John Snow was a Victorian physician who helped to establish that cholera was spread by contaminated water (not bad air, as theory had it). He traced the source of a deadly cholera outbreak to one pump and was able to have it closed, ending the outbreak, despite deep resistance from the local authorities, who did not want to believe his theory. This was a massive event in public health and the founding event of the science of epidemiology. Snow was also an early pioneer of anaesthesia.
A dedicated scientist, the results of his work are still evident. He saved untold lives. This is his story.
I received a copy of this book from the author via the Goodreads First-reads giveaway program.
This short biography covers the work of doctor John Snow in investigating outbreaks of cholera in England, a key event in the development of the science of epidemiology, tracing an illness back to its source and ultimate cause. Although Snow was no microbiologist, and it fell to Koch to eventually clearly identify the bacteria Vibrio cholera as the causative agent of the disease, Snow's work laid the foundations for establishing a way to control cholera, namely to focus on water supplies rather than the prevailing view of the time, 'bad air'.
Challoner, an established writer of communicating science to a lay audience, particularly youth, writes this geared for older children and young adults, but for those unfamiliar with Snow's work and epidemiology, it would be quick, highly readable primer on the topic. Challoner focuses on the cholera-related work of Snow, rather than writing an all-encompassing birth-to-death biography, though he does discuss tangentially Snow's role as physician and pioneering anesthesiologist.
Despite focusing on this history of science and medicine, Challoner relates the story with descriptive warmth, including small details of everyday life at the time (mid-late 1800s) and conversationally, anecdotally through the thoughts of Snow and those he comes in contact with in his endeavors. Though fabricated in that retelling, the facts behind the story, the history, remain solidly accurate to my eye.
Beyond introducing Snow's accomplishments, this book in general outlines the scientific process of mystery, curiosity, research, refinement, and ultimate success, but with more work for others to carry on. In this sense it is a good general introduction of children to science in general.
The only drawback to the book relates to who the audience may actually be. With text alone, it tends towards the dry and detail-laden, including some medical/scientific vocabulary, despite being related in a straight-forward way, more relatable perhaps to an adult. Yet, it is written in a short and succinct manner with phrases interspersed in the detail that seem geared towards the young. It thus seems most appropriate for a teen with a keen interest in science or medicine, or as a fine source for some school project or paper.
I enjoyed getting to read about the thought process of the doctor/scientist/epidemiologist John Snow regarding cholera. It was interesting to read what it would be like to have the majority of your colleagues think your theories are wrong but yet see that not damper his motivation. It was a nice easy read that someone who is interested in diseases and epidemiology would enjoy. It is not extremely difficult either in the terms of the needed scientific knowledge.
