Hans Senn (1918–2007) was a general officer of the Swiss Army. Senn was born in Zofingen and, as a young officer, studied at the Ecole Supérieure de Guerre in Paris. As Army head of operations he unsuccessfully advocated a policy of nuclear armament as a deterrent against the Warsaw Pact in the 1960s. Switzerland eventually ratified the Nuclear Non-Proliferation Treaty.
