American Occupational Therapy Association (AOTA), was founded in 1917 and the profession of Occupational Therapy was officially named in 1921. William Rush Dunton, one of the founders of NSPOT and visionary figure in the first decades of the profession struggled with "the cumbersomeness of the term occupational therapy", as it lacked the "exactness of meaning which is possessed by scientific terms". Other titles such as "work-cure", "ergo therapy" (ergo being the Greek root for "work"), and "creative occupations" were discussed as substitutes, but ultimately, none possessed the broad meaning that the practice of occupational therapy demanded in order to capture the many forms of treatment that existed from the beginning. The emergence of occupational therapy challenged the views of mainstream scientific medicine. Instead of focusing purely on the medical model, occupational therapists argued that a complex combination of social, economic, and biological reasons cause dysfunction. Principles and techniques were borrowed from many disciplines—including but not limited to physical therapy, nursing, psychiatry, rehabilitation, self-help, orthopedics, and social work—to enrich the profession's scope. Between 1900 and 1930, the founders defined the realm of practice and developed supporting theories. By the early 1930s, AOTA had established educational guidelines and accreditation procedures. The early twentieth century was a time in which the rising incidence of disability related to industrial accidents, tuberculosis, World War I, and mental illness brought about an increasing social awareness of the issues involved. The entry of the United States into World War I was also a crucial event in the history of the profession. Up until this time, occupational therapy had been concerned primarily with the treatment of people with mental illness. However, U.S. involvement in the Great War and the escalating numbers of injured and disabled soldiers presented a daunting challenge to those in command. The military enlisted the assistance of NSPOT to recruit and train over 1,200 "reconstruction aides" to help with the rehabilitation of those wounded in the war. With entry into World War II and the ensuing skyrocketing demand for occupational therapists to treat those injured in the war, the field of occupational therapy underwent dramatic growth and change. Occupational therapists needed to be skilled not only in the use of constructive activities such as crafts, but also increasingly in the use of activities of daily living. There was a struggle to keep people in the profession during the post-war years. Emphasis shifted from the altruistic
