Alex Wiedenhoeft has contributed so much of his hard work and knowledge to the Forest Products Laboratory in the more than 20 years he has been with us. One of his most useful inventions is the XyloTron, a desktop device that provides high-resolution images of wood.

In his effort to make the XyloTron less costly and more portable, Alex also developed the XyloPhone, a small device that attaches to a smartphone and provides the same resolution as the much larger XyloTron.

In just a few months, the Xylophone has contributed greatly to the ability of scientists in the field to identify and photograph wood. But not just wood.

Artist Emily Arthur, associate professor in the UW-Madison art department, learned about the XyloPhone through her colleague Anne Pringle, professor of Botany at UW-Madison, who studies lichens and fungi in her lab. During Emily’s ongoing collaborative research with Robin Rider, curator of special collections, Memorial Library, the XyloPhone became a way to examine rare books and works on paper.

“I knew this device would be invaluable for the purposes of this research,” said Emily Arthur. “And I was right! Being able to examine the hand-colored engravings from The Birds of America at such a detailed level has revealed new information on the printing techniques that were used in its production between 1827-1838.”

The focus of the exhibit at the Chazen Museum of Art is not just the gorgeous creations of the renowned naturalist, John James Audubon, but in particular the methods that formed a tradition of exactitude in engraving that lies behind the work of printmakers like Robert Havell, Jr.
