Ernest Lebon

Ernest Lebon (1846–1922) was a French writer and compiler best remembered for biographical and bibliographical works on leading mathematicians of his time. Records from the Bibliothèque nationale de France list a substantial body of work under his name, including studies of Henri Poincaré, Gaston Darboux, and Émile Picard.

His books aimed to make scholarly lives easier to follow: not just telling a scientist's story, but also organizing their publications in a systematic way. That mix of biography and bibliography made his work especially useful for readers who wanted both a human portrait and a guide to the mathematics.

Lebon also published works on prime factors and large numerical tables, suggesting a practical interest in calculation as well as literary documentation. A reliable portrait image could not be confirmed from the sources reviewed during this search, so no profile image is included.
