Moissan, (Ferdinand Frédéric) Henri (1852–1907)
French chemist, trained as an apothecary, who was awarded the 1906 Nobel
Prize in Chemistry for isolating fluorine
(1886) and for developing the electric arc furnace (see electric
furnace). With this furnace he was able to prepare samples of several
of the less common metals, such as uranium,
long before modern metallurgy made them commercially available. He also
claimed to have synthesized diamonds.
