KLAUS D. TIMMERHAUS, professor of chemical engineering at the University of Colorado, Boulder, for 42 years, associate dean for more than 20 years, and coauthor of the widely used textbook Plant Design and Economics for Chemical Engineers (New York: McGraw-Hill), died on February 11, 2011. He was 86.
Known as “Tim” to friends and colleagues and “Dr. T” to his students, Klaus was born into a German-speaking home in Minneapolis, Minnesota, on September 10, 1924. He learned English starting in the first grade, and ultimately graduated as valedictorian of Palatine High School in Illinois, where he won three letters in track, served as a student editor, and was elected student body president.

After serving in the U.S. Navy during World War II as a radar specialist in Corpus Christi, Texas, he continued his education at the University of Illinois, where he earned three degrees and graduated with a Ph.D. in chemical engineering in 1951. He worked as a project design engineer for two years at Standard Oil of California Research Corporation, before joining the University of Colorado faculty. He was appointed
