Louis Hempelmann's Interview - Part 4

Louis Hempelmann:  I do not think the people who came later were ever as close as the people who were there at the beginning.

Martin Sherwin: Did most of the people who came later, were they junior people? That is, younger? [Enrico] Fermi came later.

Hempelmann: [George] Kistiakowsky came later.

Sherwin: He did? When you say “earlier” and “later,” what dates are you talking about?
