<(1915--1950)>

Werner Heisenburg **




 * 1901-1976

**Discovery: 1925 Nobel Prize Recipient: 1932


 * In 1924 through 1925, Heisenburg worked with Niels Bohr, at the University of Copenhagen. A year later he became the Lecturer in Theoretical Physics at the University of Copenhagen under Niels Bohr. Then, in 1927, when he was only 26 years old, he was appointed Professor of Theoretical Physics at the University of Leipzig. He was then asked, in 1929 to go on a lecture tour to the United States, Japan, and India. In 1925, Heisenburg discovered the theory of quantum mechanics and was published within this year. He was only 23 years old during this time. This theory and the applications that resulted of this discovery were allotropic forms of hydrogen. Then in 1932, he was awarded the Nobel Prize for Physics! This theory was based mostly on what could be observed, which was the radiation emitted by the atom.**

1887-1961
 * __ __Erwin Schrodinger__ __**

Discovery: 1926 Nobel Prize Recipient: 1933 Erwin Schrödinger was born on August 12, 1887, in Vienna. In 1898 he attended the Arkademisches school.And Between 1906 and 1910 Schrödinger studied in Vienna under Franz Exne and Hasenohrl. In 1911, Schrödinger became an assistant to Exner. In 1926 Shrodinger came up with the Shrodinger equation which is an equation that describes how the quantum state of a physical system changes in time. It is as important to quantum mechanics as Newton's Laws are to modern mechanics.

__James Chadwick__

1891-1974
 * Discovery**: 1932
 * Nobel Prize Recipient**: 1935

In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons elementary particles devoid of any electrical charge. In contrast with the helium nuclei alpha rays which are charged, and therefore repelled by the considerable electrical forces present in the nuclei of heavy atoms, this new tool in atomic disintegration need not overcome any electric barrier and is capable of penetrating and splitting the nuclei of even the heaviest elements.
