Theoretical physicist (1923–2004), a founding figure of canonical quantum gravity, whose 1966
*Physical Review Letters* paper "Superconductors and Gravitational Drag" (16(24): 1092–1093) first
showed that a time-varying gravitomagnetic field must arise from magnetic flux quantization in
superconductors. Matters to this vault as the uncredited founding precursor of its whole
Li–Torr antigravity claim-family: per a 2010 DIA survey document, [[entity-ning-li|Li]] and
[[entity-douglas-torr|Torr]]'s entire 1991–1994 gravitomagnetic-superconductor program (via an
intermediate 1983 modification by O. K. Ross) is an extension of DeWitt's earlier result into a claim
strong enough to eventually draw formal rebuttal.
