His Royal Highness Prince Louis Xavier Marie Guillaume, Prince of Luxembourg, Prince of Nassau and Bourbon-Parma, is the third son of Their Royal Highnesses Grand Duke Henri and Grand Duchess Maria Teresa of Luxembourg. 

He has two sons from his first marriage with Tessy Antony: Prince Gabriel Michael Louis Ronny, born in Geneva on 12 March 2006 and Prince Noah Etienne Guillaume Gabriel Matthias Xavier, born in Luxembourg on 21 September 2007.

After attending primary school in Lorentzweiler, Prince Louis began his secondary education at the American School of Luxembourg. He then went to the Collège Alpin Beau Soleil in Switzerland, where he continued his studies and obtained a secondary school diploma in June 2005.

Prince Louis is fluent in Luxembourgish, French, English and German and has a very good knowledge of Spanish.

While he studied in Switzerland, Prince Louis became particularly interested in social and humanitarian work. He took part in missions in Mumbai, India, led by an NGO in cooperation with his school. During his school holidays, he taught English, mathematics and physical education to children living in the most disadvantaged neighbourhoods.

Prince Louis pursued his interest in the humanitarian sector and in 2006, he spent a year working for the Red Cross in Geneva in various fields, such as logistics and event organisation. He also participated in the supervision of children’s groups and the support of elderly people.

In 2007, Prince Louis worked in forestry management for the Administration of the Assets of H.R.H. the Grand Duke. In 2008, he decided to take courses at the Miami University Dolibois European Center in Luxembourg.

He then spent two years in the United States, where he completed a training course in Aeronautics, granting him a private pilot licence in 2011. After this, he moved to the United Kingdom, eager to continue his studies.

In 2014, Prince Louis obtained a degree in Communication at Richmond, the American International University in London. In 2015, he trained at the European Landowners Organization, which is committed to the promotion of sustainable and prosperous rural regions and to raising awareness of environmental and agricultural issues in Europe.

Subsequently, Prince Louis completed his studies at Birkbeck University in London and now holds a Master’s degree in Psychosocial Studies. Through his own personal experience, Prince Louis has gained a deep understanding of and willingness to support people with dyslexia. He also trained with Béatrice Sauvageot, a recognised expert in this field. Prince Louis spoke about his dyslexia during the International Forum on Learning Disabilities, organised by the Fondation du Grand-Duc et de la Grande-Duchesse (Foundation of the Grand Duke and the Grand Duchess) in 2016.

He is also a graduate mediator of the Université catholique de Paris and holds the international certificate issued by the Center for Effective Dispute Resolution (CEDR). Prince Louis worked as a consultant for Laurent Meeschaert Conseil in Paris from 2017 to 2019, before setting up his own business. Since 2020 and the launch of his own company, SIBE Mediation, he has helped people with dyslexia to gain a greater understanding of the condition; he also provides advice on how to manage dyslexia in the workplace.

His company, established in Paris with three partners, is the result of combining his expertise as a mediator with that of psychosocial and legal professionals.

Whenever his schedule allows it, Prince Louis returns to Luxembourg and takes part in the activities of the Grand Ducal Family, such as the National Day or the last day of the traditional Octave. He also takes part in major family events, such as religious services for the Grand Ducal Family or, more recently in 2019, the centenary of the accession to the throne of H.R.H. Grand Duchess Charlotte.

Because sports can teach values such as fairness, equality, perseverance and respect, Prince Louis has accepted to be the patron of the Luxembourg Table Tennis Federation (since 2004), the Martial Arts Federation (since 2010) and the Luxembourg Aeronautical Federation (since 2011). In this context, he regularly attends sporting events, such as the European Table Tennis Championship (in 2017), the Kagami Biraki (judo, in 2019), the Prince Louis Cup (karate, in 2014 and 2016) or the fencing tournament of the European cadet circuit in 2019.

Prince Louis has held the Order of the Gold Lion of the House of Nassau since 2004.

A fervent amateur of various sports disciplines which he practises assiduously, Prince Louis has a particular passion for mountain sports (downhill skiing, snowboarding, climbing…) as well as table tennis, martial arts, fencing, horse riding, scuba diving and hunting. The Prince is also an avid pilot.

His children thus learn about self-respect and respect for others, the benefits of spending time in nature, the importance of enjoying and being mindful of everything around us in order to deepen their environmental values. Prince Louis enjoys special moments with his children, such as teaching them skiing and other sports or playing strategy games.
