In 1808, Pellegrino Turri built the first typewriter so that his blind lover, Countess Carolina Fantoni da Fivizzano, could write letters more legibly.

He believed fervently in the power of electronic letters, because electronic messaging was the best way to communicate with his wife, who was deaf, while he was at work.
