⏹ Coddington, Henry Coddington,

English mathematician (1800 - 1845)
Coddington learned in Cambridge and is famous for suggesting the use of a lens that bears his name, a Corrington lens made in the shape of a ball with engraved gutter on its larger circumference, in order to remove the distortion caused by the side parts as a result of the spherical aberration of light, and although Coddington made this lens in 1830, Brewster It was proposed to use such a lens for the same purpose in minarets (lighthouses) ten years before this date.

⏹ Kurchatov, Igor Vasi Levitch

Soviet physicist (1903-1960)
Kurchatov was educated in Soviet institutions. Then he was appointed director of nuclear physics at the Lenin Institute and then at the Soviet Atomic Institute. He did important research on neutron interactions.
Kurchatov was the guiding figure in making the first Soviet atomic bomb in 1949, as well as the first hydrogen bomb in 1953. He received the Stalin Prize and high scientific titles. He also became a member of the Supreme Soviet in 1949.

⏹ Courtois, Bernard. Bernard Courtois ,

French chemist (1777 - 1838)
Courtois studied chemistry at Ecole Polytechnic, then worked as a pharmacist in a military hospital, then practiced soap making, following in his father's footsteps. However, he did not recover financially from that and spent his life in poverty despite receiving a grant from the state as a result of his discovery of iodine (see Coindet, the Swiss doctor who used iodine in treatment). Courtois discovered iodine in the product of filtering the ashes of some seaweeds, such as rhodominia and laminaria. Gay-Lussac published his results at the same time as Courtois, which sparked controversy over who had the honor of discovery.

⏹ Curtius, Theodore Curtius,

German organic chemist (1857 - 1928)
Curtius taught chemistry in Heidelberg. He made several important achievements in the field of synthetic chemistry, especially his discovery of Na H4) which is a silver agent that returns a reference (reducer) that can transfer hydrazine, gold and platinum from solutions of their salts to the elemental state.
He also discovered tetrazine derivatives, and there is an organic chemical conversion alternative to the Hofmann transformation known as the Curtius transformation.

Cornan, Andre Frederick
Cournand, André Frederic

French-American doctor (1895 - )
Cornan was educated at the Sorbonne in Paris, then worked as a military doctor and won the «Cross of War, in the First World War - after that he emigrated to America.
Cornan participated with Richards and other researchers in research on circulatory disorders at Columbia University, and this team of scientists was able to improve the method of studying the internal vessels and the heart by inserting tubes in them. This was one of the inventions of the German doctor Forsman. The three scientists: Cornan, Richards, and Frosman shared the Nobel Prize for Medicine in 1956.

⏹ Kornberg, Arthur

British biochemist ( 1918 - )
Kornberg occupies the position of Professor of Biochemistry at the University of Oxford He shared with Ochoa the Nobel Prize for Physiology and Medicine in 1959 (see Ochoa, Severo, for his important research and studies on the synthesis of Ribonucleic and Deoxirbonucleic acids, which are usually found in carrier chromosomes). of genetic traits in organisms.
