#1: Isaac Newton (1643–1727)
Isaac Newton occupies the top position in most scientists' rankings. His "Annus Mirabilis" of 1665–66 produced calculus, the foundations of optics, and the law of universal gravitation — more foundational science in 18 months than most minds produce in a lifetime. His "Principia Mathematica" (1687) gave humanity its first complete mathematical description of the physical world. Read more in our Newton IQ article.
#2: Albert Einstein (1879–1955)
Einstein's general theory of relativity (1915) replaced Newton's gravitational framework with a geometric description of curved spacetime — and has passed every experimental test for over a century. His special relativity, E=mc², and photoelectric effect work make 1905 the most productive single year in physics since Newton's plague year. Estimated IQ: ~160.
#3: Charles Darwin (1809–1882)
Darwin's theory of evolution by natural selection, presented in "On the Origin of Species" (1859), is arguably the most important idea in the history of biology. It unified all of life science under a single explanatory framework, explaining the diversity and adaptation of all living things. Its implications extended far beyond biology into philosophy, social science, and our understanding of the human condition.
#4: Marie Curie (1867–1934)
Marie Curie remains the only person in history to win Nobel Prizes in two different sciences — Physics (1903) and Chemistry (1911). She discovered the elements polonium and radium, developed the theory of radioactivity, and pioneered techniques for isolating radioactive isotopes. She did much of this work under conditions of significant discrimination as a woman in early 20th-century science.
#5: Michael Faraday (1791–1867)
Faraday — the blacksmith's son who became a scientific giant — discovered electromagnetic induction (the principle behind every electric generator and transformer ever built), the laws of electrolysis, the relationship between light and magnetism, and introduced the concept of the electromagnetic field. Every electric motor, generator, and transformer in existence is based on Faraday's discoveries. See our geniuses born poor article.
#6: Alan Turing (1912–1954)
Alan Turing invented the theoretical foundations of computer science (the Turing machine, computability theory), cracked Nazi Germany's Enigma codes at Bletchley Park (directly contributing to Allied victory in WWII), and laid the groundwork for artificial intelligence with his 1950 paper "Computing Machinery and Intelligence." Every computer ever built is a physical instantiation of the Turing machine concept.
#7: Richard Feynman (1918–1988)
Richard Feynman won the Nobel Prize in Physics (1965) for his work on quantum electrodynamics (QED), which is the most precisely tested theory in physics. He invented Feynman diagrams — a diagrammatic method for calculating particle interactions that transformed how quantum mechanics is used. He was also the greatest physics teacher of the 20th century, whose "Feynman Lectures on Physics" remain definitive.
#8: Niels Bohr (1885–1962)
Niels Bohr developed the Bohr model of the atom (1913), was the leading interpreter of quantum mechanics, and founded the Copenhagen Institute for Theoretical Physics that became the global center of physics between the wars. His philosophical work on complementarity — the idea that quantum phenomena require seemingly contradictory classical descriptions — shaped how physicists think about the relationship between observation and reality.
#9: James Clerk Maxwell (1831–1879)
James Clerk Maxwell's four equations of electromagnetism unified electricity, magnetism, and light into a single theoretical framework — one of the great unifications in scientific history. His equations predicted the existence of electromagnetic waves and calculated their speed, which turned out to be the speed of light — establishing that light is electromagnetic radiation. Einstein called Maxwell's achievement "the most profound and the most fruitful that physics has experienced since the time of Newton."
#10: Louis Pasteur (1822–1895)
Louis Pasteur's germ theory of disease — the demonstration that specific microorganisms cause specific diseases — is the foundation of all modern medicine. He developed vaccines for chicken cholera, anthrax, and rabies; invented pasteurization; and his work fundamentally transformed surgery, sanitation, public health, and our understanding of infectious disease. He also disproved spontaneous generation (the idea that life arises from non-living matter) through his elegant swan-neck flask experiments.
