László József Bíró (Hungarian: [ˈlaːsloː ˈjoːʒɛf ˈbiːroː];  Schweiger; 29 September 1899 – 24 October 1985), Hispanicized as Ladislao José Biro, was an Argentine, Hungary-born Jewish inventor who patented the first commercially successful modern ballpoint pen. The first ballpoint pen had been invented roughly 50 years earlier by John J. Loud, but it was not a commercial success.
