The Wackenhut Corporation is a Unite States-based private security and investigation firm, and is headquartered in Palm Beach Gardens, Florida. Wackenhut was founded in 1954, in Coral Gables, Florida, by George Wackenhut and three partners, all former FBI agents. After early struggles — including a fistfight between Wackenhut and one of his partners — he took sole control of the company in 1958, naming it for himself. After working all day in the office, he sometimes worked as a security guard at night. By 1964, he had contracts to guard the Kennedy Space Center in Florida, as well as the U.S. Atomic Energy Commission's nuclear test site in Nevada; the company had an initial public offering the next year. In 2002, the company was purchased by Danish corporation Group 4 Falck (now Group 4 Securicor) for $570 million. At the time, the company operated in 54 countries, had $2.8 billion in revenue, and its founder still controlled more than 50% of its stock.
