While establishing a sanatorium and confirming the value of his innovative use of crafts as a medical tool, Dr. Herbert J. Hall gave lectures and published many articles and books to proclaim his discoveries. Others were experimenting with occupational therapy practices in different forms within mental institutions. Their views and perspectives differed from Hall's practice, the main issues being the market value of crafts and their use as a diversion. This article also includes Hall's psychological principles of indirection, equivalents, immunity, and substitution, and the graded process as observed and applied to the disabled.
