Blaise Pascal, 1623-1662, was a man vastly ahead of his time. Inventing history’s first widely usable calculator when he was just 23, Pascal was heralded as a genius by the grandest of all European kings, Louis XIV.
His calculator - the Pascaline - ingeniously turned the latest advancements in clock making towards arithmetical computation. The resulting machine was surprisingly compact and efficient. It used gears and capture mechanisms to instantly add or subtract very large numbers without error or need for advanced operator training.
Beyond his skills in mathematical engineering, Pascal was also a physicist, writer and theologian.
Naturally, this visionary man inspired a watch design from Divided by Zero, check out the Pascal.
