The Manhattan Project

To Fermi ~ with Love - Part 1

Fermi: The event that took place in this room ten years ago would not have seemed in any way spectacular to a casual observer. You would have seen a large black graphite structure, of which there is a scale model, supported in part by a scaffolding of wooden beams. You would have seen a number of people reading instruments and recording their results. Perhaps you might not even have noticed many signs of excitement in their faces because the experiment in which the first self-sustaining chain reaction was obtained had been preceded by a great number of other tries.

Lew Kowarski's Interview - Part 1

Kowarski: So born in Leningrad, February, 1907. Father, businessman. Mother had a little career of her own as a singer, but [inaudible]. Father, his business started to be paper, pulp and paper, and then from that he branched off to supplying paper to newspapers and magazines, and from there he branched off into participation in magazines.

Clarence Larson

Dr. Clarence Larson, a chemist, began working under Ernest Lawrence in his lab at the University of California, Berkeley in 1942. While Lawrence and his team were engineering the cyclotron, Larsen was on hand to ensure chemical processing was sound. His primary concern was not the cyclotron itself, but its product and the ability of that product to produce an explosion.
