RODET, Léon. 1832? — 1895. French Oriental Scholar and Historian of Mathematics. Several internet sources (e.g. wikidata) give the impossible 1850 as his birth year (1832? in DataBnF). Studies at École polytechnique, Paris, then living in Paris styling himself only as a member of Société Asiatique, which perhaps indicates employment outside scholarship. One L.R. was in 1859 “Inspecteur de la Fabrication à la Manufacture Impériale des Tabacs” (www.gazette-drouot.com/lots/10103134). In his study of al-Khwārizmī he tried to disprove all Indian influence in his work.
