Geology and Minerals
Eugene Woldemar Hilgard (January 5, 1833 – January 8, 1916) was a German-American expert on pedology (the study of soil resources). An authority on climate as a soil forming factor, soil chemistry and reclamation of alkali soils, he is considered as the father of modern soil science in the United States.
