Note: According to Desiré Massart, et al., Handbook of Chemometrics and Qualimetrics, Part A (Elsevier, 1997), p. 13, the word was introduced by the Swedish chemist Svante Wold in a paper published in 1972 ("Spline-funktioner–ett nytt verktyg i data-analysen," Kemisk tidskrift, vol. 3, 34-37): "This name was mentioned for the first time by Wold in a paper published in a Swedish journal on the application of splines to fit data. He christened his group 'Forskningsgruppen for [sic] Kemometri'…." Svante Wold himself has stated that he used the word in 1971 in a grant proposal to a Swedish funding body ("SwNSRC" – a Swedish equivalent of the U.S. National Science Resources Center?) (see "35 Years of Chemometrics," talk given by Wold at a meeting of the International Biometrics Society, British and Irish Region, York, England, March 31, 2006—illustrations from the talk were formerly on line at
