Jeroen De Bruyn was born in 1993 in Antwerp. At age fifteen—the same age as Anne when she died of typhus in the Bergen-Belsen concentration camp—Jeroen began doing original research on the Secret Annex. He got to know the Anne Frank House firsthand during an internship there in 2011. He went on to study journalism, subsequently contributing to prominent Flemish news magazines like Knack and Joods Actueel, and working as a senior editor for the major Belgian newspaper Gazet van Antwerpen.
