Bosch is 100% German. Not overly pro Nazi record at all, some say helped to fund resistance to Nazis. Bosch the original founder in the 19th century had Jewish origins but converted to Christianity. Bosch is a privately owned ( christian) family firm with philanthropic history.
The word Bosch is often used in slang as another word for German, compared to other German companies such as Bayer or Volkswagen positively angelic! I try not to buy German products, yes world hates us , but Nazi genocide was colossal and its legacy lives on with deep scars in our subconscious.
