, the founder of the nursing profession, it has been decided to declare her birthday, May 12, an International Nurses Day and the International Red Cross Committee instituted the Florence Nightingale Medal, which represents the greatest award and acknowledgement for work in the field of nursing. Contemporary nursing entails, among other issues, the adequate education of the working staff and there has been an education harmonization currently in progress at the worldwide level, which stems from the foundations of the nursing profession established by no other but Florence Nightingale by all means.
