Carlo Gatti (1817–1878) was a Swiss entrepreneur in the Victorian era. He came to England in 1847, where he established restaurants and an ice importing business. He is credited with first making ice cream available to the general public. He moved into music halls. He returned to Switzerland in 1871, leaving his businesses in the hands of members of his family. He died a millionaire.
Gatti originated in Canton Ticino, the main Italian-speaking area of Switzerland. He was probably born in Marogno, a village within the then commune of Dongio, where he also ended his days. He was the youngest of a family of six, his parents being Stefano and Apollonia. In 1839 Carlo was married to Maria Marioni, by his eldest brother Giacomo, the priest at Castro.
Carlo had moved to London by 1847 at the latest, and lived in the Italian community in Holborn. At first, he ran a stall selling waffles and chestnuts. In 1849, he began to run a café and restaurant with partners. They specialised in selling chocolate and ice cream. They put a chocolate-making machine in the window to attract business, and took ice for the ice cream from Regent's Canal under a contract with the Regent's Canal Company. Their shop was the first to sell ice cream to the public; previously, ice cream was an expensive treat confined to rich people with access to an ice house.
Gatti exhibited his chocolate-making machine, imported from France, at the Great Exhibition in 1851. Also in 1851, Gatti opened a stand in Hungerford Market, near Charing Cross, to sell pastries and ice cream. A portion of ice cream was sold for one penny served in a shell, perhaps the origin of the penny lick.
