  Jean Baptiste Joseph Delambre - LoveToKnow 1911
JEAN BAPTISTE JOSEPH DELAMBRE (1749-1822), French astronomer, was born at Amiens on the 19th of September 1 749.
Here Delambre observed and computed almost uninterruptedly, and in 17 9 0 obtained for his Tables of Uranus the prize offered by the academy of sciences, of which body he was elected a member two years later.
The first consul nominated him inspector-general of studies; he succeeded Lalande in 1807 as professor of astronomy at the College de France, and filled the office of treasurer to the imperial university from 1808 until its suppression in 1815.

 Delambre biography
Delambre was very impressed and decided to make observations of the orbit of Uranus in order to verify Laplace's theoretical results.
The principal landmarks in the development were the tables of Lacaille (1758), and the tables of Delambre that were published in the third edition of Lalande's Astronomie (1792), and the revised version of these tables published by the Bureau des Longitudes in 1806.
Delambre attained further achievements in his career, however, including his appointment to the chair of astronomy at the Collège de France in Paris in 1807.

 Jean Baptiste Delambre
Jean Baptiste Joseph Delambre (1749-1822), an eminent mathematician and astronomer, was born at Aiens, September 19, 1749.
Delambre's Base du system Metrique was published in three volumes (1806-10), which shows that he was still engaged upon it at the time he wrote the letter which forms the basis for this story.
Delambre, who had been chosen as an associate of almost every scientific body in Europe, was appointed in 1795 a member of the French Board of Longitude, and in 1803 perpetual secretary for the mathematical sciences in the Institute.

Named director of the Paris Observatory and professor at the Collège de France, Delambre was one of the first astronomers to derive astronomical equations from analytical formulas, was the author of Delambre's Analogies and, after the age of 70, also the author of works on the history of astronomy like Histoire de l'astronomie.
Jean Baptiste Joseph Delambre died in 1822 and was interred in the Père Lachaise Cemetery in Paris.

Delambre's last years were devoted to researches into the history of science, resulting in the successive publication of: Histoire de l'astronomie ancienne (2 vols., 1817); Histoire de l'astronomie au moyen âge (1819); Histoire de l'astronomie moderne (2 vols., 1821); and Histoire de l'astronomie au XVIII siècle, issued in 1827 undes the care of C. Mathieu.

Delambre wrote the Base du système métrique décimal -- which we might translate as The Foundation of the Metric System -- in order to present all the expedition's findings "without omission or reticence." At over two thousand pages, this magisterial work certainly appears thorough enough.
Yet even in failure, Delambre and Méchain succeeded, for by their labor they rewrote not only our knowledge of the shape of the earth, but our knowledge of error as well.
Delambre and Méchain had demonstrated that the judicious application of scientific knowledge might, as Archimedes once boasted, move the world.

He is noted also for astronomical computations, especially a table of the motions of Uranus, and for discovering four formulas in spherical trigonometry (Delambre's analogies).

He emphasizes the complicated personalities of the two 18th-century Frenchmen who set out to define the proper length of the meter, and their intention to supply the foundation of a new standardized system of measurement, thereby making life more equitable.
As it happened, Méchain's inability to get the results he wanted drove him to an early grave, while Delambre's belated discovery of his partner's deceit turned the younger scientist more philosophical, and launched an era in which accounting for error became an important part of scientific study.
He also writes warmly about their era, when number-crunchers were hailed as "savants"and had the ear of kings and commoners alike, and when science involved strapping on hiking boots and heading into the wild to refine the common understanding.

What neither advocates nor opponents of the metric system could have known is that a secret error lies at the heart of the metric system—an error perpetuated in every subsequent definition of the meter.

 CNN.com - Why the metric system is wrong - Dec. 3, 2002
The new French leaders were determined to create a single standard based on the Earth, and assigned two astronomers, Jean-Baptiste-Joseph Delambre and Pierre-Francois-Andre Mechain, to travel the French countryside along the Paris meridian to determine its exact length from the English Channel to the Mediterranean.
Jean-Baptiste-Joseph Delambre, one of the two surveyors assigned to determine the meter.
The scientists who created the meter wanted it to be close to the commonly used yard (or aune, in France), so Delambre and Mechain's mission was, in many ways, a fait accompli.

The tale begins with French astronomers Jean-Baptiste-Joseph Delambre and Pierre-Francois-Andre Mechain, who painstakingly set out to measure the meridian between Dunkerque and Barcelona.
Alder, a professor of history at Northwestern University, immersed himself in just about every detail of Delambre and Mechain's mission, which Louis XVI commissioned just prior to the onset of the French Revolution.
Inspired by what he says are clues in Delambre's seminal book on the metric system -- published after Mechain's death -- Alder unearthed evidence from long-sealed archives indicating that because of an error made by Mechain and covered up by Delambre, the unit that has become the worldwide standard of measure is actually wrong.
