Blaise Pascal Invented The First Form Of A Calculator
Blaise Pascal was a 17th-century child prodigy and mathematician. The self-taught mathematical genius was wowing the time’s most influential thinkers by age 12. By the time he was 15 he published his first original mathematical work, Essai pour les coniques. Descartes found the publication to be so brilliant he accused Blaise’s father, Etienne of writing the piece and passing it off as his son’s to impress the public. Blaise soon after invented the first mechanical calculating machine that could add and subtract, a very early predecessor of the calculator and sold it to local businesses. He continued to publish works across Europe until his death in 1662.
