Professor Large teaches German history at Montana University,and has written extensively on modern German history.The attraction of his analysis is that he's American-Germany never invaded or bombed the USA,so US writers have a more objective viewpoint that their European counterparts.
This is the story of Berlin from the first unification of Germany in 1871 to the second in 1990(and a bit beyond).Thankfully,the section on the Nazi era does not take up most of the book,and recognises that Hitler is not the be-all and end-all of Germany,unlike some writers.Takes in cultural,economic and social history as well as political and military matters,and is very sharp on Berlin's contribution to literature(Alfred Doblin,Erich Kastner,Brecht,on up to Gunter Grass and Peter Schneider).
My favourite part is the compare and contrast chapters on Berlin as a divided city(from 1961 to 1989).His eye for the bizarre similarities as well as expected differences is very acute here,as his great use of examples from youth culture-anti-Vietnam war protestors in the west,punks and skinheads in the east.
Problem is that it's out of print,at least in the UK,so get a second-hand copy now,or get it from the US Amazon website.
