Albert Frere, who was the richest person in Belgium, turned his family's scrap-metal business into a media, utilities and oil empire Albert Frere' s business interests included Groupe Bruxelles Lambert (GBL bank), insurer Royale Belge, Petrofina and Tractebel before he began slowly selling off assets later in his career.
