William James was born in 1842 in New York City to a wealthy family. He studied physiology, chemistry, and attended medical school but struggled with deciding on a career path due to ongoing back pain. After becoming depressed due to this indecision, he found new purpose in psychology. James went on to make major contributions to the fields, including establishing pragmatism and functionalism as philosophical approaches and proposing the James-Lange theory of emotion. He is regarded as the father of American psychology.
