"Microbe Hunters" With A Present day Sensibility, "The Remedy" Examines Germ Theory"s Scientific Origin And Social Diffusion

I can trace my early profession interests along a vector of science literature that began in elementary school, with Paul de Kruif’s 1926 traditional, Microbe Hunters, continued with Berton Roueche’s great New Yorker “Medical Detective” stories in junior higher, and was followed by Horace Freeland Judson’s Eighth Day of Creation, an inspirational history of molecular biology’s formative years,  in higher school.  When I was touring schools and came across the centrifuge used in the popular Meselson-Stahl experiment carried out to demonstrate the semiconservative replication of DNA, I was offered.


In many ways, the de Kruif stories, written as profiles in heroic science, have aged the least effectively the hagiography retains a certain charm, to be certain, but loses its immediacy and sense of resonance.  I’ve prolonged wished Microbe Hunters could be updated in a way that more fully contextualizes the researchers’ work and achievements – not to tear down these heroes, but to humanize them, representing their accomplishments – and their failures – with greater nuance, but related empathy, even though placing the science in a broader and much more full social context.


In reading through Thomas Goetz’s The Treatment this weekend, I felt that my wish was lastly granted.


Goetz may be ideal acknowledged for a preceding position, Executive Editor of Wired.  Right now, he’s co-founder (with Matt Mohebbi, of Google Flu Trends fame) of the health analytics startup Iodine, and Entrepreneur-in-Residence at the Robert Wood Johnson Basis, and has an abiding, possibly unavoidable curiosity in wellness and medicine.  His late father was a prominent academic diabetologist, his mother worked as nurse for decades, a sister is a training surgeon, and one more sister was tragically killed in Uganda in 1998 while functioning to advance public well being with the Minnesota International Health Volunteers.  He has carried out them all proud with this work.


Goetz’s easy familiarity with medicine suffuses the pages of The Remedy, a thoughtful, patient, in the long run fascinating account of the struggle of 19th century science, and society, to come to grips with the germ concept of illness, and produce new technologies to consider on 1 of humanity’s oldest scourges, tuberculosis.


Goetz focuses on two protagonists in particular, beginning with the German Robert Koch, whose ambition and careful methodology propelled him from obscurity to fame, culminating in the identification of the causative agent of tuberculosis, the elusive Mycobacterium tuberculosis.  We are launched to Koch’s struggles: the righteous,  which includes his disputes with distinguished skeptic Rudolf Virchow, who believed germs had been at greatest the consequence, not result in of ailment the petty — most notably his bitter, ongoing battle with Louis Pasteur for recognition and acclaim and the misguided – such as his mistaken belief that he had recognized a remedy for tuberculosis.  Had he only utilized the rigorous precepts for evidence that he meticulously created, and that had guided his work for years, the tragic error, and ensuing fall from grace, it looks, could easily have been avoided.


Who was arguably the very first person to propose the great Robert Koch may well have been mistaken?  An ambitious British doctor making an attempt to gain traction as a writer, and who had traveled to a scientific demonstration in Berlin expecting to be dazzled by Koch, nevertheless returned disappointed though with a fascinating story to share.


Nevertheless it wasn’t his critique of Koch that catapulted this writer to fame rather, it was the scientific methodology of his character Sherlock Holmes that sooner or later introduced the globe to Arthur Conan Doyle.


However Conan Doyle at some point very medication to concentrate on writing, “Conan Doyle had gotten a great deal out of medicine,” Goetz writes:



“An training, a sense of stature and accomplishment, and most of all, a globe view.  His was by now a thoroughly scientific mind, regardless of whether or not he nevertheless chose to participate in that science.  Healthcare science informed how he considered it influenced how he wrote and really clearly, it was inseparable from what he wrote.”



Conan Doyle’s Holmes – a lot like Koch at his best– was, Goetz observes, “precise, methodical, and keenly perceptive.  He ably appropriates the tactics of the bacteriologist to discern what seems otherwise invisible.”


This method appealed to Conan Doyle’s audience since, as Goetz writes,



“science was longer seen as some radical challenge to European culture instead, it seemed in several approaches to define the culture.  This was real in Germany and France and specifically in Britain, the place science seemed to touch anything in the Victorian spirit.”



Knowing how germ theory manufactured this leap, and evolved from revolutionary science to cultural expectation is Goetz’s preoccupying query – or as he frames it much more generally, “how does a scientific revolution construct towards social modify?”  He continues,



“This is probably the central query of the previous 150 many years, a period when science has, time and once again, transcended a eureka moment in the laboratory to compel a broader cultural shift.  This trajectory lies behind every little thing from nuclear energy to plastics to the Internet.  But as important as this trajectory is for the fabric of our day-to-day lives, the method too usually slips by without having our noting it, or even our know how, exactly, the progress truly takes place.”



Moving from science to culture, Goetz writes, demands two related but distinct actions, characterized by distinct processes and associated with various burdens of evidence.  The initial phase is scientific – achieving the sort of paradigm shift Kuhn describes (and that Jim Manzi nicely reviews in Uncontrolled) by providing compelling information that meet established specifications of evidence – and waiting for holdouts to die off.


The 2nd step – originally conceptualized, Goetz says, by Freeman Dyson – is the “skills and inventions” (to use Dyson’s terms) that come from new scientific concepts.  In this see, as Goetz puts it, “the revolution lives in the sector, not the thought.”  It’s the technology, the industry, the useful outcomes of science that we see around us that eventually permits the revolution to move from science to culture.


As a result, while Koch might have designed the crucial ideas for defining a causative agents – Koch’s postulates continue to be taught in medical school these days – the cultural adoption of this mindset necessary not just concrete examples of good results (this kind of as Pasteur’s renowned demonstration of an anthrax vaccine at Pouilly-le-Fort, which culminated, according to Goetz, with Pasteur raising his arms in triumph and crying “Here is it! Oh ye of small faith!”), but also characters such as Conan Doyle’s Sherlock Holmes, an engaging representation of the scientific procedure Pasteur and Koch refined, preached, and quite frequently, practiced.
