Being married to the founder of the eponymous German department store chain, Heidi Horten inherited an estimated $1 billion fortune from him, when he died in 1987. Heidi met the 32-years her senior husband in a hotel bar in Velden am Wörthersee in 1960.

Having succeeded her husband's fortune, Helmut became one of the top ten women billionaires. Actually, she has been listed as the world's 3rd richest billionaire. Now she divides her time between a penthouse in Vienna, a residence in Tessin, Switzerland, and a home in Lyford Cay in the Bahamas.

She doesn't have immediate heirs, because Heidi and Helmut didn't have any children.
