Jacques Bardet

Jacques Bardet, a French inorganic chemist, was born in France in 1885 and married Juliette Voirin. His PhD Dissertation at the Sorbonne in Paris (1914) was entitled "Recherches spectrographiques et analytiques sur les eaux minėrales francaises." He also wrote "Separation of Celtium [hafnium] and its arc spectrum" (1925), and "Atlas des spectres d'arc" (1926). Bardet discovered that after thermal and chemical treatment (the "Bardet process"), a substance similar to paper pulp could be produced out of small mica fragments, yielding "mica paper." Bardet, in his later years, served as Director of Hydrology Research (in Paris?); he died on June 24, 1949, but was finally granted a U.S. patent on the process posthumously in 1951. Bardet's mineral collection must have been substantial at the time it was liquidated; the highest catalog number among the Bardet specimen labels in the Mineralogical Record Label Archive is 5,621.
