John Barbirolli
The Hallé Orchestra, based in Manchester, England, had been famous under the conductor Hamilton Harty.  However, in recent years they had been sharing half their players with the BBC.  This had saved the orchestra in the difficult years when the economy was bad and during the early war years, but the orchestra was not as good as it had been.  Barbirolli was invited to become the conductor of the orchestra, so he moved back to England in 1943.
