Walter Kohn — Austrian Physicist born on March 09, 1923,

Walter Kohn is an Austrian-born American theoretical physicist. He was awarded, with John Pople, the Nobel Prize in chemistry in 1998. The award recognized their contributions to the understandings of the electronic properties of materials. In particular, Kohn played the leading role in the development of density functional theory, which made it possible to incorporate quantum mechanical effects in the electronic density. This computational simplification led to many insights and became an essential tool for electronic materials, atomic and molecular structure... (wikipedia)

My commitment to a humane and peaceful world continues to this day.
I was fortunate to find an extraordinary mathematics and applied mathematics program in Toronto.
My father, who had lost a brother, fighting on the Austrian side in World War I, was a committed pacifist.
I was born in 1923 into a middle class Jewish family in Vienna, a few years after the end of World War I, which was disastrous from the Austrian point of view.
Originally I had planned to revert to nuclear physics there, in particular the structure of the deuteron.
