Early 20th century · Theoretical physics / Philosophy of science
Niels Bohr (1885-1962) was a Danish physicist who made foundational contributions to atomic theory and quantum mechanics, for which he received the Nobel Prize in Physics in 1922. He founded the Institute of Theoretical Physics in Copenhagen, which became a central hub for quantum research, and developed the Copenhagen interpretation, which emphasizes the role of observation and probability. Bohr also contributed to the philosophy of science, introducing concepts like complementarity to address the paradoxes of quantum phenomena.
