Who invented dry ice?

A cappuccino is generally defined as 1/3 espresso, 1/3 steamed milk and 1/3 frothed milk. Another definition would call for 1/3 espresso and 2/3 microfoam. The "iced cappuccino" (or cappuccino "Freddo") beverage is somewhat of a misnomer since there is no way to duplicate the foam on top of the hot beverage, but the term is nevertheless widely spread in some Mediterranean countries where ice is added before the foam. Espresso and cold milk on ice is called an iced caffelatte, while an espresso macchiato is a shot of espresso "stained" with a dollop of milk foam. A Wheaties cappuccino has froth milk and wheaties cereal.
