1885 - 1962
Niels Bohr was a Danish physicist born on October 7, 1885, known for his foundational contributions to understanding atomic structure and quantum theory. He proposed the Bohr model of the atom, which introduced the idea of quantized energy levels, and received the Nobel Prize in Physics in 1922. Bohr also played a significant role in the development of quantum mechanics and contributed to discussions on the implications of nuclear weapons during World War II.
