International Society on General Relativity and Gravitation
The International Society on General Relativity and Gravitation is a learned society with the goal to promote research on gravitation, in particular Albert Einstein's theory of general relativity. To that end, it encourages communication between relativity researchers, in particular by organizing the triennial international GR conferences, and publishing the journal General Relativity and Gravitation. The society also serves as the Affiliated Commission 2 (AC.2) of the International Union of Pure and Applied Physics.
The society's president is always a prominent relativity researcher. In the past, the office has been held by Christian Møller (1971-74), Nathan Rosen (1974-77), Peter Bergmann (1977-80), Yvonne Choquet-Bruhat (1980-83), Dennis Sciama (1983-86), Ezra Ted Newman (1986-89), George Ellis (1989-92), Roger Penrose (1992-95), Jürgen Ehlers (1995-8), Werner Israel (1998-2001), Robert Wald (2001-4) and Clifford Will (2004-7). The current president is Abhay Ashtekar.
The Society's archive is housed in the Max Planck Institute for Gravitational Physics in Potsdam, Germany.
