Nursing students&apos; access to higher education does not mark the beginning of basic scientific research into this discipline, and it is now a struggle for this fact to remain visible.&lt;p&gt; Prejudices, misrepresentations and myths mislead nurses about the origins of nursing knowledge. Discipline of Nursing allows us to compare significant nursing figures: Florence Nightingale (Great Britain) and her equally valuable counterpart Valérie de Gasparin-Boissier (Switzerland). The two distinct training models proposed by these illustrious women have retained their relevance into the 21st Century since as early as 1859. &lt;p&gt;The discipline of nursing seems to be arranged in almost geological layers of knowledge that we can distinguish by studying the traditions of nursing language. This book aims to provide a better understanding of the nature of services provided by nurses worldwide.
