Karl Albrecht

The German billionaire entrepreneur who founded discount supermarket chain Aldi and one of the richest people in the world according to Forbes. As of 2010, Aldi had more than 4,000 stores in Germany plus another 8,000-plus stores in Australia, France, Great Britain, Greece, Poland, Portugal, Spain, Switzerland and the United States amongst other countries. It's biggest competitor is another German discount supermarket chain, Lidl.

In addition to groceries, Aldi also sells skin care products and some household items. Aldi primarily sells its own brand of products.
