Early life and background

Gustaf Archibald Siegwart Douglas was the oldest son of Carl Ludvig Douglas (1908–1961), a Swedish nobleman and diplomat who was the Swedish Ambassador to Brazil, and his Prussian wife Ottora Maria Haas-Heye (1910–2001). He had two younger sisters. The older is Elisabeth Douglas (b. 1940), who married Prince Max, Duke in Bavaria (brother and heir to the Bavarian and Jacobite pretender Franz, Duke of Bavaria) and had five daughter including Sophie, Hereditary Princess of Liechtenstein. The younger sister is Rosita Douglas (b. 1943), who was the 11th Duke of Marlborough's third wife and mother his three youngest children, though the eldest died as an infant.

His patriline is Scottish, of the Swedish-German branch, descended via two obscure generations,^[3] from the youngest son of James Douglas, 1st Lord Dalkeith, ancestor of the 15th century Earls of Morton. All these Douglases were of the Morton branch of the ancient Douglas family. The Douglas family was introduced in the 17th century at Riddarhuset under number 19 among families of comital status. Gustaf Douglas later served on the board of Riddarhuset.

His maternal great-grandfather was Philipp, Prince of Eulenburg (1847–1921), a friend of Wilhelm II, whose youngest child Viktoria Ada Astrid Agnes Gräfin zu Eulenburg (1886–1967) married in 1909 (divorced 1921) Professor Otto Ludwig Haas-Heye (1879–1959), and had issue, including two daughters. Gustaf descended through both his mother and father from medieval Scandinavian nobility and rulers.

Career

After an MBA from Harvard Business School in 1964, he worked in Sweden and was CEO of the newspapers Dagens Nyheter and Expressen between 1973 and 1980. After that he founded his company Investment AB Latour in 1984, through which he controlled security firm Securitas AB, the lock producer Assa Abloy and more. He formed a partnership with fellow businessman Melker Schörling, who also controls a significant amount of Securitas shares and serves as the company's chairman. He is the eleventh wealthiest person in Sweden, according to Forbes magazine, with an estimated net worth of around US$3.2 billion as of March 2013.

In 2001 Douglas was elected to the board of the Moderate Party. He has a long history of political involvement, having campaigned in his teens for what was the predecessor of the Moderates. Douglas was, however, for a time active within the Liberal People's Party. He was later known as a rather Conservative Moderate with a big interest in education policy.
