Ivar Kreuger was one of the mighest men in Europe and the world in 1920-1930
He owned share in SKF ball bearings,
Ericsson Swedish match etcetera, totaly he had 400 companies at its peak.
He loaned out money to countries worth of 10 billion dollars in todays money.
That supports that he was murdered:
he had little reasons to make suecide, his family said he felt good and he had big deals going on.
His family and brother claimed it was murder.
He was shot in the heart, normally shot to the brain is the normal suecide method.
He was going make a huge deal become monopoly in Germany with his matches and taking a loan from riksbank to Germany. So things was going well.
Jacob Wallenberg and Hugo Stenbeck was at his apartment in Paris a few days after said that it was worthless, although Jacob wallenberg and his family later became the owner of the majority of his Shares, Jacob Wallenberg was a famous nazi, he got a nazi achievement iron cross 1941, and his family knew Herman Göring. There account was frozen in the Bosch affair after ww2 because of nazi involvement.
Yes he had some loans but who doesnt these days? Amazon has gone - each year but they growing, so did Ivar, he could have easily fixed the situation, based on the suecide note it looks hasty with no details and heart to it considering his position.
There was never a public hearing of suspision to murder.
This is a huge piece in history
