According to the book by James Hoffman, the cappuccino was known in the 1800s, it was prepared in Vienna. However, I suggest that you draw your attention to a more revealing history of cappuccino in Italy, which had a great influence on this drink.
The first news of cappuccino in Italy appeared at the beginning of the 20th century. Rich in coffee traditions, Italy created its own vision of cappuccino and complemented the world view of it.
The National Institute of Italian Espresso has formulated the following definition:
"25 ml of espresso and 100 ml of steamed milk.. Certified Italian cappuccino has a white color and a dark brown border. The foam is thick, with a minimum number of bubbles."
