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.
