Kenneth Dart is an heir to the Dart Container fortune who later built a separate investing and real-estate portfolio from his base in the Cayman Islands. [1][3]
The family business
Dart Container grew from a family manufacturing business started in Michigan in 1937. The company perfected a mass-produced expandable-polystyrene cup around 1960 and became Dart Container Corporation in 1963. Its own history says Ken Dart and his brother Bob joined the business as it expanded internationally. [2]
Dart Container remains family-owned. The company says Ken and Bob Dart are owners and members of its board of directors, while day-to-day management is led by a professional chief executive. That continuing ownership links Kenneth Dart's fortune to the packaging company even though his investments extend well beyond it. [3][1]
Investments beyond packaging
Forbes describes Dart as an investor based in the Cayman Islands and says major parts of his portfolio include stakes in British American Tobacco and Imperial Brands, distressed sovereign debt investments and real estate connected with the Camana Bay development. [1]
