Chemistry without catalysis would be a sword without a handle, a light — Chemistry

"Never before has mankind had to face the possibility of extinction in all-out fusion bomb war, nor has it had occasion for hope of unexampled prosperity in the taming of that same fusion bomb. Either fate could result from a single branch of scientific advance. We are gaining the knowledge; science is giving us that. Now we need wisdom as well."

"The chemists are a strange class of mortals, impelled by an almost insane impulse to seek their pleasures amid smoke and vapour, soot and flame, poisons and poverty; yet among all these evils I seem to live so sweetly that may I die if I were to change places with the Persian king."

"The important point is not the bigness of Avogadros number but the bigness of Avogadro."

"Like a chemist, Napoleon considered all Europe to be material for his experiments. But in due course, this material reacted against him."

"Be a physical chemist, an analytical chemist, an organic chemist, if you will; but above all, be a chemist"

"Chemistry is not a primitive science, like geometry or astronomy; it is constructed from the debris of a previous scientific formation; a formation half chimerical and half positive, itself founded on the treasure slowly amassed by the practical discoveries of metallurgy, medicine, industry, and domestic economy. It has to do with alchemy, which pretended to enrich its adepts by teaching them to manufacture gold and silver, to shield them from diseases by the preparation of the , and finally to obtain for them perfect felicity by identifying them with the soul of the world and the universal spirit."
