Collectors of the UNC Herbarium
Information compiled by Carol Ann McCormick, March 2016


Eugene Woldemar Hilgard
(5 January 1833 – 8 January 1916)

The University of North Carolina Herbarium has catalogued approximately 30 specimens collected by E.W. Hilgard. More may be found as cataloguing of the collection continues. Most of Hilgard's specimens in NCU's collection date from 1858-1867 and are from the southern Mississippi.  Hilgard was catholic in his collecting tastes:  Carex, Pinus, Xyris, Vitis and Sarracenia are represented in NCU’s collection.  He was a prolific writer in both German and English covering topics from geology and botany to kindergarten education.

“During the [American] Civil War the exercises of the University [of Mississippi in Oxford] were suspended, and Hilgard… was placed in charge of the library and equipment by the governor and thus escaped service in the [Confederate] army.” (6)  While Hilgard probably had little time to devote to botany during those years, and he usually did not write specific location information beyond “S. Miss.” (southern Mississippi) on his specimens, NCU  does have three specimens Hilgard collected in 1866 that specify that they were collected from Oxford, Mississippi.

Eugene Hilgard was born in Zweibrucken, Germany on 5 January, 1833, the youngest of nine children, to Theodore Erasmus and Margareth Hilgard.1,3,6  Theodore Erasmus Hilgard, “held for a number of years the position of chief justice of the court of appeals (supreme court) of [Rhenish Bavaria].  [Theodore] was a prominent Liberal in the most liberal province of Germany, and, chafing under the reactionary tendencies and measures that had become especially rampant after the futile attempt to overthrow them, made by some of the hot-headed youth at Frankfort-on-the-Main in 1833, he conceived the purpose of transplanting his large family to the United States, where he hoped to find the ‘ideal republic’ realized. Despite brilliant offers of advancement from the government, he carried out this purpose in the autumn of 1835, accompanied by numerous testimonials of regret and esteem of from his constituents, and carrying a letter from General Lafayette commending him to the good offices of the American people…Landing at New Orleans on Christmas day [1835], after a long passage of 62 days [from Havre, France], the family proceeded up the Mississippi, which was running with heavy ice, to St. Louis, and thence to Belleville, Illinois, where [Theodore] purchased a farm already well developed, which remained the family residence for many years… Schools at the time were few and primitive in that region; hence [Theodore’s children] received instruction from [Theodore], the older ones also teaching the younger; all, however, with many interruptions from participation in the work of farm and household, inevitable in pioneer life.” 1

Eugene Hilgard returned to Germany in 1849 to study at the University of Heidelberg, and graduated with honors and a doctor’s degree in 1853. Hilgard’s advisor at Heidelberg was Robert Bunsen (of “Bunsen burner” fame), and Hilgard’s thesis was entitled “Beitrage zur Kenntniss de Lichtflamme.”  While in Europe Hilgard also studied at the University of Zurich in Switzerland and at the Royal Mining School in Freiberg, Germany.  While visiting Spain he met Jesusa Alexandrina Bello, daughter of a Spanish army officer.2   Hilgard was quite a linguist and could converse fluently in German, Spanish, English, and French; he could also easily read Sanscrit, Italian, Greek, Latin, and Portuguese.”6

Hilgard returned to the United States in 1855, served as the Assistant State Geologist of Mississippi (1855-1857), then was a lecturer in chemistry at the National Medical College in Washington, D.C. from 1857-1858.5  [He] began geological exploration work in Mississippi in 1855 and was appointed state mineralogist of that State in 1858.  In 1860 he revisited Spain, married Miss Bello, and resumed his work in Mississippi in November of that year.  During the intervention of the [American] Civil War he pursued the chemical work required by the Southern Confederacy.”3  “He was appointed an agent of the Confederate ‘Nitre Bureau,’ and at the siege of Vicksburg was ordered to erect calcium lights on the bluffs for the illumination of the Federal gunboats in their attempt to pass the city.  The fleet, however, passed before he could complete the arrangements for light.”6 The University of Mississippi has a collection of Hilgard’s correspondence from his time in that state.

   “In 1866 he was chosen professor of chemistry in the University of Mississippi – the professor of geology, zoology and botany.  In 1872 he left Mississippi to take a position on the faculty of the University of Michigan [Ann Arbor, Michigan], but remained there only two years, when he was called by the Regents of the University [of California, Berkeley], to California in 1874… His  work in the investigation of soils in connection with their native vegetation, of the influence of climate on the formation of soils and especially of the nature of ‘alkali soils’ and their reclamation, a problem quite new not only in this country but in other arid regions, achieved for him a reputation as wide as the world of science.”3  From 1881 to 1883 he was a member of the Northern Transcontinental Survey.  He was a Professor of Agricultural Chemistry and Founder & Director of the State Agricultural Station from 1875 to 1904.  Hilgard is best remembered for his contributions to soil science. The mineral hilgardite (Ca2B5O9Cl·H2O) was named in his honor.7

Eugene and Alexandrina Hilgard had three children.  His son died in 1889 and Alexandrina died in 1893.  Two daughters, Marie Louise Hilgard and Alice Hilgard survived him.

Hilgard died in Berkeley, California.  University of California, Berkeley President Benjamin Ide Wheeler remarked at the memorial service for Eugene Hilgard on January 30, 1916: “We are met here today as a community of scholars, whose eldest brother, having finished his long toil under the conflict of day and night, has gone peacefully out into the perfect light.  We are met, not to bid him farewell, but to be reminded of him, to rejoice in his triumph, to reaffirm our love toward him, and thereby to quicken with one another the spiritual bonds of our guild.  Eugene Woldemar Hilgard has kept the faith.  He has lived among his fellow men in active respect for the principles of order and authority.  He has built his life into one of the most helpful institutional forms of human society.  He has fulfilled the best traditions of a refined and honourable family of the Rhenish Palatinate, out of whose stock he came.  He has been a gentleman.  He has been true to the best methods and standard of the science in whose fields he toiled.  He has been loyal to the best traditions and standards of academic life.  He has kept the faith.”2

Eugene Hilgard’s brother, Julius Erasmus Hilgard (7 January 1825-1890), was also a scientist.  Julius studied civil engineering and went on to become the Chief of the Bureau of the Coast Survey in Washington, D.C.  He was a delegate to the International Metrical Commission in Paris in 1872.4
