The Beginnings of Modern Psychology
Some argue that modern psychology emerged in the 18th century, owing largely to William Battie's "Treatise on Madness," which was published in 1758. Others consider the mid-nineteenth-century experiments in Hermann von Helmholtz's lab to be the birthplace of modern psychology.
Others argue that modern psychology began in 1879, when Wilhelm Wundt, dubbed the "Father of Modern Psychology," established the first experimental psychology lab. Psychology would evolve from that point forward, as it still does today.
