Donald Trump's first wife and mother of Ivanka, Donald Jr. and Eric Trump, Ivana Trump was a model, a socialite, a competitive skier, an interior designer, a fashion-and-perfume mogul, and a behind-the-scenes force on many of Trump's most important deals of the 1980s. With her passing last year, Ivana's estate has put her home, an opulent Manhattan townhouse, on the market for $26.5 million.
