Eugène Dumortier (4 December 1802, in Lyon – 12 August 1876, Lyon) was a French paleontologist.
He worked as a manufacturer of gilding and at around the age of 50 his focus turned to geology. He is remembered for a four volume paleontological work on the Rhône-Alpes region that was published from 1864 to 1874.[1] The mineral dumortierite is named after him.[2]
In 1860 he became a member of the Société géologique de France. Also, he was a founding member of the Association lyonnaise des amis des sciences naturelles (1872) and the Société de géographie de Lyon (1873). His large collection of fossils was bequeathed to the natural history museum in Lyon.[1]
