Born into a business family, he was introduced to the method of studying cells by his pathologist uncle.
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.
13 Georg Cantor
Austrian physicist and philosopher, Ludwig Boltzmann, played a key role in the development of statistical mechanics. As a young man, he was appointed a professor of mathematical physics at the University of Graz. He worked extensively with other physicists over the course of his brilliant academic career. He suffered from bipolar disorder and died by suicide in 1906.
15 Piers Corbyn
16 Steven Chu
18 Ed Boon
19 Nick Bostrom
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.
22 Gerald Bull
Gerald Vincent Bull was a Canadian artillery expert, known for designing Project Babylon supergun for the Government of Iraq. His idea was to do away with the conventional rockets by firing satellites into orbit from a 156m-long barrel embedded inside a hill. However, his assassination within two years of the start of the project put an end to it.
Marcello Malpighi was forced to take up grammatical studies by his father but later earned doctorates in philosophy and medicine. Malpighi revolutionized medical science by discovering things such as taste buds, red blood cells, and the pulmonary and capillary network connecting veins and arteries. Many physiological features bear his name.
Alexander Graham Bell was a scientist, inventor, and engineer. He is credited with inventing the first functional telephone. He is also credited with co-founding America's major telephone company AT&T, which has been going strong since 1885. Bell's later life was marked by his groundbreaking work in aeronautics, hydrofoils, and optical telecommunications. He was also an ardent supporter of compulsory sterilization.
Frédéric Joliot-Curie was a French physicist whose discovery of artificial radioactivity earned him the 1935 Nobel Prize in Chemistry, which was jointly awarded to Frédéric and his wife Irène Joliot-Curie. Along with his wife, Frédéric is credited with founding the Orsay Faculty of Sciences, a physics and mathematics school within Paris-Saclay University. He had also won the Stalin Peace Prize.
The son of renowned astronomer William Herschel, John Herschel was educated at Eton and Cambridge and grew up to be a polymath. Apart from contributing to the field of photography, he was known for cataloguing and naming stars and satellites. He briefly also served as the Master of the Royal Mint.
30 Brian Cox
Brian Cox is an English physicist and former musician. He has presented numerous science programs for BBC radio and TV, especially the Wonders of... series. He is also the author of several popular science books. He has been lauded for his efforts to publicize science and was awarded the British Association's Lord Kelvin Award in 2006.
Born into an affluent Jewish Brazilian family, Eduardo Saverin co-founded Facebook with his Harvard roommate Mark Zuckerberg and others in 2004. He was later involved in a lawsuit against Zuckerberg. He also renounced his U.S. citizenship and moved to Singapore, which some believe was his excuse to avoid paying taxes.
33 Jef Raskin
British philosopher and mathematician Frank P. Ramsey was the son of a famed mathematician and later laid down the Ramsey theory of mathematical logic. The Cambridge alumnus also translated Ludwig Wittgenstein’s Tractatus Logico-Philosophicus but died at age 26, probably due to a liver infection he contracted while swimming.
35 George Gamow
Born to school teacher parents, Ukrainian-American physicist George Gamow grew up to be a pioneer of the big-bang theory. His other contributions include the liquid-drop model of atomic nuclei and his research on DNA. Apart from various science textbooks, he also wrote the popular Mr. Tompkins series of physics books.
36 Kurt Tank
