, on whose entrance exam he excelled. His curriculum included mathematics, the sciences, and the classics, all of which would be represented in his future academic work. Tannery's life of public service began as he then entered the École d'Applications des Tabacs as an apprentice engineer. As an assistant engineer, Tannery spent two years in the state tobacco factory at

and his positivist philosophy. After the war, his interest in mathematics continued, and Comte's ideas would influence his approach to the study of the history of science. Tannery moved several times with his career in the tobacco industry: to Périgord in 1872, to

in 1877, and to Paris in 1883. Bordeaux had something of an intellectual atmosphere, and though Tannery moved to Le Havre (near his parents, who lived at Caen) at his own request, he would also directly request the move to Paris, where his research and academic pursuits would be able to flourish. It was in Paris that Tannery took on his first two major editorial works. In 1883, he began an edition of
Diophantus Diophantus of Alexandria ( grc, Διόφαντος ὁ Ἀλεξανδρεύς; born probably sometime between AD 200 and 214; died around the age of 84, probably sometime between AD 284 and 298) was an Alexandrian mathematician, who was the aut ...

, and so Tannery had to reduce his efforts in 1886 when he was transferred to Tonneins. Even without access to the Bibliothèque, Tannery remained hard at work, however, as he published two books composed of articles he had been writing for the '' Revue philosophique de la France et de l'étranger'' and for the ''Bulletin de sciences mathematiques''. In 1888, Tannery moved back to Bordeaux, where he studied Greek astronomy and directed the tobacco factory. Two years later, he was back in Paris; he would remain near Paris until his death. Despite a heavy professional workload, he continued to be productive in his work in the history of science. His editions of Diophantus and Fermat were published, along with over 250 articles. From 1890 forward, Tannery's other major work focused on a new edition of Descartes's works and correspondence, on which he collaborated with Charles Adam, an historian of modern philosophy. Scandal arose in 1903 when the

began a search for a new professor of the history of science. Tannery was considered something of a shoo-in; he even began writing his inaugural lecture. Instead, the position went to Grégoire Wyrouboff, who concentrated on modern mathematicians instead of Tannery's classical and seventeenth-century idols. Wyrouboff was also a freethinker, an asset to the secularist Third Republic, while Tannery was Catholic. Tannery died soon thereafter, on 27 November 1904, in Pantin, just outside Paris. His wife, Marie, would survive until 1945, and she published several of his works posthumously, helping to ensure that his legacy would live on. He was an Invited Speaker of the ICM in 1904 in Heidelberg.
