"In his last illness, Mr. Ashe wrote to Mr. Harbison, asking him in case of his death, to assist Mrs. Ashe in disposing of the Ashe Herbarium, and also expressed the hope that it could be secured by the University of North Carolina. It must be a considerable satisfaction to botanists everywhere that Mr. Harbison's own collection at Highlands has also since his death been secured by the University of North Carolina, and that the private collections of both of these men are to be found together in the same Herbarium, where they will continue to assist the present and later botanists in a way comparable to the assistance their collectors so freely gave to others while in life."Coker, Totten, & Oosting in Harbison's obituary
Thomas Grant Harbison was born in Union County, Pennsylvania on April 23, 1862. He attended college during vacations, never actually being registered for a continuous year. Most of his classes were taken at nearby Bucknell University, but he also took short courses at the University of Norway and the University of Leipzig. He learned much from his own reading and owned a library of over one thousand volumes by the time he was twenty-one. He earned his B.S., A.M., and Ph.D. degrees through correspondence courses.
A formative event in Harbison's youth was a walking tour of Maryland, Virginia, and North Carolina. They carried a bag of ground wheat and a tin of brown sugar and survived almost entirely on these rations throughout the trip. While visiting Highlands, NC on this excursion, he apparently impressed the residents with his knowledge so much that they later asked him to return as a school principal. He served in some educational capacity at Highlands from 1886 to 1896, with the exception of a trip to Europe to study educational systems in 1893-94. In 1896 he married Miss Jessamine M. Cobb, descendent of John Cobb, who built and operated the first iron foundry in America.
The botanical work for which Harbison is best known began in 1897 when he became a collector for the Biltmore Herbarium of the George W. Vanderbilt estate. He was employed in this capacity until the disbanding of the herbarium in 1903. In his next job, he worked under C. S. Sargent of the Arnold Arboretum and was charged with the collecting of southern woody plants. His association with the University of North Carolina Herbarium began in 1933 when he was asked to help organize the W.W. Ashe Herbarium. The following year he was appointed Curator of the Herbarium, a post which he held until his death in 1936. Harbison was a close friend and frequent correspondent of Ashe. Both of their herbaria are now housed at UNC.
These images represent one of Harbison's field notebooks, a letter written by Harbison to Ashe, and a specimen which he collected. The letter and the specimen may both be clicked on to view larger images. The Southern Historical Collection at UNC contains a number of letters addressed to Harbison from Charles Sprague Sargent.
Harbison was not a voluminous writer. His contributions to botany were more through teaching and collecting. His known publications are listed below:

A Sketch of Sand Mountain Flora. Biltmore Botanical Studies 1(2): 151. 1902.
Notes on the Genus Hydrangea. American Midland Naturalist 11: 255, 1928.

The bibliography and most of the above biographical information is derived from an obituary notice written by H. R. Totten, W. C. Coker, and H. J. Oosting which appeared in the Journal of the Elisha Mitchell Scientific Society, December, 1936.
