Michele Rech (Italian: [miˈkɛːle ˈrɛk]; born 12 December 1983), known as Zerocalcare ([ˌdzɛrokalˈkaːre]), is an Italian cartoonist. His pen name, meaning "zero limescale", is based from a TV commercial jingle for a descaler product that came to his mind when he had to quickly come up with a Internet nickname.
