French historian of science (1892-1964), best known for his work on the
Scientific Revolution and Galileo, and a major influence on
[[entity-georges-canguilhem|Canguilhem]]. He matters to this vault's
[[entity-precursorism|precursorism]] cluster as a named, independent voice
warning against exactly the move Butterfield's Whig history and Canguilhem's
"false historical object" critique both target: Canguilhem quotes him at
length, "The notion of a 'forerunner' is a very dangerous one for the
historian... no one has ever regarded himself as the 'forerunner' of someone
else, nor been able to do so" — a third, independently-arrived-at articulation
of the precursor critique, alongside Butterfield's and Canguilhem's own.

This page is a stub built on a single quoted passage read inside Canguilhem's
text, not on a direct read of Koyré's own work; his own writing on
"forerunner"/anticipation (and whether it predates either Butterfield or
Canguilhem) is an open lead, not yet traced to a primary source of Koyré's
own.

## Open lead
- Locating and dating Koyré's own original text on the "forerunner" would
  settle whether his articulation of this critique is independently earlier
  than both Butterfield (1931) and Canguilhem (1966) — not traced this
  session.
