The Species Seekers: Heroes, Fools, and the Mad Pursuit of Life on Earth sounds like a cool book, though I’ve not read it yet. From Publisher’s Weekly:

Until about 1834, the word “scientist” didn’t exist. According to naturalist Conniff (Swimming with Piranhas at Feeding Time), it was likely at a meeting of the British Association for the Advancement of Science) where a member, following the model of “artist” and “atheist,” coined a new term–“scientist” reflecting the transition of the nascent study of plants and animals from self-educated hobbyists to a new breed of professional. The author blows the fusty dust of centuries off an exhaustive bibliography of almost 300 books, many published in the 1800s. Conniff tells a fresh story that begins with Swedish botanist Carolus Linnaeus’s creation of a species classification system in 1735, through Darwin’s development of the theory of evolution–and of how, then as now, it was a challenge to religious orthodoxy–to the present as new species continue to be discovered, including in this decade a striped rabbit in the Mekong Delta. Conniff’s parade of pioneers whose colorful exploits are recounted is at times overwhelming, but this history of the “great age of discovery” is spellbinding.
