Ennio De Giorgi arrived in Pisa on 1 November 1959 to take up the chair of Analisi Matematica, Algebrica e Infinitesimale, which before him belonged to Leonida Tonelli. Both originally hailed from the Salento region: De Giorgi was born in Lecce, a baroque city considered the “Florence of the South,” whereas Tonelli was from Gallipoli, the “beautiful city” (from kali polis in Greek), protected by white city walls, surrounded by the sea, that face the Ionic Sea from every side.
