The Measure of All Things
In June 1792, the erudite and cosmopolitan Jean-Baptiste-Joseph Delambre and the cautious and scrupulous Pierre-Francois-Andre Mechain set out from Paris -- one north to Dunkirk, the other south to Barcelona to calculate the length of the meter. In the face of death threats from village revolutionary councils, superstitious peasants, and civil war, they had only their wits and their letters to each other for support. Their findings would be used to create what we now know as the metric system. Despite their painstaking and Herculean efforts, Mechain made a mistake in his calculations that he covered up. The guilty knowledge of his error drove him to the brink of madness, and in the end, he died in an attempt to correct himself. Only then was his mistake discovered. Delambre decided to seal all evidence of the error in a vault at the Paris Observatory. Two hundred year later, historian Ken Alder discovered the truth. With scintillating prose and wry wit, Alder uses these previously overlooked letters, diaries, and journals to bring to life a remarkable time when everything was open to question and the light of reason made every dream seem possible.

- Relatedly, I recommend reading "The Measure of All Things" by Ken Alder about the origins of the metric system and the first scientific conference ever. It is a surprisingly gripping read.

- On this topic, I recommend reading "Measure of All Things" by Ken Alder. It is a book about the origins of the metric system and how it is partially based on forged data. Méchain did not trust his own excellent surveying observations (the meter was defined as a 1/10^7 from equator to N. pole so they surveyed a fraction of the prime meridian) and modern error analysis did not exist yet thus he made up results to make himself look good. You can get it for $4 used at Abe Books.
- Actual caricature portrait of Adrien-Marie Legendre (not reproduced in the article): https://upload.wikimedia.org/wikipedia/commons/0/03/Legendre...
Legendre made many major contributions to mathematics, but perhaps the most well-known (for folks here) is the method of least squares for curve fitting.
For those interested in the science and politics of the French Revolution period and how methods like least squares were first applied, a wonderful history (in which Legendre plays a supporting role) is Ken Alder’s The Measure of All Things: The Seven-Year Odyssey and Hidden Error That Transformed the World. (“The truth belongs to everyone, but error is ours alone.”)
