CORRECTED: the body compressed Barbier's military record to 'his military service amounted to roughly two days in 1792'; Campsie's account says he trained at the Douai artillery academy from May 1784, rose through the ranks, and it was his *captaincy* that lasted two days (appointed May 18, 1792, quit May 20).

The widely-taught origin story of the tactile writing system that preceded
Braille holds that Charles Barbier de la Serre (1767–1841) invented his
raised-dot *écriture nocturne* ("night writing") as a secret code for soldiers
to read battlefield messages in the dark, and only later carried it to the
Royal Institution for Blind Youth in Paris. Historian [[entity-philippa-campsie|Philippa Campsie]], after
archival work on Barbier's own papers (Association Valentin Haüy, Institut
National des Jeunes Aveugles, Musée Louis Braille) and his 1815 book *Essai sur
divers procédés d'expéditive française*, rejects this flatly: "Balderdash. All
of it. Barbier invented raised point type specifically for blind people."

The corroborating details Campsie reports: Barbier's own 1815 book frames the
system as writing *for blind people*; and though Barbier trained at the
artillery academy at Douai from 1784, his captaincy lasted roughly two days —
appointed captain May 18, 1792, he quit the army on May 20 — not a battlefield
career that would seed a soldiers' cipher. The
soldier-code narrative appears to be a later accretion, not a contemporary
account.

Structurally this is the same failure mode the vault tracks in its ML-history
"priority and myth" cluster: a story hardens into "known fact" across decades of
retelling without a contemporary source underneath it. Compare the
citation-chain version in [[claim-wikipedia-amari-sgd-citogenesis]] and
[[myth-linnainmaa-uncited-before-2010s]], and the presentation-form echo in
[[claim-lamport-paxos-greek-allegory-delayed-publication]]. It also sits beside
the vault's disability-and-technology thread anchored by
[[claim-saunderson-palpable-arithmetic-tactile-calculating-device]] and
[[claim-blind-mathematicians-independently-reinvented-private-notation]]. The
two neighboring facts from the same source live at
[[claim-braille-barbier-first-met-1833-after-braille-published]] and
[[claim-barbier-universal-phonetic-literacy-ambition]].
