Auguste-Savinien Leblond

Managing Real Estate Broker with Fathom Realty PB00068179

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.

Good morning Wayne,

The slide rule was a great instrument in its day!

And the goog old USA is still trying to convert to the metric system!

Make yourself an awesome day.

James Dray good morning, James... I'll admit it... even after living in Europe, I never got the hang of calculating anything in metres. Kilograms and liters I got... metres not so much.

I was really good with the slide rule in high school. Then came the hand calculators.

I am more of a visual learner so I would have certainly appreciated his teaching methods and math was always my favorite subject in school.

NOT one of my heros James Dray as I never caught on to the meteric system. Unfortunately for me my Chevy Yukon came from Canada so all the instrumention is in meteric measures.

Hello James - I am still thinking about Leblond growing up in a family of mathematicians.  Imagine the dinner time conversation. . .   How was you day today?  Solve any thing interesting?   Tell me your problem could entail a lengthy discussion that would likely go over my head.

I grew up with meters, kilograms, kilometers. etc.  When we move to America, a whole new system to adopt.  And now when we travel to Europe, I find it a pain to reverse!  LOL A

Yes I'm going to have to brush up on my French history because I didn't know about the meter but I didn't know it was 39 inches roughly. Thank you for sharing James Dray
