Wilhelm Wundt
Wilhelm Maximilian Wundt (; ; 16 August 1832 – 31 August 1920) was a German physician, physiologist, philosopher, and professor, known today as one of the founding figures of modern psychology. Wundt, who noted psychology as a science apart from philosophy and biology, was the first person ever to call himself a psychologist. He is widely regarded as the "father of experimental psychology". In 1879, Wundt founded the first formal laboratory for psychological research at the University of Leipzig. This marked psychology as an independent field of study. By creating this laboratory he was able to establish psychology as a separate science from other disciplines. He also formed the first academic journal for psychological research, "Philosophische Studien" (from 1881 to 1902), set up to publish the Institute's research.
Applied psychology
The founder of applied psychology was Hugo Münsterberg. He came to America (Harvard) from Germany (Berlin, Laboratory of Stern), invited by William James, and, like many aspiring psychologists during the late 19th century, originally studied philosophy. Münsterberg had many interests in the field of psychology such as purposive psychology, social psychology and forensic psychology. In 1907 he wrote several magazine articles concerning legal aspects of testimony, confessions and courtroom procedures, which eventually developed into his book, "On the Witness Stand". The following year the Division of Applied Psychology was adjoined to the Harvard Psychological Laboratory. Within 9 years he had contributed eight books in English, applying psychology to education, industrial efficiency, business and teaching. Eventually Hugo Münsterberg and his contributions would define him as the creator of applied psychology. In 1920, the International Association of Applied Psychology (IAAP) was founded, as the first international scholarly society within the field of psychology.
