Who owns Trader Joe?

Can you tell me who the owner of Trader Joe's is? I've heard some rumors about the company's ownership structure, but I'm not sure if they're true. I'm interested in understanding more about the background and history of the company, and I'm wondering if you can provide any insights into its ownership. Additionally, I'm curious about the motivations and goals of the owner, and how they may influence the direction of the company in the future. Can you help me shed some light on these questions?
