Which employer did Achilles Papapetrou work for from 1946 to 1948?
Achilles Papapetrou Achille Papapetrou ( ; February 2 , 1907 – August 12 , 1997 ) was a Greek theoretical physicist , who contributed to the general theory of relativity . He is known for the Mathisson–Papapetrou–Dixon equations , the Majumdar–Papapetrou solution , and the Weyl−Lewis−Papapetrou coordinates of gravity theory . He worked on exact solutions of Einsteins field equations and long sought a solution for rotating masses , which , however , were only found by Roy Kerr . Papapetrou was then the first who recognized and jubilantly welcomed Kerrs breakthrough announced at the Texas Symposium on Relativistic Astrophysics , Dallas , December 1963 . Early life and education . Papapetrou was born in Irakleia Serres in Northern Greece ( Macedonia province ) , on February 2 , 1907 . His father was a schoolteacher . During World War I , his family was deported from Serres , but returned at the end of the war . From 1925 , Papapetrou studied mechanical and electrical engineering at the National Technical University of Athens , graduating in 1930 . While a student , he was an assistant in the mathematics department , and he started work as an engineer . Research . His start in physics , in 1934 , was through graduate studies on solid state physics under Paul Peter Ewald enabled through a scholarship , at the Technical University of Stuttgart . While there , he started working with Helmut Hönl , who was instrumental in the development of his interest in theory of relativity . In 1935 , he earned his PhD there , with a dissertation on Investigations on the dendrite growth of crystals , and subsequently returned to the Technical University in Athens as an assistant in electrical engineering . In 1940−1946 , he was professor of physics at the National Technical University of Athens , where he gave seminars on the theory of relativity , and worked in relative isolation during the German occupation of that country . After the end of the war , and in the preamble to the civil war that followed , he was fired from that post for his sympathies with the left-leaning resistance movement . As a result , in 1946 , he moved to the Dublin Institute for Advanced Studies at the invitation of Erwin Schrödinger , with whom he worked on unified field theories . From 1948 on , he worked at the University of Manchester where he was a colleague of Leon Rosenfeld and worked on the equations of motion of GR , as well as the equations of motion of particles with spin in GR . In 1952–1961 he was a researcher at the Research Institute of Mathematics of the National Academy of Sciences in East Berlin , and from 1957 professor at the Humboldt University of Berlin where , among others , Georg Dautcourt and Hans-Jürgen Treder were his pupils . During 1960–61 , he was visiting a group of relativity theorists , including André Lichnerowicz and Yvonne Choquet-Bruhat . From 1962 he was at the Institute Henri Poincaré ( IHP ) in Paris . At the same time , he was research director of CNRS . Among others , he worked on elastic waves in gravitational radiation detectors , shells of matter and their gravitational collapse , the Newman−Penrose formalism and its identities , stationary axially symmetric gravitational fields , and gravitational and electromagnetic radiation fields . In 1975 , he became Director of the IHP Laboratory of Theoretical Physics , and in 1977 he retired , remaining scientifically active . He was a visiting scientist at Princeton ( 1964–65 ) , the University of Vienna ( 1970–71 ) , and Boston University ( 1972 ) . He later took French citizenship . From 1971 on , he was one of the organizing committee members of the international conferences on general relativity and gravitation ( GRG ) . He died in Paris , on August 12 , 1997 .
