Concerns Founded Year

Currently States 1871

Edward Burnett Tylor's Primitive Culture (1871) established the discipline's central concept of culture and is commonly cited as founding the modern academic discipline; institutional roots reach back earlier still, to the Ethnological Society of London (1843) and the Societe d'Anthropologie de Paris (1859).

Antisepsis, Concepts

Standing Scholarly debate

Concerns Proposed By

Currently States Joseph Lister and Ignaz Semmelweis

Lister is generally credited with founding antisepsis as a named surgical practice, since he adopted carbolic acid specifically after learning of Pasteur's germ theory in 1865 and published his method for other surgeons to follow. Ignaz Semmelweis reached the same practical conclusion, that something transmitted on unwashed hands caused fatal infection, at Vienna General Hospital in 1847, nearly two decades before Lister and with no germ theory available to explain why it worked; his results were as dramatic as Lister's but were largely dismissed by his contemporaries for lacking that explanation, and he received little credit in his own lifetime. This atlas records both as originators of the underlying practice rather than resolving which of them the label properly belongs to.

Currently States 1903

The German term Biochemie was already in use by 1877 through Felix Hoppe-Seyler, but biochemistry as a named, independent discipline is more often dated to Carl Neuberg's 1903 coinage of the modern term and the early 20th century institutional consolidation that followed, including the founding of the Biochemical Society in London in 1911.

Botany, Disciplines

Standing Scholarly debate

Concerns Founded Year

Currently States 1753

Botany has no single founding date. Theophrastus is traditionally called the father of botany for Historia Plantarum in the late fourth century BCE, the first systematic descriptive treatment of plants; John Ray produced a rigorous classification in 1686 to 1704; and Linnaeus's Species Plantarum (1753) is recorded here as the field's modern scientific founding because it is the official starting point for plant nomenclature still used today.

Prandtl's 1864 dairy centrifuge is the earliest widely cited practical device; Theodor Svedberg's ultracentrifuge, developed through the 1920s and recognized by the 1926 Nobel Prize in Chemistry, is the version most directly tied to the instrument's scientific use.

Clara Immerwahr, Scientists

Standing Scholarly debate

Concerns Description

Currently States Historians dispute why Clara Immerwahr took her own life. A widely repeated account, popularized by a 1993 biography, holds that she acted principally in protest of her husband's direction of chemical warfare, and some contemporaries described a bitter argument between the couple the night before her death. Researchers including Bretislav Friedrich and Dieter Hoffmann have argued this reading is too simple and is hard to reconcile with surviving letters; they point instead to an accumulation of personal strain, including the recent deaths of her doctoral advisor Richard Abegg and a close friend, professional isolation after a promising start to her own scientific career, and difficulty in her marriage that had little to do with gas warfare specifically. No surviving document written by Immerwahr herself states her reason, and scholars caution against reading her, one way or the other, through present-day assumptions about what a woman scientist of her time would have believed.

Status is debated rather than attested because no letter, note or diary entry from Clara Immerwahr herself survives to state her reason; the protest reading and the personal-strain reading are both built from secondhand and circumstantial evidence, and historians including Bretislav Friedrich and Dieter Hoffmann have argued in print against treating the popular protest reading as settled, a dispute the Science History Institute's own account of her death confirms is unresolved.

Concerns Founded Year

Currently States 1956

1956 marks the intellectual founding, when researchers across psychology, linguistics and the new field of artificial intelligence converged on treating the mind as an information-processing system. The field's institutional founding came later and separately: the Cognitive Science Society was incorporated in 1979. Sources distinguish the two moments rather than settling on one founding date.

DNA Double Helix, Theories

Standing Scholarly debate

Concerns Proposed By

Currently States James Watson and Francis Crick

Watson and Crick are the credited authors of the published 1953 model, but it rested directly on X-ray diffraction data produced by Rosalind Franklin, most centrally her Photograph 51, which reached them through her colleague Maurice Wilkins without her knowledge or permission; their Nature paper credited her only in a footnote as an unpublished source. Franklin died in 1958, four years before the 1962 Nobel Prize for the structure went to Watson, Crick and Wilkins; Nobel Prizes are never awarded posthumously, so whether she would have shared it is debated, but that her data was essential to the model is not.

Wikipedia calls the 1835 Nuremberg salt test an early example of a double-blind protocol, not a formal proposal, and does not credit one inventor of the design; single-blind precedents go back further still.

Eddington Eclipse Expedition of 1919, Experiments

Standing Scholarly debate

Concerns Key Finding

Currently States The observed stellar displacement matched Einstein's general-relativity prediction for how the Sun's gravity bends starlight, rather than the smaller Newtonian prediction, and was reported at the time as the first observational confirmation of general relativity.

Contemporary critics argued the Sobral data were unreliable and that Eddington favoured the relativistic result; a 1979 re-analysis using modern methods validated Eddington's original conclusions and traced the disputed Sobral discrepancy to a telescope defect recognised by contemporary astronomers. See the paired Dissent record on this fact.

Falsifiability, Concepts

Standing Scholarly debate

Concerns Description

Currently States Falsifiability is the philosopher Karl Popper's proposed criterion for what counts as a scientific claim: a theory is scientific only if it forbids some possible observation, so that a real result could in principle show it false. Popper set this out in his 1934 book Logik der Forschung, translated into English in 1959 as The Logic of Scientific Discovery, aiming it specifically at theories he judged unfalsifiable, including certain readings of Freudian psychoanalysis and Marxist history. It has never settled into an uncontested rule: critics, including Popper's own successor Imre Lakatos, argue that real theories are rarely tested and discarded in isolation the way a strict falsificationist story implies, since an anomalous result can often be blamed on an auxiliary assumption instead, a problem known as the Duhem-Quine thesis; it remains a widely taught first criterion rather than a settled last word on demarcation.

No single founding date is recorded for herpetology as a discipline; 1913 marks the founding of the journal that became Ichthyology & Herpetology, an early institutional marker of the field's professionalization, with the American Society of Ichthyologists and Herpetologists following in 1915.

Hypatia, Scientists

Standing Scholarly debate

Concerns Birth Year

Currently States 370

Historians disagree on her birth year by two decades. One camp, following Richard Hoche's nineteenth century reasoning from the timing of her scholarly output, places her birth around 370 CE, the year recorded here. A second camp argues for a birth around 350 CE, reasoning from ancient descriptions of her as an elderly woman at her death in 415. No contemporary record states her age directly, so the disagreement cannot be settled from the surviving sources.

Imre Lakatos, Scientists

Standing Scholarly debate

Concerns Description

Currently States Imre Lakatos was a Hungarian-born philosopher of mathematics and science, born in Debrecen in 1922 and died in London in 1974. He fled Hungary in 1956 after the Soviet suppression of the Hungarian Uprising and settled in Britain, where he taught at the London School of Economics alongside, and eventually succeeded, Karl Popper. His Methodology of Scientific Research Programmes reframes Popper's falsifiability criterion: rather than a single theory being falsified and discarded by one bad result, Lakatos argued science actually proceeds through research programmes, a protected core of assumptions surrounded by auxiliary hypotheses that absorb anomalies, and a programme is judged progressive or degenerating by whether it keeps predicting genuinely new facts or only patches itself to survive old ones. Whether this rescues Popper's demarcation project or quietly concedes its central claim, that a clean falsifying test exists at all, remains argued in the philosophy of science literature; Lakatos himself presented it as a refinement, not a rejection, of falsifiability.

Whether the Methodology of Scientific Research Programmes rescues Popperian falsificationism or effectively abandons its central claim, since a research programme's protective belt can absorb almost any anomaly, is argued between Lakatos's own defenders and critics including Feyerabend, and is not settled by this atlas.

Britannica states plainly that the inventor is not definitively known; the earliest microscopes are traditionally credited to Dutch spectacle makers Hans and Zacharias Janssen and to Hans Lippershey around 1590, but the attribution traces to 1655 testimony given decades after the fact and is treated by historians as unreliable.
