From the
Freakonomics Blog:Who owns Trader Joe’s?
1. Some great California family full of surfers and gardeners.
2. A small band of communal farmers in Oregon.
3. A huge German discount-grocery chain best known in the U.S. for no-glamor stores often located in marginal neighborhoods.
You probably guessed correctly: Trader Joe's is German, though the blog isn't quite correct. From
Wiki: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.
