Prominent ancestor: Belgian caricaturist Pierre Kroll acquires Luxembourgish nationality

One of Belgium’s best-known caricaturists and cartoonists has acquired Luxembourgish nationality by option, citing family ties to his great-uncle, William J. Kroll, the Luxembourg-born metallurgist who developed the Kroll process in the late 1930s, a breakthrough that enabled the industrial production of titanium in the early 1940s.
