Half a million years ago our ancestors learned to make fire from scratch. They crafted intricate tools from stone and brewed mind-altering elixirs from honey. Their descendants transformed clay into pottery, wool into clothing, and ashes into cleansers. In ceramic crucibles they won metal from rock, the metals lead to colored glazes and glass. Buildings of brick and mortar enshrined books of parchment and paper. Kings and queens demanded ever more colorful clothing and accessories in order to out-class clod-hoppers and call-girls. Kingdoms rose and fell by the power of saltpeter, sulfur, and charcoal. And the demands of everyday folk for glass and paper and soap stimulated the first round of chemical industrialization. From sulfuric acid to sodium carbonate. From aniline dyes to analgesic drugs. From blasting powder to fertilizers and plastics. In a phrase, From Caveman to Chemist. Your guides on this journey are the four alchemical elements; Fire, Earth, Air and Water. These archetypical characters deliver first-hand accounts of the births of their respective technologies. The spirit of Fire, for example, was born in the first creature to cultivate the flame. This spirit passed from one person to another, from one generation to another, from one millennium to another, arriving at last in the pages of this book. The spirit of Earth taught folks to make tools of stone, the spirit of Air imparted knowledge of units and the spirit of Water began with the invention of spirits. Having traveled the world from age to age, who can say where they will find their next home? Perhaps they will find one in you.

This volume moves chemical instruments and experiments into the foreground of historical concern, in line with the emphasis on practice that characterizes current work on other fields of science and engineering.

From the host of "Bill Nye the Science Guy" comes an impassioned explanation of how the science of our origins is fundamental to our understanding of the nature of science

Heinrich Caro (1834-1910) was the inventor of new chemical processes that in the two decades commencing in 1869 enabled BASF of Ludwigshafen, Germany, to take first place among manufacturers of synthetic dyestuffs. The cornerstones of Caro's success were his early training as calico (cotton) printer in Germany, and his employment at a chemical firm in Manchester, England. Caro was a creative research chemist, a highly knowledgeable patent specialist and expert witness, and a brilliant manager of science-based chemical technology. This first full-length scientific biography of Heinrich Caro delineates his role in the emergence of the industrial research laboratory, the forging of links between academic and industrial chemistry, and the development of modern patent law. Major chemical topics include the rise of classical organic chemistry, collaboration with Adolf Baeyer, artificial alizarin and indigo, aniline dyes, and other coal-tar products, particularly intermediates.
