Context

Country: Unknown
State/Province: Unknown
Period: This display probably assembled and subsequently used late1920s- 1930s.
Canada: Display presumably made by Dept. of Veterans Affairs, probably following WW1. Prior to 1973, this display was loaned to the museum at the Academy of Medicine by the D.A. via the Princess Margaret Hospital, Toronto. (Ref. 3)
Function: Unknown
Technical: Concentrated efforts made, particularly in Great Britain and North America, to develop practical, functional prostheses was largely driven by casualties of Great War. The sheer numbers of combatants and civilians requiring reconstructive surgery and the fitting of artificial limbs, including eyes, combined with advances in techniques and materials, taught medical practioners much and led to innovative designs and a better overall understanding of patients' needs. This display was probably fabricated during later 1920s- early 1930s. It incorporates some synthetic materials, including a cellulose nitrate based eyeglass frame, but the artificial eyes are made of glass. Synthetics began to be widely used for making of artificial eyes in 1940s. Ironically, prior to WWII, most glass artificial eyes were made in Germany, using methods not well known or understood in N. America. It was largely because of hostilities with Germany that research into the use of synthetics for the making of artificial eyes was accelerated. Glass artificial eyes must be blown in a flame, are extremely fragile, and when completed can not be polished or altered in any way. (Ref. 4)
Area Notes: Unknown
