Deceased King of Thailand, Bhumibol Adulyadej was the richest royal in the world with an estimated net worth of $30 billion as of May 2014, according to Forbes. He died on 13 October 2016 leaving behind one of the richest estates in the world. This estimated include property and investments managed by the Crown Property Bureau. King Bhumibol Adulyadej reigned for 64 years, making him the longest reigning monarch in history and the longest serving head of state in the world. He is credited with the social-economic theory of self-sufficiency, something he developed throughout his long years of study. He owned a fairly large stake in the publicly listed Siam Cement and Siam Commercial Bank, as well as Deves Insurance which was forced to go private due to the amount he invested. Although King Bhumibol had relatively little power as a constitutional monarch, he intervened in Thai politics many times to help resolve crises and stories of his poor health have led to sell-offs on the Thai Stock Exchange. The king also made generous contributions to different sectors of Thai society.
The King was born in Cambridge, Massachusetts, United States on 5 December 1927 at the Mount Auburn Hospital and died in Bangkok, Thailand. He attended Ecole Nouvelle de la Suisse Romande in Lausanne, and University of Lausanne in Switzerland.
