Georg Kreisel FRS (September 15, 1923 – March 1, 2015)[1] was an Austrian-born mathematical logician who studied and worked in the United Kingdom and America.
He studied mathematics at Trinity College, Cambridge, and then, during World War II, worked on military subjects.
Kreisel never took a Ph.D., though much later, in 1962, he was awarded the Cambridge degree of Sc.D., a `higher doctorate' given on the basis of published research.
Peter Conradi reports that Murdoch transcribed Kreisel's letters into her journals over the next fifty years.
According to Conradi, "For half a century she nonetheless records variously Kreisel's brilliance, wit and sheer 'dotty' solipsistic strangeness, his amoralism, cruelty, ambiguous vanity and obscenity."
He wrote several biographies of mathematicians including Kurt Gödel,[12] Bertrand Russell[13] and Luitzen Egbertus Jan Brouwer.
