This series contains a large proportion of correspondence, but also interoffice memorandums, publications apparently filed for reference, professional papers, circulars, committee records, functional tests, muscle and other test schedules, records of professional symposiums, annual, monthly and miscellaneous reports, staff schedules, reprints of various articles authored by Dr. Bennett, requests for treatment, residencies, speaking engagements, etc., a biographical sketch, other personal files and other records documenting the activities of the Warm Springs Foundation in its latter years. Apparently Dr. Robert Bennett assumed a supervisory capacity at the Warm Springs Hospital at about the time that Dr. C. E. Irwin left the facility. It is interesting to note the apparent growth of the hospital during Dr. Bennett's tenure as senior officer. Not only did the volume of records generated increase significantly, but Dr. Bennett also had to resort to closer administrative control over the various divisions of the facility. This fact is exemplified in the large number of interoffice memorandums in this series which are not present in Dr. Irwin's files (see Series 21). Many of the subject headings in both series, however, are identical.
