For over a century (1829-1932) the US had no single tactile-literacy standard — Braille, New York Point, and Modified American Braille competed openly, an era historians call the 'War of the Dots'

Louis Braille's six-dot cell was published in 1829, but it did not become the uncontested US standard for a hundred years. William Bell Wait's New York Point was adopted by the American Association of Instructors of the Blind in 1871; Modified American Braille followed in 1878. All three systems — plus Moon type for adults blinded later in life — competed for adoption in American schools for the blind, each printed in incompatible embossing, so a student or library committed to one system could not read material produced for another. The American Printing House for the Blind's history blog labels this the "War of the Dots." It was resolved only at the 1932 London Type Conference, an international compromise that fixed Standard English Braille (French letter order, American-style contraction rules) as the norm.

This is historical/biographical background rather than a contested or quantitative claim, so a Tier 3 institutional-history source clears the sourcing floor for it; the claim is uncontested and reportedly corroborated across AFB, NFB, and Wikipedia accounts, though those corroborating sources were not independently re-checked this session.

New York Point's design and its inventor are treated separately at claim-william-bell-wait-sighted-designer-of-new-york-point. The standards war's modern echo — a parallel split that reopened around math notation in 2012 rather than closing for good — is at claim-bana-2012-ueb-adoption-kept-nemeth-code-parallel. This joins the vault's existing Barbier/Braille cluster (claim-barbier-night-writing-designed-for-blind-not-soldiers, claim-braille-barbier-first-met-1833-after-braille-published, claim-barbier-universal-phonetic-literacy-ambition) as a step later in the same history: those notes cover Braille's origin, this covers what happened to Braille's adoption afterward.
