Carl Martin Brandauer died peacefully on October 22, 2016. He was born in Beijing, China on October 23, 1924 to Lucy Dewey and Wolfgang Brandauer. Carl spent most of his childhood in Austria. The family moved to the United States in 1938 where Carl attended the Fountain Valley School in Colorado Springs, CO. In 1943, he joined the 10th Mountain Division and was eventually deployed to Italy where he was awarded both a Purple Heart and a Silver Star. After the war he spent two years teaching climbing and skiing for the U.S. Army in Colorado Springs. In 1947 he entered Columbia University where he earned his B.A., M.A. and PhD in Experimental Psychology. From 1954 to 1982, Carl worked for Haskins Labs, Bell Labs and NCAR. He then founded Daemon Associates specializing in Unix and C language programming and training. Carl was a member of the American Alpine Club, the Sierra Club and President of the Colorado Mountain Club during the late 1960s. In 1948, Carl married Diane Marie Labalme. They had two children, Peter and Aline. He married Nancy Ellsworth Spackman in 1969 after meeting her on a Sierra Club trip that he was co-leading in Colorado's San Juan Mountains. Carl had a very deep voice and wry sense of humor. He was fascinated by any scientific question and used his razor-sharp analytical skills in many fields from psychology to systems analysis. He loved the outdoors and he spent many days with his family and friends, hiking, climbing, skiing and sailing. With his wife, Nancy, a malacologist, he developed a passion for the South Pacific and its environmental challenges. Carl's voice in the world was one of reason and tolerance and he instilled in his children the sense that one must work for social justice. He is survived by his and Nancy's six children, Peter Brandauer (Dianne), Aline Brandauer Sloan (Charles), John Spackman (Marion Wells), Tom Spackman (Laurie), Jennifer Anderson and Phoebe Clemens along with grandchildren Peter Brandauer, Lucy Brandauer, Tyler Sloan, Sarah Sloan, Theo Wells-Spackman, Toby Wells-Spackman, Eric Spackman, Julie Spackman, Emeline McHugh and great-grandson, Jack Brandauer. In accordance with his wishes, there will be no memorial service. In lieu of flowers donations may be made to: The Boulder County AIDS Project, 2118 14th Street, Boulder, CO 80302
