Jeffrey Glassberg is the founder and president of the North American Butterfly Association (NABA) and of Sunstreak Tours. Jeff has followed butterflies since he was 5 years old living on Long Island, New York. He detoured to take an undergraduate degree in civil engineering at Tufts University and a Ph.D. in molecular genetics at Rice University, then worked at Stanford University and Rockefeller University. In 1981 he invented DNA fingerprinting (this is often ascribed to Alec Jeffries, but Glassberg was issued the basic patent on this technology) and cofounded a biotechnology company (Lifecodes) that commercialized this technique.
Jeff is a past-president of Xerces Society, the author of the Butterflies through Binoculars field guide series, and the author of other books, including Butterflies of North America and (as co-author) Birds of North America. His latest book is A Swift Guide to the Butterflies of Mexico and Central America. He graduated from the Columbia University School of Law in 1993 and is a member of the New York bar. He is an Adjunct Professor of Ecology and Evolutionary Biology at Rice University.
