Howard Robard Hughes Jr. (December 24, 1905 - April 5, 1976) was an American business magnate, investor, record-setting pilot, film director, and philanthropist, known during his lifetime as one of the most financially successful individuals in the world. He first made a name for himself as a film producer, and then became an influential figure in the aviation industry. Later in life, he became known for his eccentric behavior and reclusive lifestyle--oddities that were caused in part by a worsening obsessive-compulsive disorder (OCD), chronic pain from several plane crashes, and increasing deafness. As a maverick film tycoon, Hughes gained prominence in Hollywood beginning in the late 1920s, when he produced big-budget and often controversial films like The Racket (1928), Hell's Angels (1930), and Scarface (1932).

Beyond extending his business prowess in the manufacturing, aviation, entertainment, and hospitality industries, Hughes was a successful real estate investor. Hughes was deeply involved in the American real estate industry where he amassed vast holdings of undeveloped land both in Las Vegas and in the desert surrounding the city that had gone unused during his lifetime. In 1968, the Hughes Tool Company purchased the North Las Vegas Air Terminal.  Originally known as Summa Corporation, The Howard Hughes Corporation was formed in 1972 when the oil tools business of Hughes Tool Company, then owned by Howard Hughes Jr., was floated on the New York Stock Exchange under the Hughes Tool name. This forced the remaining businesses of the "original" Hughes Tool to adopt a new corporate name Summa. The name "Summa"--Latin for "highest"--was adopted without the approval of Hughes himself, who preferred to keep his own name on the business, and suggested HRH Properties (for Hughes Resorts and Hotels, and also his own initials). In 1988, Summa announced plans for Summerlin, a master-planned community named for the paternal grandmother of Howard Hughes, Jean Amelia Summerlin.  Initially staying in the Desert Inn, Hughes refused to vacate his room, and instead decided to purchase the entire hotel. Hughes extended his financial empire to include Las Vegas real estate, hotels, and media outlets, spending an estimated $300 million, and using his considerable powers to take-over many of the well known hotels, especially the organized crime connected venues. He quickly became one of the most powerful men in Las Vegas. He was instrumental in changing the image of Las Vegas from its Wild West roots into a more refined cosmopolitan city.
