Gerard Adriaan Heineken, born in 1841, was a driven young entrepreneur from an Amsterdam merchant family. At just 22, he bought the aging De Hooiberg brewery and transformed it through innovation, science, and strict quality standards. Though not a brewer himself, his vision led to rapid success, international recognition, and the founding of Heineken’s Bierbrouwerij Maatschappij, laying the groundwork for a globally recognized, family-owned brand.
