In this persuasive history, Conner aggressively pursues evidence of how, since the earliest civilizations, elite scientists have suppressed and excluded lower class innovators while learning from and using their discoveries, often without giving them credit. As Conner notes, many of the ""Great Man"" myths about people like Galileo and Columbus, once believed to have made their contributions to science out of their own genius, have been debunked, but even those persist in the popular imagination, and others have never been addressed. The pages are dense with information and quotes from both primary sources and modern revisionist historians, and Conner tries to cover too much in too little space, but he writes clearly and skillfully shows connections as he ranges across time periods and disciplines from medicine to art to astronomy. However, despite promising to highlight women's important role in the sciences, they are mostly absent, and the brief chapter on modern times mostly concerns itself with corruption in the pharmaceuticals and atomic weaponry industries. Nonetheless, this book is a valuable synthesis of previously spotty attempts to show science's reliance on the anonymous multitudes for many important advances.
