1915-1950+(Smedile.Enrique)





Niels Bohr Oct 7 1885 – Nov 18 1962 Danish Year of Discovery: 1921

He studied in the university of Copenhagen. When the Royal Danish Academy of Sciences and Letter offered a gold medal, he started researching and experimenting with surface tension. When he won the prize it led Bohr to drop philosophy and start studying physics. He studied together with Rutherford and his theories. when Bohr came out with his atomic structure he introduces electrons travelling in orbits. this came to explain and start to explain the quantum theory.

Contributions for the understanding of atomic structure and quantum mechanics, received noble prize for physics in 1922. Manhattan project. Worked top secrete in New Mexico for the Manhattan project. Major roll but will not be able to know because of top secret reasons.

Walter H. Brattain **February 10, 1902- October 13, 1987**
 * Country of origin: Born in China, raised in the USA**
 * Year of discovery: 1929

**

Brattain received his B.S. from Whitman College, was awarded his M.A. from the University of Oregon, and received his PHD from the University of Minnesota. He spent the majority of career working for Bell Laboratories. During WWII Brattain worked on systems to detected submarines under the contract of the National Defense. Following the war, Brattain did his major work on the development of semiconductors. His work on semiconductors allowed many electronics and computers to be made in the modern age.

Erwin Schrödinger August 12, 1887-January 4rth 1961 Country of Origin- Republic of Austria Year of Discovery: 1926

After receiving his chemistry education Erwin spent years devoting himself to Italian paintings. Later, he became a botanist and published many papers in the field. During World War one he became an artillery officer. He wrote many papers on the problem of unifying gravitation and electromagnetism, which inspired Einstein. In 1926 Schrodinger’s major contribution to chemistry was his equation the “Schrödinger Equation.” This equation showed that things in matter moved like waves. []

 * Cecil Frank Powell **
 * December 5, 1903- August 9, 1969 **
 * Country of Origin: England **
 * Year of Discovery: 1947

** Powell was the son of a gunsmith in Kent. He was earning scholarships to school as early as age 11. He graduated from Sidney Sussex College in Cambridge at the top of his class. Powell then worked in the Cavendish Laboratories where he worked with Rutherford. He is known for the scattering and disintegration process to research cosmic radiation. This lead him to discover heavy mesons and their properties.
