Person: Gruenberg, Karl Walter
Karl Gruenberg was an Austrian mathematician who worked in finite group theory.
Mathematical Profile (Excerpt):
 The Kindertransport allowed Karl to be sent to England in March of 1939 but life was not easy for the ten year old German speaking boy.
 At first Karl attended Shaftesbury Grammar School in Dorset.
 Soon Gruenberg flourished, achieving excellent school grades, and his broad international based views meant he became very happy with his new life.
 By this time Gruenberg had become a British citizen, all the procedures being completed by 1948.
 Before the award of his doctorate Gruenberg had published a number of papers such as Some theorems on commutative matrices (1951), A note on a theorem of Burnside (1952), Two theorems on Engel groups (1953), and Commutators in associative rings (1953).
 Back in England after his two years in the United States, Gruenberg returned to Queen Mary College where he was appointed as a Lecturer in Mathematics.
 Gruenberg's first research topic led him to a study of Engel groups.
 Results of many mathematicians such as Burnside, Thompson, Serre, Mac Lane, Magnus, Fox, Iwasawa, Golod, Safarevic, Roquette, and Gaschütz are discussed, but large parts of the work was based on results by Gruenberg himself.
 In addition to these research level texts, Gruenberg also published an undergraduate level text (written jointly with A J Weir) Linear geometry.
 Gruenberg was always encouraging to his mathematical colleagues, and he showed particular kindness to those embarking on a mathematical career.
 Kurt Hirsch and Karl Gruenberg sat in the front row and both made encouraging and helpful comments to me after my talk.
Born 3 June 1928, Vienna, Austria. Died 10 October 2007, London, England.
