"Calutron Girls -- Gladys Owens (foreground), one of the workers monitoring 'Calutron' mass spectrometers at the Y-12 uranium isotope separation and enrichment plant. Like many of these women, she did not realize the significance of her work in the development of the first atomic bomb until long after the war had ended."
