Birger Dahlerus

Johan Birger Essen Dahlerus (6 February 1891, Stockholm – 8 March 1957, Stockholm) was a Swedish businessman, amateur diplomat and friend of Hermann Göring. He attempted through diplomatic channels to prevent the Second World War.

His futile diplomatic efforts during the days preceding the German invasion of Poland in 1939 are sometimes called the Dahlerus Mission. Provided by Wikipedia
