Her Royal Highness Princess Claire of Luxembourg, born Claire Margareta Lademacher, is the second child of Hartmut and Gabriele Lademacher. Claire has an older brother, Félix Lademacher. She spent her childhood with her family in Usingen (district of the Hoher Taunus, Germany).

In December 2012, the Office of the Marshal of the Court announces the engagement of Prince Félix and Claire Lademacher. Their wedding takes place on 21 September 2013 in the Basilica of Sainte Marie-Madeleine de Saint-Maximin-la-Sainte-Baume in France. Upon her wedding, she received the title of 'Her Royal Highness Princess Claire of Luxembourg, Princess of Nassau'.

Princess Claire and Prince Félix are parents to a daughter and two sons: Princess Amalia Gabriela Maria Teresa, born on June 15, 2014, at the Maternité Grande-Duchesse Charlotte in Luxembourg; Prince Liam Henri Hartmut, born on November 28, 2016, at the Clinique Générale-Beaulieu in Geneva; and Prince Balthazar Félix Karl, born on January 7, 2024, at the Maternité Grande-Duchesse Charlotte in Luxembourg.

After completing her primary school education in Germany, Princess Claire and her family moved to Atlanta (USA), where she attended the Atlanta International School. In addition to German, her native language, Princess Claire speaks English, French and Italian.

In 1999, the Lademacher family returned to Germany. Princess Claire then attended the Frankfurt International School before spending two years at the boarding school of the Collège Alpin Beau Soleil in Switzerland, where she met Prince Félix. In 2003, she obtained the English A-Levels diploma with honours (Prize of Excellency).

Princess Claire studied International Communications at the American University of Paris, where she graduated in 2007.

She gained some first-hand work experience at the Condé Nast publishing house in New York and Munich, before working at IMG World in Berlin.

In 2009, after obtaining a Master's degree in Bioethics with summa cum laude at the Ateneo Pontificio Regina Apostolorum University in Rome, Princess Claire wanted to deepen her knowledge and enrolled in doctoral studies in the same field. Simultaneously, she worked for the UNESCO Chair of Bioethics and Human Rights. In order to obtain her PhD, Princess Claire presented her thesis on the ethical aspects of consent to organ donation in Rome. As part of the research for her thesis, she was invited as guest researcher at the Kennedy Institute of Ethics at Georgetown University in Washington D.C.

Together with her husband, Prince Félix, Princess Claire has been managing the Château les Crostes wine estate in Lorgues since 2013 and she is co-founder of the Young Empire company, a children’s clothing and decorating brand.

Alongside her professional and family commitments, she is still closely following the developments in the field of bioethics. In February 2018, Princess Claire was a visiting professor at the Faculty of Bioethics at the Ateneo Pontificio Regina Apostolorum University in Rome. In March 2018, the Princess attended the Ethics in Action ('Modern Slavery, Human Trafficking, and Access to Justice for the Poor and Vulnerable') conference at the Pontificia Academia Scientiarum of the Vatican.

In March 2019, she was a speaker in the panel discussion on the inclusion of children born of rape at the Stand Speak Rise Up! conference organised at the initiative of H.R.H. the Grand Duchess.

Inspired by her parents, Princess Claire has always shown an interest in social and cultural issues. She has managed to combine her extensive travels with an involvement in humanitarian projects, for example in Tiruppur, India.

Princess Claire is a voracious reader who loves autobiographies. She also practices yoga, pilates and plays badminton. She has been passionate about photography since her teenage years, with a particular emphasis on nature.

Since August 2018, Princess Claire lives in Frankfurt/Main (Germany) with her husband and their two children. She enjoys baking and drawing with her children. Being very committed to her children's education, she helps them discover the joy of learning and understanding the world.
