Lew Kowarski's Interview - Part 2

Stephane Groueff: One thing I don’t understand, and it’s a very ignorant question, but what was actually the difference between [Enrico] Fermi’s experiment in ’34 and [Otto] Hahn’s? Because, why do we say that Hahn was the first one, while Fermi also bombarded uranium?

Lew Kowarski: I don’t it’s true to say that Hahn was the first one.

Groueff: It’s not true.

Kowarski: I think it’s one of those simplifications—there are people who find them all right. I don’t.
