John Napier is best known as the discoverer of logarithms. He was also inventor of Napier's Bones. Which were multiplication tables written on strips of wood or bones. The invention was used for multiplying, dividing, and taking square roots and cube roots. He also made common the use of the decimal point in math.
Napier's Bones are an old name for the slide rule, a mechanical method of rapidly doing mathematical operations using logarithms expressed as a divided line.

Sir Oliver Napier was 75 years old (9 days short of 76) when he died on July 2, 2011 (born July 11, 1935).
His parents were relatively young but well-placed in the community. As was the custom, Napier didn't attend school until he was 13 years old, but dropped out fairly quickly. After that, not much is known about his experience until he was 21; some suspect he spent the time travelling in Europe.
