As reported by the Belgian newspaper La Dernière Heure on Saturday morning, Pierre Kroll, who lives in Liège and was born in what was then the Belgian Congo, said in the interview that he obtained Luxembourgish nationality by option after proving that he has Luxembourgish ancestors.
His great-uncle was none other than Guillaume Justine Kroll (also known as William J. Kroll), who was born in Esch-sur-Alzette in 1889 and holds an international reputation for having developed a process to produce titanium in the 1930s. The largest secondary school in Esch-sur-Alzette as well as the street Rue Guillaume J. Kroll in Cessange are both named after him, something the Belgian cartoonist also pointed out in the interview.
