Auguste-Savinien Leblond was born in France back in 1760. He came from a family of mathematicians. I don’t have any information on where he went to school or much of anything about his formal education. What I can tell you about him of course is the rest of the story. This one is going to be short so let’s get to it.
He was a teacher of mathematics but he also published works that earned him the esteem of his peers. He is remembered as the inventor of a fixed and universal measurement of length. He also designed mechanical devices called “logarithmic dials”, for converting traditional and metric measures which was abandoned in favor of slide rules. He was employed the Prints Department of the Royal Library, he was particularly interested in what was known as “education through the eyes”, the use of visual methods for teaching.
Now, back to his invention of the fixed and universal measurement. In 1790, he called his unit of measurement the “metre” or “meter” which is 39.37 inches.
