On even the worst days, when nothing was working at the lab, I knew that at home I would find warmth, peace, companionship, and encouragement. As a consequence, the next day would surely be better.
During this period, with a series of excellent students, we further studied hyperon decays.
I was much involved in the development of the spark chamber as a practical research tool.
One of the greatest joys in my life was giving a lecture in French at the College de France.
My primary and secondary education was provided by the Highland Park Public School System.
