Who were Gelfan and Bell?

Divinyl Ether was first administered to man by Dr. Samuel Gelfan and Dr. Irving R. Bell in
the old Medical Building on the University of Alberta campus in 1932. Drs. Gelfan and Bell
deserve considerable credit for taking that very important first step to evaluate the use of
DVE in humans.

More information can be found in this excellent article: Canadian contributions to the
introduction and use of divinyl ether by Brendan T. Finucane Department of Anesthesiology Emeritus.
