World War II accelerated genuinely good science (penicillin, radar, jet engines, the hard maths behind early computing) alongside genuinely bad science (race-based blood storage in the US military, asbestos as a wonder material, leaded petrol still in every tank).

The decade made antibiotics. It also made the modern infrastructure of preventable disease.
