# William M. Harlow

William M. Harlow (1900–1986) was an American professor of engineering and silviculture at the SUNY College of Environmental Science and Forestry. He was also a nature photographer and filmmaker, particularly of time-lapse films.

## Education and career

Harlow was a native of Syracuse, New York. He graduated from Blodgett Vocational High School and attended the NYS College of Forestry (now SUNY College of Environmental Science and Forestry), receiving a bachelor's degree in 1925, a master's degree in 1926, and a doctorate in 1928. Harlow was a member of the faculty of the college from 1928 until his retirement in 1965, serving as an instructor, assistant professor, associate professor, and professor in the field of wood technology. He pioneered the research of wood cell wall chemistry.
He authored a number of articles on outdoor education under the pen name "Moosewood", and was a camping consultant for six years to the Rescue Mission's Camp Id-Ra-Ha-Je; in 1963, the camp renamed its main building to Moosewood Lodge. He was the head of the camping department at the Sargent College of Physical Education in Petersboro, N.H (now operated by Boston University as the Sargent Center for Outdoor Education), and taught at several other nature camps. Harlow received the Heiberg Award in 1980 from the New York Forest Owner's Association, and the College of Environmental Science and Forestry's Alumni Association Distinguished Achievement Award in 1984.

## Publications and research interests

Harlow wrote seven books. His Textbook of Dendrology is in its sixth edition and has sold more than 120,000 copies. The book focuses on tree identification and characteristics. Other books by Harlow include Trees of Eastern and Central United States and Canada, which sold more than 100,000 copies, and Art Forms from Plant Life, Inside Wood and Ways of the Woods.

His color enlargements can be found in the Life Nature Library Books The Forest and The Scientist, as well as in McGraw-Hill's Life of the Forest and Life of the Marsh. He also illustrated textbooks for other publishers, and sets of slides have been distributed by Ward's Natural Science of Rochester.
