Becquerel Antoine Henry (Fr) 15/12/1852 to 25/8/1908 Nobel Prize in physics 1903 He was researching fluorescence,, glowing in darkness, In Uranium salts after exposure to light. On his desk he had a photographic plate for X ray photography. It was well wrapped with black paper to prevent exposure. He left a uranium sample on this parcel probably as a paper weight. Following day he found the plate to be fogged as if light had entered. He correctly concluded that some kind of rays had come from the sample. This phenomenon was later named as RADIOACTIVITYY by his most distinguished pupil Marie Curie.
"In 1913, he passed on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus. By introducing conceptions borrowed from the Quantum Theory as established by Planck, ….., he succeeded in working out and presenting a picture of atomic structure that, with later improvements (mainly as a result of Heisenberg's ideas in 1925), still fitly serves as an elucidation of the physical and chemical properties of the elements.” Courtsey Nobel Prize.org.

‘ Father of Evolution”. In his book ‘Origin of Species’ he supplied the necessary evidence in a very convincing manner to support the theory that species change with time and among them there is a struggle and the fittest survive. In modern classical biology the classification of organisms is based on his ideas.
Cafepress Poster Received the Nobel Prize for the explanation of the “photo electric effect” He is considered as the Greatest Physicist after Galileo and Newton. His notable achievement is the popular equation E = mc2 on which the Atomic bomb was based. (Please go to… Albert Einstein.)
