The title and intro read: GRAVITATIONAL FIELD OF A SPINNING MASS AS AN EXAMPLE OF ALGEBRAICALLY SPECIAL METRICS Roy P. Kerr* University of Texas, Austin, Texas and Aerospace Research Laboratories, Wright- Patterson Air Force Base, Ohio (Received 26 July 1963) Goldberg and Sachs' have proved that the alge-braically special solutions of Einstein's empty-space field equations are characterized by the existence of a geodesic and shear-free ray con-gruence, ku• Among these spaces are the plane-fronted waves and the Robinson-Trautman metrics? for which the congruence has nonvanishing diver-gence, but is hypersurface orthogonal.

Happy Rotating Black Hole Day!
Roy Kerr submitted his breakthrough paper describing the spacetime around a rotating black hole #OTD in 1963.
Physicists had been searching for decades for this solution to the field equations of Einstein's theory of general relativity.
