of Idaho. Combined, he has authored or coauthored 110 technical articles, eight books, and
four patents, and also coauthored the section on distillation in the sixth and seventh editions
of Perry S Chemical Engineers' Handbook. Seader was a trustee of CACHE for 33 years,
serving as Executive Officer from 1980 to 1984. For 20 years he directed the use and dis-
tribution of Monsanto's FLOWTRAN process simulation computer program for various
universities. Seader also served as a director of AIChE from 1983 to 1985. In 1983, he pre-
sented the 35th Annual Institute Lecture of AIChE; in 1988 he received the computing in
Chemical Engineering Award of the CAST Division of AIChE; in 2004 he received the
CACHE Award for Excellence in Chemical Engineering Education from the ASEE; and in
2004 he was a co-recipient of the Warren K. Lewis Award for Chemical Engineering Edu-
cation of the AIChE. For 12 years he served as an Associate Editor for the journal, Indus-
trial and Engineering Chemistry Research.

Ernest J. Henley is Professor of Chemical Engineering at the University of Houston.
He received his B.S. degree from the University of Delaware and his Dr. Eng. Sci. from
Columbia University, where he served as a professor from 1953 to 1959. Henley also
has held professorships at the Stevens Institute of Technology, the University of Brazil,
Stanford University, Cambridge University, and the City University of New York. He has
authored or coauthored 72 technical articles and 12 books, the most recent one being
Probabilistic Risk Management for Scientists and Engineers. For 17 years, he was a trustee
of CACHE, serving as President from 1975 to 1976 and directing the efforts that produced
the seven-volume set of "Computer Programs for Chemical Engineering Education" and
the five-volume set, "AIChE Modular Instruction." An active consultant, Henley holds
nine patents, and served on the Board of Directors of Maxxim Medical, Inc., Procedyne,
Inc., Lasermedics, Inc., and Nanodyne, Inc. In 1998 he received the McGraw-Hill Com-
pany Award for "Outstanding Personal Achievement in Chemical Engineering," and in
2002, he received the CACHE Award of the ASEE for "recognition of his contribution to
the use of computers in chemical engineering education." He is President of the Henley
