Théophile de Giraud is a writer, philosopher, and Belgian activist of French language born in Namur on November 19, 1968.
A figure of the antinatalism and childfree movement, he is one of the co-creators of Non-Parents Day, celebrated between 2009 and 2011, alternately in Brussels and Paris.
In 2008, he covered a statue of Leopold II in Brussels with red paint, to denounce the public valorisation of the king who established the colonial system of the Belgian Congo.
In 2012, he organised a "denatalist" event in Paris to bring attention to the overpopulation taboo and to the value of refusing to give birth for ecological reasons.
