Many students owe their later successes in life and their contributions to 
the world's welfare to inspiration and ambition derived through contact 
with Dr. Halsted in these two colleges. 
His interest centered primarily in plant pathology, and pioneer work was 
carried on regarding many fruit and truck crop diseases. He also gave 
special attention to the diseases of ornamental plants, a field in which his 
work probably overshadows that of all other contributors. While in New 
Jersey failing eyesight and health forbade further microscopic work and his 
activities were turned to field work in plant breeding. 
Dr. Halsted was a member of Phi Beta Kappa. He also won the silver 
medal of the Massachusetts Horticultural Society and was a fellow of the 
American Association for the Advancement of Science. He served in an 
official capacity many of the leading national scientific societies of the 
country. He was elected president of the New Jersey Microscopical 
Society, second vice-president of the Iowa Academy of Science in 1 888-1 889, 
secretary of Section F of the American Association for the Advancement 
of Science in 1892, secretary of the Society for the Promotion of Agricultural 
Science in 1892, and its president from 1897 to 1899, and was president of 
the Botanical Society of America in 1900-1901. He was affiliated with 
other national societies — the Society for Plant Morphology and Physiology, 
the Society of Horticultural Science, the American Society of Naturalists, 
and was associate editor of the Bulletin of the Torrey Botanical Club (1890- 
1893) and a contributor to the Systematic Flora of North America. 
Dr. Halsted was born at Venice, New York, of Quaker parentage June 
7, 1852; was thrice married and leaves three children. He died at New 
Brunswick, New Jersey, the scene of his activities of nearly thirty years, 
on August 28, 1918.
