Pellegrino Turri of Italy
Pellegrino Turri of Italy invented carbon paper in 1806. Pellegrino Turri had invented a typewriting machine in Italy by at least 1808, and since "black paper" was essential for the operation of his machine. Interestingly, the invention of "carbon paper" was a means to an end; he was trying to help blind people write through the use of a machine, and the "black paper" was really just a substitute for ink.
The motive behind Turri's invention was his love, Countess Carolina Fantoni, who had become blind. Not much other than that is known about Turri. His family was famous in Italy but he laid low with the exception of his invention for his love.
