In Cathedrals of Science, Patrick Coffey describes how chemistry got its modern footing-how thirteen brilliant men and one woman struggled with the laws of the universe and with each other.
They wanted to discover how the world worked, but they also wanted credit for making those discoveries, and their personalities often affected how that credit was assigned. Gilbert Lewis, for example, could be reclusive and resentful, and his enmity with Walther Nernst may have cost him the Nobel Prize; Irving Langmuir, gregarious and charming, "rediscovered" Lewis's theory of the chemical bond and received much of the credit for it. Langmuir's personality smoothed his path to the Nobel Prize over Lewis.
Coffey deals with moral and societal issues as well. These same scientists were the first to be seen by their countries as military assets. Science was not always fair, and many were excluded.
The Nazis pushed Jewish scientists like Haber from their posts in the s. Anti-Semitism was also a force in American chemistry, and few women were allowed in; Pauling, for example, used his influence to cut off the funding and block the publications of his rival, Dorothy Wrinch.
Cathedrals of Science paints a colorful portrait of the building of modern chemistry from the late 19th to the midth century. The exploitation of fire, the development of pigments, and the discovery that metals could be smelted and worked laid the foundations of civilization.
The search for better tools and weapons drove metallurgy, and the need for medicines and perfumes lay behind the first laboratories. This book traces a story of exploration and discovery, from the earliest applications of chemistry by our ancient forebears.
For more than 1, years, alchemists pursued the transformation of matter until the advent of modern chemistry in the 17th century set us on the path to the complex science of today.

The conclusions reached by these studies have become foundational for historians examining the interplay between science and religion in the United States in the twentieth century. However, a reexamination of key twentieth century biology textbooks suggests that the narrative that the treatment of the theory of evolution was held hostage to anti-rational cultural forces is largely a myth, created first as part of a public relations effort by the Biological Sciences Curriculum Study BSCS to differentiate, defend, and promote its work, and later as part of an attempt by scholars to sound a warning concerning the rise of the religious right.
A focus on this narrative has not only allowed biologists to sidestep uncomfortable questions regarding the race-biased and class-biased assumptions embedded within the concept of evolutionary progress, it has also limited reliance on the texts in question as reliable reflections of the cultural assumptions of educators and scientists. A reexamination of the most popular American biology textbooks from to , particularly the work of Ella Thea Smith, provides evidence in support of these contentions.
