One of the scientists of the 20th century, Niels Henrik David Bohr was the first to apply the quantum theory, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. He was a major contributor to the development of quantum mechanics and atomic physics. His work on atomic theory was recognized by the Nobel Prize Of Physics in 1922. Niels Bohr was born in Copenhagen on October 7th, 1885. Niels father, Christian Bohr was a professor of physiology at the University of Copenhagen and was known for his work on the physical and chemical aspects of respiration. Niels mother, Ellen Adler Bohr came from a Jewish family. Bohr's scientific interests and abilities showed early in his life. Niels's younger brother, Harald had became a brilliant mathematician. Niels Bohr went to the University of Copenhagen and won a gold medal from the Royal Danish Academy of Sciences and Letters for his analysis of and precise experiments on the vibrations of water jets as a way of determining surface tension. Also In 1911 he received his doctorate for a thesis on the electron theory of metals. Niels then went to England, intending to continue this work with Sir. J.J Thomson at Cambridge. Sir. J.J Thomson never showed much interest in Niels ideas on electrons in metals, however he had worked on this subject in the earlier years. Niels moved to Manchester in March 1912 and then joined Ernets Rutherford’s group studying the structure of the atom. In Manchester, Niels worked on the theoretical implications of the nuclear model of the atom proposed by Rutherford and known as the “Rutherford atomic model”. Niels was among the first to see the importance of the atomic number, which shows the position of an element in the periodic table and is equal to the number of natural units of electric charge on the nuclei of its atoms.
