Name:
Named in honor of Gabrielle/Gaibrielle "Gai" Donnay (née Hamburger) (1920, Landeshut, Silesi, Germany (now Poland) - 4 April 1987, Mont St. Hilaire, Quebec, Canada), chemist, mineralogist and crystallographer. She worked for twenty years at the Geophysical Laboratory, Carnegie Institution of Washington and later at McGill University, Montreal, Canada. For her Ph.D. thesis she solved the complex structure of tourmaline, and later solved numerous other structures. The mineral donnayite-(Y) is also named for her, as well as her husband.
