Charles VII Orders a "Well-Qualified Agent" from his Royal Mints to Travel to Mainz to Learn Printing (October 4, 1458)

According to manuscript records of the French royal mint on October 4, 1458 Charles VII of France ordered the masters of his mints to find a well qualified agent to go to Mainz to learn the art of printing which had recently been invented by Johann Gutenberg, a man adept at cutting punches and 'caractères'. Nicholas Jenson, for some time mint master at Tours was selected for the mission.

This was the first contemporary reference acknowledging Gutenberg as the inventor of printing.
