## Early life and family

Born on 14 August 1968 at Fischbach Castle, Fischbach, Luxembourg, he is the second child and only son of Prince Charles of Luxembourg, second son of Charlotte, Grand Duchess of Luxembourg, and Prince Felix of Bourbon-Parma, and his American-born wife, Joan Douglas Dillon, second daughter of politician and diplomat C. Douglas Dillon. He has one older sister half-sister from his mother's previous marriage and one older sister, Princess Charlotte (born 15 September 1967). Prince Robert and his sister were raised at Fischbach Castle, which was then the home of his paternal grandparents. Their mother is a Catholic convert, having done so in 1953.
Prince Robert was educated first at a primary school in Belair before attending Worth School, a Roman Catholic boarding school near Worth, West Sussex, United Kingdom. He studied philosophy and psychology at Georgetown University but left university before graduating to travel through the Middle East and North Africa, India, Nepal, and South America.
On 29 January 1994, Prince Robert married Julie Elizabeth Houston Ongaro (born 9 June 1966) in Boston, Massachusetts. They have three children:
* Princess Charlotte Katherine Justine Marie of Nassau (born 20 March 1995), who married Mansour Nicolas Frederic Shakarchi (born 1997 in Geneva) in January 2025, son of Marwan Mahmoud Shakarchi and Tatiana Frick
* Prince Alexandre Théodore Charles Marie of Nassau (born 18 April 1997)
* Prince Frederik Henri Douglas Marie of Nassau (18 March 2002 – 1 March 2025)
As their marriage was non-dynastically approved, his wife was initially known only as "Julie de Nassau" and their children initially bore the titles "Count/Countess of Nassau". On 27 November 2004, Grand Duke Henri issued an Arrêté grand-ducal upgrading his wife and their issue to the titles of "Prince/Princess of Nassau" with the style of Royal Highness.
Prince Robert's youngest son Frederik died in Paris on 1 March 2025 from POLG congenital mitochondrial disease. He had been diagnosed with the disease when he was 14.

## Career

In 1992, Prince Robert and his future wife wrote a screenplay based on Don Juan. This caught the eye of Steven Spielberg and Creative Artists Agency. He left screenwriting to join the family wine business.
