Abraham Maslow, born in 1908, was an American psychologist who played a fundamental role in the history of psychology. He pioneered a new way of understanding this science, focusing not only on mental disorders, but also giving importance to human potential. His theories focused on the positive aspects of human nature, so he conducted his research on studying mentally healthy people. His paradigm led to the development of the humanistic approach to psychology, and his most famous and popular contribution is his hierarchy of needs. Maslow based his theories on the belief that individuals are born with the desire of achieving their maximum potential, or reaching what he described as self-actualization, through the satisfaction of a variety of needs.

Maslow's perspective and ways of understanding psychology inspired many other researchers. Nowadays he is remembered as one of the most influential psychologists of the 20th century.
