Francis William Aston won the Nobel Prize in Chemistry for discovering isotopes by conducting mass spectrograph of isotopes. He conducted this research in a large amount of non-radioactive elements. He is also remembered for his whole-number rule.
Gerhard Herzberg was born on the 25th December, 1904, in Hamburg, Germany. A pioneer in both chemistry and physical chemistry, he won the Nobel Prize in Chemistry in 1971. The asteroid 3316 Herzberg too is named after him.
Carl Bosch was born on 27th August, 1874 in Cologne, Germany. He was a German chemist and engineer. Carl won the Nobel Prize in chemistry in 1931 for his contribution in the introduction of high pressure chemistry. The asteroid- 7414 Bosch was named after him in his honour.
Francois Auguste Victor Grignard and Paul Sabatier were joint Noble Laureates for chemistry in the year 1912. They were both French chemists who started their careers in different fields, mathematics and physics, but made respectable contributions to the field of chemistry later in their life.
Frederic Joliot-Curie and Irene Joliot-Curie were both French scientists. Husband and wife, they were jointly awarded Nobel laureates in 1935 for their joint discovery of new radioactive isotopes which they prepared artificially. They are also known for their contribution towards the discovery of the neutron.
