Bohr was a Danish physicist who was among the first to recognize the importance of an element’s atomic number. He was also the first to apply the quantum theory to atomic and molecular structure, and his concept of the atomic nucleus was a key step in understanding nuclear fission. He won a Nobel Prize for Physics in 1922 for his work on atomic theory. Though he contributed to atomic bomb research during World War II, he later devoted himself to arms control.
