||Torbern Olaf (Olof) Bergman (KVO) (b. 20 March 1735) was a Swedish chemist and mineralogist noted for his 1775 Dissertation on Elective Attractions, containing the largest chemical affinity tables ever published. Bergman was the first chemist to use the A, B, C, etc., system of notation for chemical species.
||Martin(us) van Marum (b. 20 March 1750) was a Dutch physician, inventor, scientist and teacher, who studied medicine and philosophy in Groningen. Van Marum introduced modern chemistry in the Netherlands after the theories of Lavoisier, and several scientific applications for general use. He became famous for his demonstrations with instruments, most notable the Large electricity machine, to show statical electricity and chemical experiments while curator for the Teylers Museum.
||1834 – Charles William Eliot, American mathematician and academic (d. 1926)

File:Ernst Schroeder.jpg|link=Ernst Schröder (nonfiction)|1877: Mathematician and logician [[Ernst Schröder (nonfiction)|Ernst Schröder]] systematizes various systems of formal logic in a successful effort to prevent [[crimes against mathematical constants]].


File:Julius Robert Mayer.jpg|link=Julius von Mayer (nonfiction)|1878: Physician and physicist [[Julius von Mayer (nonfiction)|Julius Robert von Mayer]] dies. In 1842, Mayer described the vital chemical process now referred to as oxidation as the primary source of energy for any living creature. His achievements were overlooked and priority for the discovery of the mechanical equivalent of heat was attributed to James Joule in the following year.

||Maud Leonora Menten (b. March 20, 1879) was a Canadian physician-scientist who made significant contributions to enzyme kinetics and histochemistry. Her name is associated with the famous Michaelis–Menten equation in biochemistry. Pic.
||1884 – Philipp Frank, Austrian-American physicist, mathematician, and philosopher (d. 1966)
||Carl Anton Bjerknes (d. 20 March 1903) was a Norwegian mathematician and physicist. Bjerknes' earlier work was in pure mathematics, but he is principally known for his studies in hydrodynamics.

||1922 – The USS Langley is commissioned as the first United States Navy aircraft carrier.
 
||1928 – James P. Gordon, American physicist and engineer (d. 2013) known for his work in the fields of optics and quantum electronics. His contributions include the design, analysis and construction of the first maser in 1954 as a doctoral student at Columbia University under the supervision of C. H. Townes, development of the quantal equivalent of Shannon’s information capacity formula in 1962, development of the theory for the diffusion of atoms in an optical trap (together with A. Ashkin) in 1980, and the discovery of what is now known as the Gordon-Haus effect in soliton transmission, together with H. A. Haus in 1986. Pic.
 
||1933 – Giuseppe Zangara is executed in Florida's electric chair for fatally shooting Anton Cermak in an assassination attempt against President-Elect Franklin D. Roosevelt.
