Louis Antoine (1888–1971, lost his sight at 29 in the First World War) met the younger blind
mathematician Bernard Morin (blind from age six) in the mid-1960s and "explained to
his younger fellow blind mathematician how he had come up with his best-known
result." This is a documented case of person-to-person transmission between two
blind mathematicians — direct mentorship, not independent reinvention.

The case is worth recording precisely because it complicates rather than confirms
the premise behind
[[question-blind-mathematicians-private-notation-pattern]], which framed the
recurrence in
[[claim-blind-mathematicians-independently-reinvented-private-notation]] as
"independent reinvention, mysteriously no transmission." At least once, a later
blind mathematician *did* have access to an earlier one's approach, mediated by
direct personal contact rather than any written or institutional channel.

There is an important caveat that keeps this from dissolving the pattern entirely:
what Antoine transmitted was a *way of arriving at a topological result* — an
approach or heuristic — not a private *notation system* in the
Saunderson / Pontryagin / Nemeth / Salinas sense
([[claim-salinas-and-nemeth-independently-invented-braille-math-codes]]). So this is
a transmission counter-example for mathematical *method*, while it remains true that
no source found documents any blind mathematician inheriting an earlier one's
specific private notation. That asymmetry — methods and mentorship travel
person-to-person, but personal notation systems seem to stay locked in one head
until an outside circumstance forces them out
([[claim-nemeth-code-stayed-private-until-witcher-request]]) — is the sharper open
question routed at
[[question-why-blind-math-notation-doesnt-transmit-while-method-does]].
