Oh, here’s a history of caffe latte from this Wikipedia on caffelatte.
Coffee and milk have been part of European cuisine since the 17th century. Caffè e latte, Milchkaffee, café au lait and café con leche are domestic terms of traditional ways of drinking coffee, usually as part of breakfast in the home. Public cafés in Europe and the US it seems have no mention of the terms until the 20th century, although Kapuziner is mentioned in Austrian coffee houses in Vienna and Trieste in the 2nd half of 1700s as “coffee with cream, spices and sugar” (being the origin of the Italian cappuccino).
