What I really like about the Bosch company/foundation relationship is the way the funding for the foundation is structured. The foundation does not engage in corporate activity, but holds 92% of the shares in order to fund its activities. The voting rights for those shares are transferred to the Robert Bosch Industrietreuhund KG trust that then decides how to vote. This separates the business from the foundation, enabling both to make the decisions they think are best for their purposes. I think that's awesome.

The funding structure
The Bosch House - Some of the furniture is original, but not all of it. The house changes hands a few times, particularly during the war periods, and it took a while for the company to buy the house back and locate some of the furniture.
