He is a descendant of the Andlau family, a very old family of Alsatian nobility.
Guillaume d'Andlau began his professional career at the United Nations Development Programme (UNDP) in Laos. He volunteered to go to Rwanda during the 1994 genocide and was sent as a volunteer for the French Red Cross to Goma in Zaire, now the Democratic Republic of Congo. He remained with the French Red Cross as a program manager and later as the executive director of international operations until the end of the 1990s. In 1999, he was appointed director of the Economic and Social Council of Alsace.
He later worked as the head of sponsorship at Crédit Agricole SA and then as a "communications officer" for the same bank in 2012.
From 2019 to the end of 2023, Guillaume d'Andlau served as the director of the European Centre for the Deported Resistance Fighter. He succeeded historian Frédérique Neau-Dufour in this role.
Politics
In 2016, Guillaume d'Andlau ran, unsuccessfully, in the by-election as an independent candidate in the first constituency of Bas-Rhin. He garnered nearly 6% of the vote. In the 2017 legislative election, he sought the nomination of La République En Marche but failed to secure it and did not stand as a candidate.
Associative Engagement
In 2000, Guillaume d'Andlau founded the Association des amis du château d'Andlau, dedicated to the preservation and maintenance of the family-owned, ruinous château, which has been in his family since the 13th century. He became the owner of the château in 2004. He has invited various cultural figures, including the artist Frank Morzuch, to the château to help promote its heritage.
