Lorentz Formula Reference Weight
The Lorentz reference weight (1929) — Broca refined with a sex-specific correction, still quoted in European texts.
Lorentz softened Broca's straight 'height − 100' with a height-dependent subtraction, giving more plausible values for tall adults. French and German clinical literature still cites it; like every reference-weight line it describes a statistical convention from the 1920s, not an individual prescription.
