These two microscope slides probably represent the earliest artifacts that relate to space medical research. They comprise thin sections of brain and lung tissue taken from mice subjected to 212g's in a centrifuge in the laboratory of Professeor Milian in Paris in 1932. The slides show considerable tissue damage from the high acceleration forces. These experiments were a follow-on of a series started in 1931 by Wernher von Braun when he was a student at the ETH in Zurich.
The slides were donated to the Smithsonian Institution in October 1968 by Constantine D.J. Generales Jr., MD, D.Phil.
