Science Is Not Alternative Facts – Part 1

Walter Clement Noel, born in 1884 was a 20 year-old black male from Grenada studying dentistry in Chicago. In 1904, Noel took ill and was admitted to Chicago Presbyterian Hospital, suffering from respiratory symptoms and general malaise. Medical intern Dr. Ernest Irons performed the initial medical work-up on Walter Noel and presented his findings to his Attending Physician Dr. James Herrick. Both Dr. Herrick and the young Dr. Irons felt Walter Noel had malaria. A person from a near equatorial Caribbean island such as Grenada presenting in the United States with malaria was not terribly unusual, but what happened next was.

As part of the evaluation, Dr. Irons performed a microscopic peripheral blood smear exam on Noel’s blood, expecting to see tiny malaria parasites. In the early 1900s microscopic examination of a blood smear was relatively new in medical practice, it was like the “in thing” for a doctor to know how to use a microscope. In the 1670s when Dutchman Antonie van Leeuwenhoek having built one of the first microscopes, peered into the world of invisible life. Van Leeuwenhoek used his dimly lit microscope, lit by reflected candlelight no doubt, to describe the microcosm world of bacteria, red blood cells and for reasons that escape history, male sperm. Yet despite van Leeuwenhoek’s seminal work – double entendre notwithstanding – having created the field of microbiology, it took another 200 years, towards the end of the 1800s, for the medical world to catch on and utilize the microscope as part ‘n parcel in medical diagnosis and treatment. After all, microscopes were not that easy to come by, difficult to make and cost more than a pretty coin.

Another reason of course for the delay in understanding the spread of infectious diseases, other than the nascent field of microscopy, was that overpowering one thousand year incorrect theory of Galen of Pergamon, the 3rd Century Greek physician within the Holy Roman Empire who decreed that infection was spread by miasma, by bad air. Galen was brilliant and often insightful; but his dogmatic medical theories, even the wrong ones, persisted through the Dark Ages, through the Medieval Ages, needing Renaissance scientists to bring many of Galen’s false pillars down. It wasn’t until the end of the 19th Century, with the germ theory experiments of the Frenchman Louis Pasteur in 1860 and his pasteurization of milk, that it was proved bacteria caused infection, ushering in fledgling field of microbiology and infectious disease.

Our direct ancestor, Homo sapiens emerged on the World scene in equatorial Africa around 200,000 years ago and it is believed that 100,000 years later malaria for reasons that are not knowable the malaria parasite chose humans as its host, about the same time our ancestors also began migrating out of Africa.
