Regarded as the father of psychoanalysis, Sigmund Freud was a neurologist. Despite suffering criticism, psychoanalysis remains influential in the fields of psychology and psychiatry; such is the influence Freud has on humanities. Scholars believe that Freud is one of the most influential personalities of the 20th century and that his impact is comparable to that of Marxism and Darwinism.
