Daniel Berthelot (c1865-1927)


1927 Obituary[1]

"The Late Professor Daniel Berthelot.—-The death occurred recently in Paris of Professor Paul Alfred Daniel Berthelot, who was sixty-two years of age. He was one of the four sons, two well known as politicians, of Marcellin Bertlielot, who made his name by researches on fats (glycerin), explosives, thermo-chemistry and photo chemistry, and who is sometimes confounded with Comte de Bortliollet, one of tho great chemists of the French Revolution, who died in 1822, five years before Marcellin Berthelot was born ; the two worked in similar fields. Daniel Berthelot followed his father in the line of his studies, and he claimed that the law of photo-chemical equivalence and the quantum theory, usually connected with the name of Einstein, had been recognised by bis father in 1875, in his general considerations of the atomic theory. The son, who was professor at the Ecole Superioure de Pliarmacie, expanded these views."
