David W. Green, New Glarus, Wisconsin, passed away unexpectedly on June 13, 2019, in Passau, Germany, while on a cruise on the Danube River with his wife, Susan (LeVan).

Dave was born in Beckley, West Virginia, on March 13, 1944, to Bernard and Alberta Green. He attended Marsh Fork High School, earned a B.S. and M.S. in Wood Science from West Virginia University and a PhD in Wood Science from Syracuse University of New York (SUNY). While in college, Dave served in the U.S. Army Reserves for 5 years. He moved to Canada to work for Domtar on special research projects on paper and lumber. In the evenings, Dave completed his PhD dissertation, earning his PhD in early 1978.
