Prince Guillaume of Luxembourg

Prince Guillaume Marie Louis Christian of Luxembourg was born May 1, 1963 at Betzdorf Castle in Luxembourg. He is the youngest child of Grand Duke Jean of Luxembourg and Princess Joséphine-Charlotte of Belgium.

Following his primary and secondary schooling in Luxembourg, Switzerland and France, Prince Guillaume attended the University of Oxford, in England, and Georgetown University in the US, graduating from Georgetown in 1987. He worked for six months in the office of the Executive Director of the International Monetary Fund in Washington DC, and then two years for the Commission of the European Communities in Brussels, Belgium. In 1982, he became President of Lux-Development, the company that runs the bilateral and intergovernmental program of development assistance to the government of Luxembourg. In addition, he serves as a director of Arcelor-Mittal and Banque Générale du Luxembourg. He serves as patron of the Luxembourg Basketball Federation and the youth section of the Prince Guillaume Municipal Band of the city of Differdange.

Prince Guillaume is married to Sibilla Weiller, a distant cousin. She is a granddaughter of Infanta Beatriz of Spain, and a second cousin to King Felipe VI. They were married first in a civil ceremony held on September 8, 1994 in Sélestat, France, followed by a religious ceremony on September 24, 1994 at the Versailles Cathedral (Cathédrale Saint-Louis de Versailles). The couple have four children:

  • Prince Paul Louis of Nassau (1998)
  • Prince Léopold of Nassau (2000)
  • Princess Charlotte of Nassau (2000)
  • Prince Jean of Nassau (2004)

In September 2000, Prince Guillaume and Princess Sibilla were injured in a serious car accident in France, the prince spending some time in a coma. Due to the accident and the prince’s condition, his father’s planned abdication as Grand Duke of Luxembourg, scheduled for September 28th, was postponed until the first week of October. Prince Guillaume and his family live in Luxembourg, and are often in attendance at major events in the Grand Duchy, as well as most family functions.
