Monoyer, born on May 9, 1836, also developed the diopter, which is the unit of measurement for vision that is used even today. The diopter measures the distance you’d have to be from text to read it. So, basically, in the chart most of us are familiar with, every row represents a different diopter, from smallest to largest.

Monoyer was born in the French food capital of Lyon, and moved to the University of Strasbourg in 1871. He taught at various universities, including the University of Lyon from 1877 to 1909. Monoyer died in his hometown on July 11, 1912, at the age of 76.
