Donald John Trump (born June 14, 1946) is an American business magnate, socialite, author and television personality. He is the Chairman and CEO of the Trump Organization, a US-based real-estate developer. Trump is also the founder of Trump Entertainment Resorts, which operates numerous casinos and hotels across the world. Trump's extravagant lifestyle and outspoken manner have made him a celebrity for years, a status amplified by the success of his NBC reality show, The Apprentice (where he serves as host and executive producer).

Donald was the fourth of five children of Fred Trump, a wealthy real estate developer based in New York City. Donald was strongly influenced by his father in his eventual goals to make a career in real estate development, and upon his graduation from the Wharton School of the University of Pennsylvania in 1968, Donald Trump joined his father's company, The Trump Organization.

Starting with the renovation of the Commodore Hotel into the Grand Hyatt with the Pritzker family, he continued with Trump Tower in New York City and several other residential projects. Trump would later expand into the airline industry (buying the Eastern Shuttle routes), and Atlantic City casino business, including buying the Taj Mahal Casino from the Crosby family, then taking it into bankruptcy. This expansion, both personal and business, led to mounting debt. Much of the news about him in the early 1990s involved his much publicized financial problems, creditor-led bailout, extramarital affair with Marla Maples, and the resulting divorce from his first wife, Ivana Trump.
