Jons Jacob Berzelius
Died August 7, 1848
Berzelius began his career as a physician but his researches in physical chemistry were of lasting significance in the development of the subject. He is especially noted for his determination of atomic weights; his experiments led to a more complete depiction of the principles of stoichiometry, or the field of chemical combining proportions. In 1803 Berzelius demonstrated the power of an electrochemical cell to decompose chemicals into pairs of electrically opposite constitue -
Dimitri Mandeleev
Died Febuary 2 1907
Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of elements yet to be discovered. -
Joseph John Thompson
Died 30 1940 -
Marie Curie
Died July 4, 1934
Her achievements included a theory of radioactivity (a term that she coined]), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world's first studies were conducted into the treatment of neoplasms, using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. -
Ernst Rutherford
Died October 19, 1937
Ernest Rutherford, 1st Baron Rutherford of Nelson, OM FRS was a New Zealand-born physicist and chemist who became known as the father of nuclear physics. He is considered the greatest experimentalist since Michael Faraday. -
Niels Bohr
Died Nov 18, 1962 -
Erwin Schrodinger
Died January 4, 1961
Austrian physicist who developed a number of fundamental results in the field of quantum theory, which formed the basis of wave mechanics: he formulated the wave equation (stationary and time-dependent Schrödinger equation) and revealed the identity of his development of the formalism and matrix mechanics. -
Werne Hiesenberg
Died Febuary 1, 1976
Werner Karl Heisenberg (5 December 1901 – 1 February 1976) was a German theoretical physicist and one of the key creators of quantum mechanics. He published his work in 1925 in a breakthrough paper. In the subsequent series of papers with Max Born and Pascual Jordan, during the same year, this matrix formulation of quantum mechanics was substantially elaborated. In 1927 he published his uncertainty principle, upon which he built his philosophy and for which he is best known. -
