German polymath (1646–1716) who developed calculus independently of Isaac
Newton and originated much of its still-used notation, including the
integral sign.

Matters to this vault in two distinct threads it doesn't share a page
before now: as the figure whose "prestige" both
[[claim-notation-adoption-decided-by-institutional-power-not-usability-alone]]
(citing Zhang et al.'s paraphrase) and
[[claim-cajori-1928-hedges-leibniz-prestige-and-credits-newton-too]] (citing
Cajori directly) name in explaining why Robert Recorde's "=" beat Descartes'
rival symbol — though the two sources weight his role differently, one
crediting him alone, the other crediting him and Newton jointly — and,
separately, as one half of the Newton–Leibniz pair
[[claim-independent-notation-reinvention-is-general-pattern-not-blindness-specific]]
cites as the paradigm case of two people independently inventing notation
for the same problem.
