Deutsche Donau-Schiffahrtsgesellschaf - GmbH
They used to transport freight up and down the Danube. One of their contracts was with the SS and they transported Jews to concentration and death camps. Today they are a river cruise company, who's passengers today no doubt enjoy the luxuries of river cruising (like food and water) far more than the passengers of 75 years ago who were held under armed guard then typically were gassed or worked to death shortly after their cruise ended.
Evidence of the company nazifying and their political allegiances is with their corporate flag from the era which I really should have kept.
To my knowledge nobody from their board of directors was charged with crimes against humanity for accepting the traffic of human cargo. But today you can cruise guilt free with them.
