The 1949 sole-author derivation; later clinical validations and devices excluded.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is Weir’s exact 1949 paper and its gas-exchange calculation methods. Earlier calorimetry, later validation and reformulation, instrument implementations and every downstream study remain separate.
