Person: Levin (2), Frank
Frank Levin was an American mathematician who worked mainly in infinite group theory.
Mathematical Profile (Excerpt):
 It turned out the chief had given Frank the wrong data to begin with.
 On his frequent trips to Belgrade, Frank took the opportunity of stopping in London, where he worked with me.
 Frank was one of those few mathematicians who never gave up working on mathematics when he retired, and indeed, he was still working on a paper with Narain Gupta on the fateful day when he had a stroke.
 Frank was a very quiet, modest man.
 Frank did not swear, mainly because he had no violence in his makeup.
 He did not even curse when he told me about a friend who had used Frank to guarantee a loan, and then decamped leaving the debt to Frank.
Born 19 June 1927, Dayton, Ohio, USA. Died 2 October 2011, Swansea, Wales.
