A perennial social fixture in New York and Palm Beach, these days zaftig Gubelmann owns a line of home products, Vie Luxe.

Marjorie is a blue blood to the core: Her grandmother, Barton Gubelmann, was the "first lady" of Palm Beach high society during the middle part of the 20th century, and her yachtsman grandfather, Walter Gubelmann, won America's Cup in the 1960s. A third generation Palm Beacher, Marjorie made a name for herself in New York thanks to her hostessing abilities and regular appearances at events around town. Her day jobs, not surprisingly, have been rather negligible: Back in the '90s, she invested money on behalf of her family and described herself as a "venture capitalist." But she picked up a brand new hobby in 2004 when she teamed up with fellow socialite Daniel Benedict to launch Vie Luxe, a line of scented candles and sprays. Inspired by Gubelmann and Benedict's "favorite travel destinations" and their "passion for luxurious living," Vie Luxe had an auspicious start—but it turned out all was not well with the venture when, in July '08, she announced she was suing Benedict for mismanagement and to stop him from setting up a rival company. The former best friends are now, sad to say, bitter enemies. [Image via Getty]
