(1843–1917; b. Freiburg, Germany; d. Potsdam, Germany)
German mathematical physicist. Helmert's interest in statistics resulted from his research in geodesy (the study of distances and angles between widely separated locations on the Earth's surface). He was Professor of Geodesy at U Aachen in 1872, and at U Berlin in 1887, where he became director of the Prussian Geodetic Institute. His research included fundamental work on the chi-squared distribution.
