Joseph Oesterle

Also Known As Joseph Oesterlé
Modern

French mathematician, a member of the Number Theory team at the Institut de Mathematiques de Jussieu-Paris Rive Gauche, Sorbonne Universite, who with David Masser formulated the abc conjecture in 1985 while trying to understand the Szpiro conjecture about elliptic curves. Biographical detail beyond his current institutional affiliation was not found in a non-Wikipedia source available to this lane; his birth date is left unwritten rather than asserted from an unverified source.
