Marcellin Berthelot Quotes & Sayings

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.' — Marcellin Berthelot

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.

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. — Marcellin Berthelot
