For nearly 20 years, John Beaver has used old processes to make new negatives, often in ways that can only be realized as a print with digital scanning and printing. This includes his development of the cyanonegative process, innovative work (in collaboration with Teresa Patrick) with instant film, and most recently his development of an accelerated, unfixed printing-out process he calls (perhaps annoyingly) "Ephemeral-Process photography." He is Professor of Physics and Astronomy at the Fox Valley Campus of University of Wisconsin Oshkosh, where he teaches physics, astronomy, photography and interdisciplinary courses. He earned his B.S. in physics and astronomy in 1985 from Youngstown State University, and his PhD in astronomy in 1992 from Ohio State University. His published work in astronomy is on the topics of spectrophotometry of comets and gaseous nebulae, and multi-color photometry of star clusters. He has exhibited photographs in many juried competitions in Wisconsin, Ohio, New York, Louisiana, Missouri, Oregon and Colorado, even occasionally winning an award or two (well, two actually). He has had several soloexhibitions, as well as joint shows with artists Judith Waller, Diana Ludwig, Dawn Patel and Teresa Patrick. Beaver has long been involved in art-science collaborations (many with artist Judith Waller) in the classroom, at academic conferences, and in art galleries and planetaria.
