By Bernard Jaffe

This booklet is a vintage within the box of well known technological know-how. general interpreting because the Thirties, it truly is one of many few historeis of chemistry to be aware of the lives of the good chemists. via those dramatic and human tales, it provides an authoritative and enjoyable account of the good discoveries and advances during this clinical box. After many printings in 3 past variants, this e-book has been newly revised via the writer for this fourth edition.
Beginning with Trevisan and his lifelong look for the "philosopher's stone," the writer narrates the lives and discoveries of such towering figures as Paracelsus and his chemical therapy of affliction; Priestley searching for phlogiston and discovering oxygen and carbon dioxide, Lavoisier making a new language of chemistry; Dalton and his Atomic thought; Avogadro and the assumption of molecules, Mendeleeff arranging the desk of parts lower than his Periodic legislation; the Curies separating radium; Thomson gaining knowledge of the electron; Moseley and his legislations of Atomic Numbers; Lawrence and the development of the cyclotron; and extra. essentially the most dramatic bankruptcy within the ebook, the account of the improvement of nuclear fission, ends the tale of chemistry at its such a lot enormous fulfillment. a last bankruptcy discusses the various results of nuclear fission, the invention of nuclear fusion, and the new paintings with subatomic particles.
Bernard Jaffe is the writer of many different technological know-how books and a number of other technological know-how textbooks. Upon the unique book of this publication, Mr. Jaffe acquired the Francis Bacon Award for the Humanizing of data. the yank Chemical Society's historical past of Chemistry department commemorated him in 1973 with its Dexter Award for "distinguished success within the background of chemistry."

Man was no longer to remain captive to the notion that an ape's leg tied around the neck would cure the bite of this beast, nor was medical knowledge to be gained by the scanning of the heavens. And what pernicious nonsense was this singular practice among the old men of Rome of being breathed upon by young girls to prolong their lives I Paracelsus abandoned all this witchcraft and superstition. He started the search for the potent drugs which the alchemist was to prepare or purify. Even the many herbs and extracts in common medical use were placed secondary to the value of these chemicals.

Others before him had obtained gases by heating solids. Scheele, the great Swedish apothecary chemist, had obtained the same results three years before by collecting "empyreal" air. Robert Boyle, a hundred years back, had heated the same red powder and obtained the same mercury. Stephen Hales, too, had liberated a gas from saltpetre but saw no connection between it and air. Eck of Salzbach, an alchemist, had likewise performed this experiment three centuries before in Germany, and yet the world had not been aroused, for nothing further had been discovered about the gas.

Tory many had discussed the fire principle. James Woodhouse, Professor of Chemistry at the University of Pennsylvania, Pierre Adet, French Minister to the United States and devotee of chemistry, and John MacClean of Princeton University, besides Mitchill and Priestley, had threshed out the matter in a friendly spirit. Priestley felt keenly the overthrow of this doctrine. It had served men of science for a century and had pointed out a "The refutation of a fallacious hypothesis," he declared, "especially one that is so fundamental as this, cannot but be of great importance to the future progress of science.
