History of Health Care Computing

Since the beginning of time, people have invented tools to help them. Tracing the evolution of computers gives us a clearer historical vantage point from which to view our fast changing world. This approach also identifies informatics as a tool that will advance the goal of high quality nursing care. From a historical perspective, however, it is difficult to identify the true origin of computers. For instance, we could go back in time to the devices introduced by Moslem scientists and to the mathematicians of the fifteenth century. An example is Al-Kashi, who designed his plate of conjunctions to calculate the exact hour at which two planets would have the same longitude (de S. Price, 1959; Goldstine, 1972). A more familiar example is the first rudimentary calculating tool, the Chinese abacus. This is still a rapid and efficient method of handling addition and subtraction.
