Pierre Eugène Marcellin Berthelot (25 October 1827 – 18 March 1907) was a French chemist and politician noted for the Thomsen-Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances and disproved the theory of vitalism. He is considered as one of the greatest chemists of all time.

Berthelot, often called the founder of modern organic chemistry, was one of France's most celebrated scientists—if not the world's. He was permanent secretary of the French Academy, having succeeded the giant Louis Pasteur, the renowned microbiologist. Unlike Delage, an agnostic, Berthelot was an atheist—and militantly so."

"Although Delage made it clear that he did not regard Jesus as the resurrected Son of God, his paper upset the atheist members of the Academy, including its secretary, Marcellin Berthelot, who prevented its full publication in the Academy's bulletin."
