1550 – Napier – bio

John Napier was born in Scotland in 1550 and is known for his contributions to mathematics. He invented logarithms and used a set of marked rods to perform calculations (like an abacus or a slide rule) which became known as “Napiers Bones”. He also established the first consistent use of the decimal point notation for fractions.

Jost Burgi has been credited with simultaneously and independently creating logarithms, but he published after Napier.
