Named after Gaspare Campari, born 1828, in Castelnuovo in Lombardy. At the age of 14, he became an apprentice drink master at the Bass bar in Turin. There he learned the craft of creating original drink recipes based on wines or spirits combined with herbs and flavorings. After a stint at the Cambio restaurant, Campari moved to Milan in 1862, the home town of his second wife. He opened a cafe next to the Duomo, and negotiated his way into opening the Cafe-Patesserie Campari at the main entrance to the Galleria in 1867. When other bars began to purchase bottles of Campari's house bitters, Bitter all' uso d'Hollanda, for resale, his son Davide made sure the Campari name was displayed with it, and created a brand.
