It is with great sadness that we announce the death from brain cancer Dr. Jeffrey K. Wagner, passed away July 8. He received a Bachelor of Science in astronomy from Penn State University in 1974 and a Ph.D. in geology and planetary sciences from the University of Pittsburgh in 1980. Wagner was a Professor of Astronomy and Geology at Bowling Green State University Firelands College for 30 years. Jeff’s name is familiar to everyone in the field of spectroscopy of planetary surfaces. His seminal work on the ultraviolet reflectances of planetary materials, which formed his Ph.D dissertation, opened a new field in planetary spectroscopy. He was the author of the book “Introduction to the Solar System,” which was published in 1991 and often used in the classroom by his students.
