"Paul Tannery (1843\u20131904) was a French mathematician and historian of mathematics. He was the older brother of mathematician Jules Tannery, to whose Notions Math\u00E9matiques he contributed an historical chapter. Though Tannery's career was in the tobacco industry, he devoted his evenings and his life to the study of mathematicians and mathematical development."@en . "1843Z"^^ . . . "French mathematician" .
