Nephrectomy, Treatments

Standing Scholarly debate

Concerns Origin Year

Currently States 1869

Erastus B. Wolcott performed the first recorded nephrectomy in 1861 in Wisconsin, but the patient died 15 days later; Gustav Simon's planned nephrectomy in Heidelberg on 2 August 1869 is credited as the first with a surviving patient, so sources differ on whether 1861 or 1869 marks the treatment's true origin.

Standing Scholarly debate

Concerns Discoverer

Currently States Alexander Flemings 1928 observation is credited as the discovery, but Howard Florey and Ernst Chains Oxford team turned it into a usable medicine in the early 1940s and share the 1945 Nobel Prize with Fleming for the achievement.

Fleming is credited with the initial 1928 observation; Florey and Chain are credited, alongside Fleming, with making it a practical drug, and all three shared the Nobel Prize in Physiology or Medicine in 1945.

Physical Therapy, Treatments

Standing Scholarly debate

Concerns Origin Year

Currently States 1918

Professional physical therapy is dated here to 1918, when the term Reconstruction Aide came into use for the wartime role trained at Walter Reed Army Hospital; the underlying practices of therapeutic exercise and manipulation are ancient and cannot be assigned a single origin year, and Britain's Chartered Society of Physiotherapy, founded 1894, predates the American wartime program.

Concerns Origin Year

Currently States 1913

A parallel description by John Abel, Leonard Rowntree and B.B. Turner of Johns Hopkins Hospital followed in 1914; both are treated as founding descriptions of the technique, with 1913 the earlier of the two.

Concerns First Described (Era)

Currently States Possible depiction on an Egyptian stele, circa 1400 BCE.

An Egyptian stele from around 1400 BCE, depicting a man with a withered, shortened leg leaning on a staff, is widely, though not universally, interpreted by historians as an early depiction of the disease's after-effects; the identification is probable rather than certain.

Concerns Origin Year

1985 marks the American Academy of Pediatrics sedation-level definitions the practice is built on; the specific term procedural sedation and analgesia was coined later, in the late 1990s, by emergency medicine bodies.

Currently States 1885

Radiotherapy, Treatments

Standing Scholarly debate

Concerns Origin Year

Currently States 1896

Dated here to Victor Despeignes's first recorded therapeutic use of X-rays against a tumor in 1896, a year after Rontgen's discovery; some accounts instead date the treatment's origin to Rontgen's 1895 discovery of X-rays itself, since Despeignes's own attempt was inconclusive and the first clearly documented therapeutic success came about a year later still.

Standing Scholarly debate

Concerns Founding Year

Currently States 900

The earliest documented reference is an early ninth-century Benedictine monastery dispensary at Salerno. A popular legend credits four co-founders of different faiths (a Greek, a Latin, an Arab and a Jew), a story historians treat as legend rather than historical record.

Structure of DNA, Discoveries

Standing Scholarly debate

Concerns Discoverer

Currently States James Watson and Francis Crick published the double helix model in 1953 and shared the 1962 Nobel Prize with Maurice Wilkins, but their model relied directly on unpublished X-ray diffraction data and images produced by Rosalind Franklin, whose contribution was not properly credited at the time and whose role is now recognized as central by historians of science.

Attribution is genuinely contested: Watson and Crick built the model and are the named Nobel laureates alongside Wilkins, but Rosalind Franklin's X-ray diffraction work, especially Photograph 51, was essential evidence used without her knowledge or full credit, and she died in 1958 before any Nobel recognition was possible.

Traditional Chinese Medicine, Medical Specialties

Standing Scholarly debate

Concerns Origin Period

Currently States Traditionally dated from the legendary Yellow Emperor; most twentieth-century scholarship placed its foundational text, the Huangdi Neijing, between the late Warring States period and the early Han dynasty, but newer archaeological finds have shifted the burden of proof toward a later Han-dynasty-or-after dating for most of the received text.

Older historiography dated the Huangdi Neijing's core to the Warring States period (475 to 221 BCE); more recent scholarship based on excavated manuscripts argues most of the received text is later, from the mid-first century BCE or after.

Currently States 1972

Marks the 1972 surgical ligation of the hepatic artery with portal-vein 5-fluorouracil infusion, the precursor procedure the cited source names as the origin from which embolization plus local chemotherapy later developed into transarterial chemoembolization; not a claim about the exact year the combined technique itself was first named or performed.

Vaccination, Discoveries

Standing Scholarly debate

Concerns Discoverer

Currently States Edward Jenner is credited with the 1796 cowpox demonstration that founded modern vaccination, though the underlying practice of deliberate inoculation against smallpox, variolation, was documented earlier in China, India, the Ottoman Empire and parts of Africa.

Jenner is credited with founding vaccination proper; the older practice of variolation it built on and eventually replaced has separate, earlier and geographically distributed origins that predate any single discoverer.

Variolation, Treatments

Standing Scholarly debate

Concerns Origin Year

Currently States 1567

Joseph Needham dates the first well-documented Chinese variolation to 1567-1572; some 18th-century colonial-era accounts claimed a much older Indian origin, but a 2012 scholarly review concluded that claim was likely later propaganda encouraging acceptance of Jenner's vaccine and rejected it as an ancient practice. Which culture first practiced variolation, and how much earlier than the 16th century, remains genuinely unsettled.

Virology, Medical Specialties

Standing Scholarly debate

Concerns Origin Period

Currently States 1892-1898 identification of a filterable infectious agent, credited jointly to Dmitri Ivanovsky and Martinus Beijerinck

Dmitri Ivanovsky showed in 1892 that sap from tobacco mosaic diseased plants passed through filters retaining bacteria, but favored a bacterial toxin explanation. Martinus Beijerinck repeated the work in 1898 and proposed the agent was a new form of infectious agent, contagium vivum fluidum, a soluble living germ. Historians of science genuinely dispute how the discovery credit should be divided between the two.
