Famous Doctors & ScientistsCountryBorn / DiedSpecialist areasNotable Achievements of Famous Doctors & Scientists
Ramón y Cajal, Santiago Spain1852-1934Physics MedicineThe brain researcher discovered that the central nervous system consists of billions of neurons that all communicate via so-called synapses. He was awarded the Nobel Prize for Medicine for his insight in 1906. Find more famous doctors & physicians on previous pages.
Ramsay, William Great Britain1852-1916ChemistryRamsay discovered the noble gases argon, krypton, xenon and neon, and – during the decay of radon – observed the formation of helium. He found a method for determining atomic weights. In 1904 he received the Nobel Prize for Chemistry.
Rhases, Abu Bakr Muham Iran844-926MedicineRhases was one of the most famous doctors in the Middle Ages and also head of a hospital in Baghdad with much success in healing. He wrote more than 131 books about diseases and their treatment (including smallpox and measles) as well as two encyclopedias of Medicine.
Richter, Charles Francis USA1900-1985SeismologyIn 1935 he jointly created with B. Gutenberg the logarithmic units of quake strength. The “Richter Scale” is open ended. I.e. it has no upper end value for particularly strong earthquakes.
Riemann, Bernhard Germany1826-1866Mathematics PhysicsAs a mathematician he was instrumental in non-Euclidean geometry (parallel axiom), the general theory of functions and differential equations.
Roentgen, Wilhelm Konrad Germany1845-1923PhysicsKonrad Roentgen found a new type of penetrating X-rays in 1895 with which he established the foundations of computer tomography and ultrasonography. In 1901 he received the first ever awarded Nobel Prize for Physics.
Rutherford, Ernest (Nobel Prize 1908)New Zealand1871-1937ChemistryThe New Zealander identified three types of radioactivity in 1903: alpha, beta and gamma rays. He discovered the “photoelectric effect” and performed the first artificial nuclear disintegration. This earned him the 1933 Chemistry Nobel Prize.
Schrödinger, Erwin Austria1887-1961PhysicsSchrödinger described wave mechanics as the basis of quantum mechanics (Schrödinger equation) and founded a theory of color perception. He received the 1933 Nobel Prize for Physics.
Siemens, Werner von Germany1816-1892Physics MechanicsWerner von Siemens discovered early on that rubber is suitable as an insulator and in 1849 founded a company to manufacture submarine cables. He also improved the dynamo through the use of an electric rather than a bar magnet.
Stevin, Simon The Netherlands1548-1620Physics MathematicsFounder of modern statics and hydrostatics. Stevin formulated the law of forces; the “hydrostatic paradox” and other laws such as the relationship between force and displacement on an inclined plane.
Strutt, John William Baron Rayleigh Great Britain1842-1919Physics Nobel Prize 1904Researched in the field of optics, electricity, thermodynamics, wave theory, and prepared the discovery of the noble gases (see Ramsay). First to explain why the sky is blue on the basis of light scattering.
Szent-Györgyi, Albert Hungary1893-1986Biology MedicineAmong other things, the Hungarian researched vitamins (and discovered vitamin C), oxidation processes in living organisms, carbon metabolism and muscle biology. For his achievements this famous doctors was awarded the 1937 Nobel Prize for Medicine.
Theophrastos Greece372-288 BCBiology BotanyThe father of botany and student of Aristotle wrote about 400 books. He examined many hundreds of plants in detail, explored their origins, and also examined their medical properties.
Thomson, Sir Joseph Great Britain1856-1940PhysicsThompson discovered the free electron by his research into cathode rays in 1897. He also discovered that ions and electrons are the charge carriers in electrical discharges in gases. 1906 Nobel Prize for Physics.
Tinbergen, Nikolaas The Netherlands1907-1988Zoology MedicineInvestigated animal behavior (especially fish and insects) and humans (childhood autism). Wrote textbooks (e.g. The Study of Instinct) on behaviorism. Awarded the 1973 Nobel Prize for Physiology and Medicine.
Tyndall, John
Great Britain1820-1893PhysicsStuded diamagnetism and made discoveries about infrared radiation and the physical properties of air. He also published books about experimental physics, was professor of physics at the Royal Institution of Great Britain, London, England and a notable mountaineer!
Van de Graaf, Robert USA1901-1967PhysicsDeveloped the eponymous Van de Graaf generator from 1931-33 which was able to generate millions of volts, and used it to accelerate charged particles.
Vesalius, Andreas Belgium1515-1564MedicineVesalius conducted dissections as a student already and by the age of 23 was a professor of surgery. He wrote seven books about the anatomy of the human body and was later also the personal physician of Emperor Charles V of Spain. He belongs to the most famous doctors and physicians in the Middle Ages.
Vieta, Francois France1540-1603MathematicsVieta introduced letters, fraction bars, the root sign and parentheses into mathematics in order to simplify calculations and make formulas more understandable. Thomas Harriot (1560-1621) replaced Vieta’s large letters with small ones, thus founding modern algebraic notation.
Volta, Alessandro Italy1745-1827PhysicsBuilt on Luigi Galvani’s (1737-1798) discovery of the electric current and thereby discovered the electrolysis of water. Among others, Volta invented the battery (1800), an ampere meter and the “voltaic pile” (of copper and zinc).
Watt, James Great Britain1736-1819PhysicsPerfected the efficiency of steam engines by developing new capacitors and the use of connecting rods. James Watt invented “Watt’s parallelogram” and a land survey telescope among other things.
Weierstraß, Karl Germany1815-1897MathematicsWeierstrass made important discoveries for the further development of the general function theory, number theory, and power series. His main work, however, dealt with the proper foundation of analysis (e.g. in the treatment of infinite products). He also coined the term uniform convergence (Weierstrass criterion).
Young, Thomas Great Britain1773-1829Physics MedicineGifted language and all-round genius (he could already read at 2 and spoke 10 languages fluently) who researched color theory, light waves, the tides, the statics and technology, deciphered Egyptian hieroglyphics (including the three scripts of the famous “Rosetta Stone”).
