Albrecht learned the
grocery business from his mother, in order to escape the fate of his father, who was the miner. In 1946, he and his brother Karl developed
Albrecht Diskont, with the motto "the best quality at the lowest price", now one of Europe's largest chains of supermarkets, known by the acronym Aldi. In 2014,
Forbes estimated Albrecht's fortune at approximately £11 billion (). Theo and Karl Albrecht split the Aldi company in 1960 after a dispute about whether or not to sell cigarettes. The supermarket divided into two legally separate operating units, with two distinct geographical locations. Theo's Aldi Nord operated in the north of Germany, while Karl's Aldi Süd was based in the south. Albrecht retired from daily operations in 1993 and remained as chairman of the company's board. == Kidnapping ==
