With so many incredible nursing theorists, it is impossible to resist discussing nursing’s first theorist-Florence Nightingale. Born in 1820, Florence became the founder of modern nursing. Her theories include the most well-known environmental theory. Some assumptions of her theory were: nursing is a calling, nursing requires a specific educational base, nursing is an art and a science, and natural laws just to name a few. Florence believed that the law of health was keeping the person and population healthy. What I admire the most about Florence is her strength in advocacy and her focus on leadership and education. Florence was quoted saying “Were there none who were discontented with what they have, the world would never reach anything better” (Nightingale, 2001-2012).
