Michael Faraday was an English scientist known for his contribution to the study of electrochemistry and electromagnetism. Considered one of the most influential scientists ever, Faraday's inventions of electromagnetic rotary devices established the basis for electric motor technology. His research also helped understand the concept of the electromagnetic field. Ernest Rutherford called him one of the greatest scientific discoverers ever.
Alfred Nobel was a Swedish chemist, engineer, and inventor. A prolific inventor, he held 355 different patents. Most popular as the inventor of dynamite, he was concerned with how he would be remembered after his death and bequeathed his fortune to the Nobel Prize institution. A wide traveler, he was proficient in several languages.
New Zealand physicist Ernest Rutherford is remembered as the father of nuclear physics. His discovery of radioactive half-life and of radon, and his differentiation of alpha and beta radiation, won him the Nobel Prize in Chemistry in 1908. Element 104 was named rutherfordium in his honor.
John Dalton was an English chemist, physicist, and meteorologist most famous for introducing the atomic theory into chemistry. He also contributed a lot to the study of color blindness, sometimes referred to as Daltonism in his honor. He was the first scientist to refer to the smallest particle of matter as an “atom.” He was a Quaker and lived modestly.
Antoine Lavoisier was a French chemist and nobleman. He played a crucial role during the chemical revolution of the 18th-century. Widely regarded as the father of modern chemistry, Lavoisier had a major influence on the history of biology as well as the history of chemistry. He also helped build the metric system.
Only person to win two unshared Nobel Prizes, Linus Carl Pauling was an American theoretical physical chemist, who received the 1954 Nobel Prize in Chemistry for his work on nature of chemical bond and 1962 Nobel Prize for Peace for his efforts to stop nuclear weapon testing. Also a prolific writer and educator, he has published 1,200 books and papers.
12 Fritz Haber
Fritz Haber was a German chemist who was honored with the prestigious Nobel Prize in Chemistry for inventing the Haber-Bosch process. The process is used widely to synthesize ammonia from hydrogen gas and nitrogen gas. For his pioneering work in weaponizing poisonous gases like chlorine during World War I, Haber is referred to as the father of chemical warfare.
13 Robert Boyle
Robert Boyle was an Anglo-Irish chemist, natural philosopher, inventor, and physicist. Regarded as the first modern chemist, Boyle is often counted among the founders of modern chemistry. One of the pioneers of the scientific method, Robert Boyle is also remembered for his books, including The Sceptical Chymist, which is viewed as a keystone book in chemistry.
14 Humphry Davy
Best remembered for his invention of the Davy lamp, a safety lamp for miners, Humphry Davy initially aspired to be a doctor but later deviated to chemistry. The Copley Medal winner had co-founded the Zoological Society of London. He also excelled in writing poetry and loved fishing.
Best remembered for his contribution to the chemistry of gases, Joseph Priestley was an English scientist, clergyman, political theorist and educator, who has been credited with discovering oxygen independently, publishing his findings before Carl Wilhelm could. A prolific writer, he has authored 150 works on various subjects including electricity. He also contributed immensely to the advancement of political and religious thoughts.
William Henry Perkin is best remembered for his chance discovery of the dye mauveine, made of aniline purple. He had apparently discovered the dye while attempting to synthesize quinine. The Royal Medal-winning British chemist also studied salicyl alcohol and flavoring agents and synthesized the first artificial perfume.
Henry Moseley was an English physicist best known for his development of Moseley's law in X-ray spectra. He made major contributions to the fields of atomic physics, nuclear physics, and quantum physics. He was working at the University of Oxford when World War I broke out, following which he went to volunteer for the Royal Engineers of the British Army.
Son of a reputed senator and lawyer in Italy, Amedeo Avogadro was himself a qualified lawyer. However, he later delved into research as a mathematical physicist and is best remembered for laying down the Avogadro’s law, contributing to the molecular theory of gases. The Avogadro constant is named after him.
Hans Christian Ørsted was a Danish chemist and physicist. He was the first person to discover that electric currents can be used to create magnetic fields. His discovery was the first relationship found between magnetism and electricity. Oersted, the unit of the auxiliary magnetic field H, is named in his honor.
20 Ahmed Zewail
English natural philosopher, scientist, and a prominent experimental and theoretical physicist and chemist Henry Cavendish is best-remembered for his discovery of hydrogen and his Cavendish experiment. He first recognized that hydrogen, which he termed inflammable air, is a discrete substance which produces water on combustion. He conducted the Cavendish experiment to measure and produce a value for Earth’s density.
22 Otto Hahn
Frederick Sanger remains one of only two people to have won the Nobel Prize twice in the same category. The British biochemist is remembered for his ground-breaking work on nucleic acids and the insulin molecule. The son of a Quaker medical missionary, Sanger, too, grew up believing in Quakerism.
Svante Arrhenius was a Swedish scientist who became the first Swedish person to win a Nobel Prize when he won the Nobel Prize for Chemistry in 1903. Although he was originally a physicist, Arrhenius is widely accepted as a chemist and is best remembered for co-founding physical chemistry. Stockholm University houses the Arrhenius Labs, which is named in his honor.
Dorothy Hodgkin received the 1964 Nobel Prize for mapping the structure of penicillin and Vitamin B12. She is also known for her work on insulin. Beginning her work on structure of an organic compound by using X-ray crystallography as an undergraduate student, she later developed it further and used it to determine the three-dimensional structure of complex organic molecules.
The son of a civil engineer, Nobel Prize-winning Scottish chemist William Ramsay revolutionized science with his pathbreaking discovery of the noble gases, thus forming an entirely new segment of the periodic table. He is also remembered for his long association with UCL. He was knighted for his achievements.
Chemist Robert Bunsen paved the path for spectrum analysis with his discovery that every element emits a light of a particular wavelength. He also co-developed and lent his name to the Bunsen burner. He almost died of arsenic poisoning and lost sight in his right eye in a laboratory explosion.
Known for his pathbreaking Gay-Lussac's Law, French chemist-physicist Joseph Louis Gay-Lussac was also the first, along with his colleague Alexander von Humboldt, to discover that water is composed of one part of oxygen and two parts of hydrogen. His name is one of the 72 that adorn the Eiffel Tower.
Marie Curie and Pierre Curie’s daughter, Irène Joliot-Curie, herself a brilliant scientist, won the 1935 Nobel Prize in Chemistry, along with her husband, Joliot-Curie, for discovering artificial radioactivity. She was also one of the first three female French government members. She tragically died of leukemia caused by exposure to radiation.
Swiss chemist Albert Hofmann was the first known person to synthesize the psychedelic effects of lysergic acid diethylamide (LSD). Interested in science from a young age, he studied chemistry at the University of Zürich. As a chemist, he conducted several significant studies and authored more than 100 scientific articles and books. He was a recipient of the prestigious Scheele Award.
40 Jerry Buss
A pioneer of psychedelic drug synthesis, Alexander Shulgin came to be known as The Godfather of Ecstasy, for reinventing the drug MDMA, or ecstasy, for medical use. The Harvard drop-out, who later studied psychiatry and pharmacology, would often experiment his newly invented drugs on himself, his wife, and his friends.
46 Harold Urey
47 Tu Youyou
Chinese phytochemist and malariologist Tu Youyou is best remembered for her Nobel Prize-winning discovery of the anti-malarial drug qinghaosu, or artemisinin. She is the first Chinese female Nobel laureate. A tuberculosis infection in her younger days had inspired her to step into medicine. She later studied traditional Chinese medicine, too.
