Marcellin Berthelot

Pierre Eugène Marcellin Berthelot was a French chemist and Republican politician noted for the Thomsen–Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances, providing a large amount of counter-evidence to the theory of Jöns Jakob Berzelius that organic compounds required organisms in their synthesis. Berthelot was convinced that chemical synthesis would revolutionize the food industry by the year 2000, and that synthesized foods would replace farms and pastures. "Why not", he asked, "if it proved cheaper and better to make the same materials than to grow them?"

We all teach ... the chemistry of Lavoisier and Gay-Lussac.
I do not want chemistry to degenerate into a religion; I do not want the chemist to believe in the existence of atoms as the Christian believes in the existence of Christ in the communion wafer.
One can, then, conceive the production, by purely mineral means, of all natural hydrocarbons. The intervention of heat, of water, and of alkaline metals - lastly, the tendency of hydrocarbons to unite together to form the more condensed material - suffice to account for the formation of these curious compounds. Moreover, this formation will be continuous because the reactions which started it are renewed incessantly.
Within a hundred years of physical and chemical science, men will know what the atom is. It is my belief when science reaches this stage, God will come down to earth with His big ring of keys and will say to humanity, 'Gentlemen, it is closing time.'
Do these fuels result always and necessarily in one way from the decomposition of a pre-existing organic substance? Is it thus with the hydrocarbons so frequently observed in volcanic eruptions and emanations, and to which M. Ch. Sainte-Claire Deville has called attention in recent years? Finally, must one assign a parralel origin to carbonaceous matter and to hydrocarbons contained in certain meteorites, and which appear to have an origin foreign to our planet? These are questions on which the opinion of many distinguished geologists does not as yet appear to be fixed.
