The paradigm constitutes the development of what is called "normal science". On the other hand, one of the essential characteristics of medical and nursing practices in primary health care (PHC) is the longitudinal heed of human beings. William Rathbone VI was a merchant and businessman noted for his philanthropic work. In 1859 his appreciation for the services of a nurse, Mary Robinson, engaged to care for his dying wife, prompted him to campaign for a system of district nursing to enable the poor to benefit from similar care. Florence Nightingale advised him to establish a training home in Liverpool, which was completed by 1863. Regardless of who it may be, the longitudinal paradigm in today's primary care is of nursing and not medical source. The role of religious orders has been different from a historical point of view and it jumps the temporal limits of Late Modern Period of History.
