Bohr, Niels (1885-1962) Danish physicist. He is one of the most influential scientists of the twentieth century. He was the founder of atomic quantum theory and the Copenhagen interpretation of quantum physics. His theory

two years later. In 1913 Niels Bohr predicted the emission spectrum for hydrogen with a simple ‘planetary’ model of the atom in which the angular momentum of the orbiting electron , and thus the size of its orbits, are quantized. In
