Biographical Note

Edgar Theodore Wherry was born on September 10, 1885, in Philadelphia, Pennsylvania. After graduating from the Friends Central School in 1902, he received a scholarship to the University of Pennsylvania, where he earned a Bachelor’s Degree in Chemistry in 1906 and a Ph.D. in Geology-Mineralogy in 1909.

He taught for five years as an assistant professor in the Geological Department of Lehigh University. In 1913, he became the assistant curator of mineralogy at the U.S. National Museum in Washington, D.C. During his time in Washington, he began working with the Wild Flower Preservation Society and taught himself the principles of botany. He started exploring theories of soil chemistry in relation to plant growth.

Dr. Wherry’s work with ferns and their “relationship to their geological-chemical environment” became the topic of many of his publications, and the focus of his membership and subsequent presidency of the American Fern Society from 1934 to 1938. Wherry published three key guides to the ferns of North America: Guide to Eastern Ferns in 1937,  The Fern Guide in 1961, and  The Southern Fern Guide in 1964.

Wherry was a professor of botany at the University of Pennsylvania from 1930-1955, and in 1932 he was appointed ecologist to the Morris Arboretum. He also taught soil science, plant physiology, plant ecology, and taxonomy at the Arboretum School of the Barnes Foundation from 1941 to 1950, and again from 1953 to 1957.

He is credited with discovering the mineral Wherryite, as well as several plants, including Asplenium xtrudellii,  Microgramma heterophylla,  Sarracenia oreophila, and  Sarracenia jonesii. Plants named in honor of Dr. Wherry include  Tiarella wherryi,  Spilene wherryi , and  Dryopteris wherryi.

Wherry was awarded professor emeritus status upon his retirement from University of Pennsylvania in 1955. He was also awarded the Mary Soper Pope Medal by the Cranbrook Institute of Science in 1964 for his achievements in plant research.

Dr. Wherry worked closely with many botanical organizations, such as the Bowmanes Hill State Wild Flower Preserve, the American Rock Garden Society, the Delaware Valley Chapter of the American Rock Garden Society, and the Delaware Valley Fern Society.

The writings series includes drafts of articles, a glossary of terms, and identification keys created by Dr. Wherry and others. Drafts are generally corrected typescript or carbon copies, and notes are generally in manuscript. Some writings are in the form of clippings from journals, and some in complete journal issues. Subjects include phlox, ferns, shale-barrens, and wild flowers.

The reprints series includes journal articles collected by Dr. Wherry for research, a biography of Dr. Wherry, his doctoral thesis, and reprints identified as “give aways.” Subjects include, ferns, phlox, polemoniaceae, shale-barrens, rock gardens.
