Jean Paul Vuillemin
He studied at the University of Nancy, earning his medical doctorate in 1884. In 1892 he obtained his doctorate in sciences at the Sorbonne, and from 1895 to 1932 he was a professor of natural history at the medical faculty in Nancy.
In 1901 he transferred the yeast-like fungus that was named Saccharomyces hominis by Otto Busse and Saccharomyces neoformans by Francesco Sanfelice to the genus Cryptococcus due to its absence of ascospores. The French Academy of Sciences awarded him the Prix Montagne for 1902.
