The University of North Carolina Herbarium has
databased approximately 4,000 specimens that were
collected by John G. Haesloop. Virtually all of those specimens were
co-collected with Harry E. Ahles. Ahles, one of the
authors of the Manual of the Vascular
Flora of the Carolinas, did not know how to drive a car. Therefore, he usually had a graduate
student accompany him on collecting trips throughout North and South Carolina
during the 1950’s. This assistant not
only drove, but also served as field assistant. Haesloop was one
of Ahles’ most frequent botanical companions.
Haesloop was born to Dietrich H. and Mary G. Haesloop in Greensboro, Guilford County, North
Carolina. His father was a civil
engineer in a steel company. Haesloop earned his B.S. from Guilford College in
Greensboro, North Carolina in 1951. Haesloop earned
a Masters degree in 1954 from the University of
North Carolina at Chapel Hill under the direction of Dr. Victor A. Greulach. He then
served in the United States Army Chemical Corps for two years before
returning to Chapel Hill. He earned
his Ph.D., again under Dr. Greulach at UNC-Chapel
Hill, in 1960.
He joined the faculty of Pfeiffer College (now
Pfeiffer University) in Misenheimer, Stanly County,
North Carolina in 1960. In addition to
teaching biology and botany, he served as a dean and vice president for
academic affairs (1974-1980), and was interim president of the College in
1978. He retired from Pfeiffer
University in 1994.
