• Germany's richest man.
• After World War II,  Karl and his younger brother, Theo, developed their mother's corner grocery store into discount supermarket giant Aldi, which now has more than 8,000 stores and $67 billion in sales. They eventually split ownership and management of the chain into North and South regions.
• Now retired, Karl used to manage more profitable southern half of Aldi's business in Germany.
• Fiercely private: little known about him other than that he apparently raises orchids and plays golf.
