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.
Kenneth Spence
Kenneth Wartinbee Spence (May 6, 1907 – January 12, 1967) was a prominent American psychologist known for both his theoretical and experimental contributions to learning theory and motivation. As one of the leading theorists of his time, Spence was the most cited psychologist in the 14 most influential psychology journals in the last six years of his life (1962 – 1967). A "Review of General Psychology" survey, published in 2002, ranked Spence as the 62nd most cited psychologist of the 20th century.
