Jean Paul Vuillemin (13 February 1861 – 25 September 1932 in Malzéville) was a French mycologist born in Docelles.
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.
[1] In 1889 he employed the term "antibiotic" when describing the substance pyocyanin.
[2] 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.
[5] In 1912 Vuillemin created the genus Beauveria to honor Jean Beauverie for his work the previous year on the type species - B. bassiana - transferring it from Botrytis.
