Hi,
He was a senior person (just below board level) Lufthansa, he took early retirement when the Berlin wall came down. Speaking to the Photographer, he uses his pension and the rental income off his family home. He lives very frugally with a set and separate budgets for food, fuel, and parts. Most of his expense is moving from country to country by ship.
I don't think he could be classed as wealthy but he certainly was not poor to start with.
I don't know if he ever had kids but I'll ask.
