Robert Recorde
16th-century Welsh physician and mathematician credited with introducing the "=" symbol in 1557, per Florian Cajori's A History of Mathematical Notations — the originating act behind a symbol that went on to win out over a rival introduced by Descartes.
Matters to this vault as the originating historical actor in the equality-sign story that claim-notation-adoption-decided-by-institutional-power-not-usability-alone and claim-cajori-1928-hedges-leibniz-prestige-and-credits-newton-too both turn on: both notes are about why his symbol beat Descartes', not about Recorde himself, so this page is deliberately thin — a placeholder for the one fact currently on record (the 1557 introduction) rather than a biography. Cajori's own §260–263, covering Recorde's original introduction in detail, was flagged as unread in the capture that created this page; a fuller account belongs here once someone reads it.
