Hector W. Kay was born in Australia, November 1, 1909. After his basic education in Australia, he completed his formal education in 1938 at Springfield College where he received a Masters Degree in Education. It was also here that Hector met and married Katherine Johnson, a Springfield native.  Hector’s early association with prosthetics and prosthetic education began at New York University where he spent the years 1952 through 1965 in the Adult and Child Prosthetic Studies group. During this period, he became intimately associated with the Sub-Committee on Children’s Prosthetic Problems of the Committee on Prosthetics Research and Development of the National Academy of Sciences/National Research Council. He was instrumental in developing the original cooperative clinic group, working very closely with the pioneers in this field: Drs. George T. Aitken, Charles Frantz, Newton McCollough and Claude Lambert. In 1965, he left New York University to join the Committee on Prosthetics Research and Development of the National Academy of Sciences/National Research Council as Assistant Executive Director. Here he continued to coordinate the activities of the Sub-Committee on Children’s Prosthetic Problems. The committee was gradually expanded to cover orthotic problems as well as the prosthetic problems. During this period, Hector also acted as editor of the Interclinic Information Bulletin. The Interclinic Information Bulletin has more recently had a name change to the Journal of the Association of Children’s Prosthetic-Orthotic Clinics. Hector retired from the Committee on Prosthetics Research and Development in 1974, and met a very untimely death on March 31, 1975. He is deeply mourned by all of those who knew him, respected him, and looked to him for advice. No organization owes more to one individual than does the Association of Children’s Prosthetic-Orthotic Clinics. Though founded after his death, ACPOC owes its existence to an organization he nurtured.
