Philippa Campsie

Historian; primary researcher behind the vault's entire Barbier/Braille myth-correction cluster. Worked from Barbier's own papers and correspondence (Association Valentin Haüy, Institut National des Jeunes Aveugles, Musée Louis Braille) to overturn the standard "secret military code for soldiers" origin story for Charles Barbier's raised-point "night writing," and to retrace how that story and a separate fabricated Braille–Barbier rivalry scene entered the record. Published as "Charles Barbier: A hidden story" (Disability Studies Quarterly 41(2), 2021) and popularized on her own blog (parisianfields.com, 2021); the vault independently corroborated the core chronology in 2026 via a recorded 2024 UKAAF interview transcript, a second source distinct from the original blog post.
