The story of the word

Two senses share the word. Galton, Pearson and Weldon founded the journal Biometrika in 1901 for the statistical study of variation in populations, and that discipline still calls itself biometry. The security sense, fingerprints and iris scans, grew from the same measuring impulse but points at one person rather than a distribution.
