Medicine Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

1846 marks William Mortons public Massachusetts General Hospital ether demonstration, the most widely credited moment, but Crawford Long had used ether surgically in 1842 without publishing, and Horace Wells had demonstrated nitrous oxide in 1845 to a skeptical audience.

Priority among Morton, Long and Wells was disputed in their own lifetimes and remains a genuinely debated question among historians of medicine, not a settled attribution.

Currently States 1846
Anesthesia's origin year as a TREATMENT is dated here, as it commonly is, to William Morton's 1846 public ether demonstration, the moment the practice began to spread; the underlying priority dispute over who first achieved surgical anesthesia (Morton, Crawford Long in 1842, or Horace Wells in 1844-45) is carried on the Anesthesia discovery entity, since it concerns credit for the discovery rather than the date the treatment took hold.

AZT was approved as the first antiretroviral drug in 1987, but single-drug treatment alone did not durably control the virus; the therapy's more meaningful origin as an effective, chronic treatment is often dated instead to 1996, when combination therapy was shown to suppress HIV long-term.

Ayurveda, Origin PeriodThe Charaka Samhita and Sushruta Samhita were compiled and redacted over many centuries by multiple authors rather than at a single date by a single author; historians place the Charaka Samhita's core content anywhere from the seventh century BCE to the early centuries CE, with a major redaction around 400 CE.

Some scholars place the Charaka Samhita's core content as early as the seventh century BCE, others argue its named author cannot have lived later than roughly 100 BCE to 200 CE, and the redactor Dridhabala filled in an estimated twenty percent of missing verses around 400 CE. Several historical figures used the name Sushruta, complicating attribution of the Sushruta Samhita as well.

Concerns Origin Year
Currently States 1901
Dated here to Landsteiner's 1901 discovery of blood groups, which made transfusion reliably safe; the practice of transfusion itself is far older, tracing to Jean-Baptiste Denys's documented but often fatal animal-to-human attempts beginning in 1667, so the origin year depends on whether the treatment is dated to first attempt or to first reliably safe practice.

Cataracts, First Described (Era)Scholars dispute which culture first described or performed cataract surgery. A Sanskrit account attributed to the physician Sushruta describes the couching technique, but neither the authorship nor the exact date of the underlying Sushruta Samhita can be established with certainty. The Greek philosopher Chrysippus of Soli (circa 279 to 206 BCE) left an early explicit written account of couching in Greek sources. A modern historical review concludes it is impossible to say which nation, or which individual, first performed a cataract operation.

Concerns Origin Period
Currently States 1796 cowpox inoculation credited to Edward Jenner; predated by centuries of documented variolation practice in China and elsewhere
The 1796 cowpox trial by Edward Jenner is the credited founding act of vaccination in the clinical record, but variolation, deliberate infection with smallpox scab material, was already documented practice in China by around 1000 CE and was used across parts of Asia and the Ottoman Empire before reaching Britain. Medical historians genuinely debate how much credit belongs to the earlier, less formally documented tradition versus the 1796 experiment that established a scientific method.

Insulin was isolated in 1921, but Best and Collip's biochemical extraction method, developed within days of each other in early 1922, was what made a purified, clinically usable insulin possible; historians still debate how credit for the discovery should be divided among the four researchers, and 1922 is used by some accounts as the true origin year of insulin as a usable treatment.

Currently States Frederick Banting and Charles Best, University of Toronto, with James Collip and J.J.R. Macleod; credit is genuinely contested.
Credited principally to Frederick Banting and his assistant Charles Best, who first isolated a pancreatic extract that lowered blood sugar in diabetic dogs in the summer of 1921; biochemist James Collip then purified the extract to make it safe for human use, and physiology professor J.J.R. Macleod supplied the laboratory the work was carried out in and oversaw it. The 1923 Nobel Prize in Physiology or Medicine went to Banting and Macleod alone, a decision Banting protested publicly by sharing his prize money with Best, prompting Macleod to share his in turn with Collip; who most deserves credit for the isolation remains a genuine, sourced dispute rather than a settled attribution.
