Here’s our alphabetical list of the most popular chemists, or contributors to chemistry, on the Famous Scientists website, ordered by surname.
Amedeo Avogadro 1776 – 1856.The first scientist to realize that elements could exist in the form of molecules rather than as individual atoms; originator of Avogadro’s law.
Jacob Berzelius 1779 – 1848.A founder of modern chemistry: the first person to measure accurate atomic weights for the chemical elements; discovered three elements: cerium, thorium, and selenium; devised the modern symbols for elements; described how chemical bonds form by electrostatic attraction.
Niels Bohr 1885 – 1962.Founded quantum mechanics when he remodeled the atom so electrons occupied ‘allowed’ orbits around the nucleus while all other orbits were forbidden; architect of the Copenhagen interpretation of quantum mechanics.
Robert Boyle 1627 – 1691. Transformed chemistry from a field bogged down in alchemy and mysticism into one based on measurement. He defined elements, compounds, and mixtures; and he discovered the first gas law – Boyle’s Law.
Lawrence Bragg 1890 – 1971. Discovered how to locate the positions of atoms in solids using X-ray diffraction, enabling scientists to build 3D models the atomic arrangements in solids. The discovery was arguably the most significant experimental breakthrough of twentieth century science.
Georg Brandt 1694 – 1768.The first named person in history to discover a new metal – cobalt; was one of the first scientists to condemn alchemy, publicly demonstrating tricks used by alchemists to make people think they could make gold.
Robert Bunsen 1811 – 1899.Discovered cesium and rubidium; discovered the antidote to arsenic poisoning; invented the zinc-carbon battery and flash photography; discovered how geysers operate.
Marie Curie 1867 – 1934.Codiscovered the chemical elements radium and polonium; made numerous pioneering contributions to the study of radioactive elements; carried out the first research into the treatment of tumors with radiation.
John Dalton 1766 – 1844.Dalton’s Atomic Theory is the basis of chemistry; discovered Gay-Lussac’s Law relating gases’ temperature, volume, and pressure; discovered the law of partial gas pressures.
Empedocles c. 490 BC – c 430 BC.An ancient theory of natural selection; mass conservation; and the four elements which are now often misattributed to Aristotle.
Michael Faraday 1791 – 1867.Discovered electromagnetic induction; devised Faraday’s laws of electrolysis; discovered the first experimental link between light and magnetism; carried out the first room-temperature liquefaction of a gas; discovered benzene.
Rosalind Franklin 1920 – 1958.Provided much of the experimental data used to establish the structure of DNA, and discovered that DNA can exist in two forms. Established that coal acts as a molecular sieve.
Willard Gibbs 1839 – 1903.Gibbs invented vector analysis and founded the sciences of modern statistical mechanics and chemical thermodynamics.
Fred Hoyle 1915 – 2001.Proved that most of the naturally occurring elements in the periodic table were made inside stars and distributed through space by supernova explosions; coined the phrase ‘Big Bang’ while strenuously denying that there had ever been one; argued for an expanding Steady State universe with no beginning or end.
Irene Joliot-Curie 1897 – 1956.Co-discovered how to convert stable chemical elements into ‘designer’ radioactive elements; these have saved millions of lives and are used in tens of millions of medical procedures every year.
Stephanie Kwolek 1923 – 2014.Invented kevlar, the incredibly strong plastic used in applications ranging from body armor to tennis racquet strings.
Antoine Lavoisier 1743 – 1794.A founder of modern chemistry; discovered oxygen’s role in combustion and respiration; discovered that water is a compound of hydrogen and oxygen; proved that diamond and charcoal are different forms of the same element, which he named carbon.
Ernest Lawrence 1901 – 1958.Invented the cyclotron, used by scientific teams in his laboratories to discover large numbers of new chemical elements and isotopes. Founded big science.
Jane Marcet 1769 – 1858.Author of Conversations on Chemistry, a unique textbook for its time written for people with little formal education, such as girls and the poor. The book inspired Michael Faraday to overcome his poor origins to become a great scientist.
Dmitri Mendeleev 1834 – 1907.Discovered the periodic table in a dream. Utilized the organizing principles of the periodic table to correctly predict the existence and properties of six new chemical elements.
Henry Moseley 1887 – 1915.Proved that every element’s identity is uniquely determined by its number of protons, establishing this is the true organizing principle of the periodic table; correctly predicted the existence of four new chemical elements; invented the atomic battery.
Alfred Nobel 1833 – 1896.Invented dynamite, the blasting cap, gelignite, and ballistite; grew enormously wealthy manufacturing explosives; used his wealth to bequeath annual prizes in science, literature, and peace.
Hans Christian Oersted 1777 – 1851.Discovered electromagnetism when he found that electric current caused a nearby magnetic needle to move; discovered piperine and achieved the first isolation of the element aluminum.
Louis Pasteur 1822 – 1895.The father of modern microbiology; transformed chemistry and biology with his discovery of mirror-image molecules; discovered anaerobic bacteria; established the germ theory of disease; invented food preservation by pasteurization.
Linus Pauling 1901 – 1994.Maverick giant of chemistry; formulated valence bond theory and electronegativity; founded the fields of quantum chemistry, molecular biology, and molecular genetics. Discovered the alpha-helix structure of proteins; proved that sickle-cell anemia is a molecular disease.
Marguerite Perey 1909 – 1975.Discovered francium, the last ever chemical element found naturally. All elements since have been produced artificially.
C. V. Raman 1888 – 1970.Discovered that light can donate a small amount of energy to a molecule, changing the light’s color and causing the molecule to vibrate. The color change acts as a ‘fingerprint’ for the molecule that can be used to identify molecules and detect diseases such as cancer.
William Ramsay 1852 – 1916.Predicted the existence of the noble gases and either discovered or was first to isolate every member of the group; created the world’s very first neon light.
Ernest Rutherford 1871 – 1937.The father of nuclear chemistry and nuclear physics; discovered and named the atomic nucleus, the proton, the alpha particle, and the beta particle; discovered the concept of nuclear half-lives; achieved the first laboratory transformation of one element into another.
Glenn Seaborg 1912 to 1999.Took part in the discovery of ten of the periodic table’s chemical elements. His work on the electronic structure of elements led to the periodic table being rewritten.
J. J. Thomson 1856 – 1940.Discovered the electron; invented one of the most powerful tools in analytical chemistry – the mass spectrometer; obtained the first evidence for isotopes of stable elements.
Harold Urey 1893 – 1981.Discovered deuterium; showed how isotope ratios in rocks reveal past Earth climates; founded modern planetary science; the Miller-Urey experiment demonstrated that electrically sparking simple gases produces amino acids – the building blocks of life.
Alessandro Volta 1745 – 1827.Pioneer of electrical science; invented the electric battery; wrote the first electromotive series; isolated methane for the first time; discovered a methane-air mixture could be exploded using an electric spark – the basis of the internal combustion engine.
Sergei Winogradsky 1856 – 1953.Founded microbial ecology; discovered chemosynthetic life forms which obtain energy from chemical reactions rather than from sunlight; discovered nitrogen-fixing bacteria in soil that make nitrates available to green plants.
