Building on the legacy of Walter Kohn
Walter Kohn died April 19, 2016 at the age of 93.
From a childhood of unimaginable persecution, Walter Kohn rose to become a great theoretical physicist, influencing condensed-matter theory in many areas: band-structure theory, surface science, van der Waals interactions, defects in semiconductors, and more. His work inspired generations of theoretical physicists and chemists and laid the foundations for the rapid development of modern electronic structure theory. For his development of density-functional theory he was honored by the Nobel Prize in Chemistry (1998). He is the founder and father of modern computational materials science, and his impact is reflected, for example, in the figure below.

Walter Kohn and his wife Mara were a remarkable, complementary, wonderful team. We have lost a responsible, humane person, a good friend, and such a good soul.
