Theodor Paul Albrecht (born 28 March 1922), generally known as Theo Albrecht, is a German entrepreneur, who in 2009 was ranked by Forbes magazine as the 9th richest person in the world, with a net worth of $18.8 billion. He owns and was the CEO of the Aldi Nord discount supermarket chain. In the US he owns the Trader Joe's specialty grocery store chain. His brother Karl Albrecht owns the Aldi Süd discount supermarket chain. The two chains originally were a single family enterprise until a friendly division of assets in 1960. Aldi Süd operates the Aldi groceries in the United States. So Aldi and Trader Joe's, while owned by the brothers, have separate and distinct ownership and operations.
In 1971, Theo was kidnapped for 17 days. A $3 million ransom was paid for his release. 
Both Albrecht brothers are reclusive and little is known about their private life. The last published photo of Theo Albrecht dates to 1971, one day after his kidnapping. Another photo of the two Albrecht brothers together has been taken in 1987 by the journalist Franz Ruch.
