During the Cold War, Swiss authorities considered the construction of a Swiss nuclear bomb. Leading nuclear physicists at the Federal Institute of Technology Zürich such as Paul Scherrer made this a realistic possibility. In 1988, the Paul Scherrer Institute was founded in his name to explore the therapeutic uses of neutron scattering technologies. Financial problems with the defence budget and ethical considerations prevented the substantial funds from being allocated, and the Nuclear Non-Proliferation Treaty of 1968 was seen as a valid alternative. All remaining plans for building nuclear weapons were dropped by 1988.
