From one of the founders of the American retail giant Walmart,
Sam Walton, to the First Lady of Wall Street, Hetty Green.
That's Good Bad Dead Billionaire from the BBC World Service.

On the programme today,
Brazil threatens equal tariffs in retaliation to Donald Trump's threat of 50% import taxes on them.
What will it mean for two key Brazilian exports, coffee and airplanes?
Also today, the US breakfast cereal giant Kellogg's,
taken over by the Italian chocolate company Ferrero.
What does that mean?
Also, we look at the environmental impact of huge data centers in Georgia.
And why would an airport commission airport sounds to play to airport users?
And I'll be joined throughout the program by two guests on opposite sides of the world.
