As war raged across Europe in 1942, a team of scientists on the other side of the Atlantic were brought together to work on a top secret project – the development of an atomic bomb.
The Manhattan Project was led by the United States but a number of prominent British scientists were transferred to work on it, including Scottish physicist Sir Samuel Curran.
A new film about the development of the first nuclear weapons – Oppenheimer – follows the life of the nuclear physicist who was the director of the laboratory that designed the bombs – J Robert Oppenheimer.
Although Curran does not make an appearance in the film he was part of a team that worked on an important aspect of the project – the separation of isotopes of uranium.
The atomic bomb would not have been possible without the process, which today is called uranium enrichment.
