John Broadus Watson (1878 - 1958)
John B. Watson was educated at Furman University and the University of Chicago, where he later taught from 1903 to 1908. From 1908 to 1920, he was professor of experimental and comparative psychology and director of the psychological laboratory at John Hopkins University. In 1920, he entered the advertising field. He eventually became a vice president of the J. Walter Thompson Company, New York City, in 1924. He was vice president of William Esty & Company from 1936 until 1946. Watson was one of the first and most influential proponents of behaviorism, which dominated the psychological community of the United States in the 1920s. By the late 1940s its influence had declined, but its impact upon the field of psychology is still clearly evident.
