Robert Boyle publishes "Boyle's Law," which states that the volume of a gas is inversely proportional to its pressure. Boyle was deeply religious, and promoted Christianity.
Henry Cavendish experimented with metals and acids to produce "inflammable air," or hydrogen, and "fixed air," or carbon dioxide.
Humphry Davy isolates a variety of elements including sodium and potassium. He is also known for his pioneering work in the field of electrochemistry. Davy was popular among a female following.
John Dalton is best known for his proposition of modern atomic theory, his law of partial pressures, and his research in colorblindness.
Amedeo Avogadro determines that under the same conditions of temperature and pressure, equal volumes of equal gasses contain equal number of molecules. The number of molecules in one gram of a substance is defined by the number 6.0221409×10^23, called Avogadro's number. Avogadro graduated college at age 16.
Robert Bunsen investigates the light spectrum emitted by heated elements. Bunsen went blind in his right eye due to a cacodyl explosion.
Henri Becquerel wins the Nobel Prize in Physics for discovering radioactivity while working with X-rays. There are craters on the Moon and Mars named after Becquerel.
Niels Bohr wins the Nobel Prize in physics for his model of the atom. "An expert is a person who has made all the mistakes that can be made in a very narrow field." -Niels Bohr
Otto Hahn wins the Nobel Prize in Chemistry for discovering nuclear fission. Hahn is considered the father of nuclear chemistry.
Marie and Pierre Curie win the Nobel Prize in Physics for their discovery of radium and polonium. Marie went on to also win a Prize in Chemistry. Marie Curie was the first woman to win a Nobel Prize, and the only person to win two Nobel Prizes.
Charles Martin Hall develops the electrolytic method of producing commercial aluminum while at Oberlin College. His system lowered the price of aluminum to 18 cents per pound.
Irene and Frederic Joliet-Curie win the Nobel Prize in chemistry for discovering and isolating new radioactive isotopes. Irene was the daughter of Marie and Pierre Curie.
Antoine Lavoisier discovers oxygen's role in combustion, opposing to phlogiston theory. Lavoisier also named oxygen and hydrogen, and is considered the father of modern chemistry.
Dimitri Mendeleev publishes the periodic table that is used today, predicting the existence of many undiscovered elements. Mendeleev was a native of Siberia.
Lise Meitner works with Otto Hahn to discover nuclear fission, although Meitner does not receive the Nobel Prize with Hahn.
Henry Moseley discovers the importance of the atom number of an element and its relationship to the element's identity. Moseley correctly predicted four new elements.
Joseph Priestley discovers oxygen and isolates it in its gaseous state. Priestley was also a clergyman.
Wilhelm Roentgen wins the Nobel Prize in physics for the discovery of X-rays. Element number 111, roentgenium, is named after him.
Ernest Rutherford wins the Nobel Prize in Chemistry for his discoveries of radiation and the phenomenon of radioactive decay. Element 104, rutherfordium, is named after him.
Carl Wilhelm Scheele identifies a number of new elements including chlorine, molybdenum, and barium. He is also credited with the discovery of oxygen, although Joseph Priestly published his findings first.
Glenn Seaborg discovers elements americium through nobelium (95–102,) and seaborgium (106) named after him.
