'''John Archibald Wheeler''' (9 July 1911 - 13 April 2008) was an American theoretical physicist whose work connected nuclear physics, general relativity, quantum foundations, and quantum gravity. He helped popularize the term "black hole" and supervised or influenced major figures in twentieth-century physics, including [[Biography:Richard Feynman|Richard Feynman]] and [[Biography:Hugh Everett III|Hugh Everett III]].<ref>{{cite web |url=https://www.ias.edu/scholars/wheeler |title=John Archibald Wheeler |publisher=Institute for Advanced Study |access-date=20 May 2026}}</ref><br />
<br />
Wheeler worked on nuclear fission, scattering theory, relativity, geometrodynamics, and the conceptual foundations of quantum mechanics. His delayed-choice thought experiments became important in discussions of measurement, observation, and the meaning of quantum events.<br />
<br />
== Quantum gravity and foundations ==<br />
Wheeler's name is attached to the Wheeler-DeWitt equation, a central formal expression in canonical quantum gravity. It attempts to describe a quantum state of geometry and matter without relying on an external time parameter, linking [[Physics:Quantum curved spacetime|curved spacetime]] with [[Physics:Quantum quantum gravity|quantum gravity]].<br />
<br />
His influence also appears in quantum information and interpretation. Wheeler's phrase "it from bit" captured his interest in the relationship between physical reality, information, and observation.<br />
