MAC ELWYN VAN VALKENBURG, former W.W. Grainger Professor Emeritus of the Department of Electrical and Computer Engineering and Dean Emeritus of the College of Engineering at the University of Illinois, Urbana-Champaign, died on March 19, 1997, at the age of 75. He was elected to NAE in 1973.
Mac was born on October 5, 1921, in Union, Utah, the son of Charles M. and Nora Louise Walker Van Valkenburg.
