Dieter Schwarz controls the Schwarz Group, the largest closely held
discount grocer in Europe, which operates the Lidl and Kaufland
supermarket chains. He controls the companies through the Dieter Schwarz Stiftung, a limited liability company with a charitable purpose. The group has more than 10,000 stores in Europe and generated $83 billion in 2011 sales.
On a recent Saturday afternoon at a Lidl supermarket in London, a 500-gram slab of minced beef was on sale for 2 pounds ($3.21), half the price of the same product at a Sainsbury Local store a few blocks away.
