Founded in Milan in 1872 by Giovanni Battista Pirelli (1848–1932), the company initially specialised in rubber and derivative processes and also made scuba diving rebreathers. Thereafter, Pirelli's activities were primarily focused on the production of tyre and cables (for energy and telecommunications).
