The Manhattan Project #OnThisDay

On 13th August 1942 The Manhattan Project started under the direction of US General Groves.

The development of an atomic bomb had been a possibility for some years as scientists explored the possibilities of nuclear fission. German chemists  Otto Hahn and Fritz Strassmann  had made headway with this in 1938. By the outbreak of war in 1939 the rush to be the first side to develop atomic weapons was on.

In 1940 Britain made their research available to the USA which had huge financial resources available for a project to develop an atomic bomb. Scientists were aware of the devastating consequences of such a weapon.
