TUI AG
The company was founded in 1923 in Berlin, Germany as "Preußische Bergwerks und Hütten-Aktiengesellschaft" operating in the industrial sector. In 1959 it listed on the Frankfurt Stock Exchange and in 1964 was renamed "Preussag". In 2000 it acquired Thomson Travel and in 2002 bought Hapag Lloyd, which itself owned the travel firm TUI (formerly "Touristik Union International"), and renamed itself TUI AG. In June 2014 TUI AG and TUI Travel announced the two companies would be merged.
