Henri Victor Regnault (July 21, 1810 - January 19, 1878) was a French chemist and physicist best known for his careful measurements of the thermal properties of gases.
Working under Justus von Liebig at Giessen, Regnault distinguished himself in the nascent field of organic chemistry by synthesizing several chlorinated hydrocarbons, and he was appointed professor of chemistry at the University of Lyon.
In 1840, he was appointed the chair of chemistry of the Ecole Polytechniqe, and in 1841, he became a professor of Physics in the College de France.

 Henri-Victor Regnault
He also studied the alkaloids and organic acids, introduced a classification of the metals according to the facility with which they or their sulphides are oxidized by steam at high temperatures, and effected a comparison of the chemical composition of atmospheric air from all parts of the world.
Regnault executed a careful redetermination of the specific heats of all the elements obtainable, and of many compounds solids, liquids and gases.
Regnault never recovered from the double blow, and, although he lived until the 19th of January 1878, his scientific labors ended in 1872.

JEAN BAPTISTE REGNAULT (1754-1829), French painter, was born at Paris on the 9th of October 1754, and died in the same city on the 12th of November 1829.

 Henri Regnault - Wikipedia, the free encyclopedia
Alexandre-Georges-Henri Regnault (October 31, 1843 - January 19, 1871), French painter, born at Paris, was the son of Henri Victor Regnault.
At Rome, moreover, Regnault came into contact with the modern Hispano-Italian school, a school highly materialistic and inclined to regard even the human subject only as one amongst many sources whence to obtain amusement for the eye.
The war arose, and found Regnault foremost in the devoted ranks of Buzenval, where he fell on the 19th of January 1871.

Regnault was a skillful, thorough, and patient experimenter that carefully determined (or redetermined) the specific heat of many solids, liquids, gases, the vapor pressure of water and other volatile liquids, as well as their latent heat at different temperatures.
He devoted all his life to perform very accurate measurements and placed in the hands of the modern physicist and chemist aninvaluable collection of constants, which presently are in daily use not only in the laboratory but also for a large variety of industrial purposes.
Regnault was the victim of an implacable fatality that filled his life with personal tragedy, but only in the last years of his life he let it overcome him.

Regnault ne renonçait cependant pas à la Chimie ; car c'est en 1848 qu'il commença la publication de son Cours élémentaire, devenu depuis un ouvrage en quatre volumes ; livre clair et substantiel, quoique peu fait pour exciter l'amour de cette science chez ceux qui souhaitent d'y trouver autre chose qu'une énumération méthodique de réactions.
Regnault avait atteint l'apogée de sa gloire, quand une chute, qu'il fit en 1856 dans son laboratoire, mit pendant un mois sa vie en danger.
Après tant de coups douloureux, Regnault, que sa foi religieuse avait soutenu, s'était encore flatté de trouver près de Genève, dans la gracieuse hospitalité de son ancien élève Soret, quelque repos et, peut-être aussi, la possibilité de renaître au travail.

He began his graduate studies in chemistry, physics, and mathematics at the University of Gottingen in his hometown (the same school at which his father taught), earning his doctorate in 1830.
Using grant money awarded by the Hanoverian government, Bunsen spent several years traveling in Europe, visiting Berlin, Bonn, Paris, and Vienna, and meeting with such prominent scientists as Joseph Louis Gay-Lussac, Henri-Victor Regnault (1810-1878), and Cesar Despretz (1798-1863).
Upon his return Bunsen served on the academic staff of several universities before accepting a position at the University of Heidelberg in 1852, a post he held until his retirement in 1889.
