History
=Nadar=
Brussels mayor Jules Anspach has been credited with the invention of the crowd control barrier for the occasion of the visit of the French photographer Nadar to Brussels. On his visit to Brussels with the balloon Géant, on September 26, 1864, Anspach erected mobile barriers to keep the crowd at a safe distance.https://bruges-la-morte.net/wp-content/uploads/Baudelaire_Bruxelles.pdf {{Bare URL PDF|date=March 2022}} Up to this day, crowd control barriers are known in both Belgian Dutch and Belgian French as Nadar barriers.[http://www.cornille-mct.be/fr/nadar.html Nadarafsluiting] at www.cornille-mct.be
