This series contains the correspondence of a professional nature of Dr. Michael Hoke who was employed by the Foundation during the early 1930's as an assistant to the then Chief Surgeon, Dr. C.E. Irwin. Since the vast majority of these records dates from the year 1935 and since most of the letters were exchanged with individuals with surnames beginning with the last letters of the alphabet, it may be assumed that Dr. Hoke's responsibilities at the Foundation gradually increased over the years and that he may have been specifically assigned that portion of the alphabet for the surgical section.
