Rosemary Fowler

Rosemary Fowler is a British physicist who in 1948 as a 22-year-old doctoral researcher discovered the kaon. While studying photographic plates that had been left exposed to cosmic rays, she identified a new configuration of tracks within the photographic emulsion that she recognised as being the decay of an unknown charged particle. Her discovery contributed to the introduction into particle physics of the property of strangeness, and to physicists' understanding that parity is not conserved in weak interactions – features that now form an integral part of the Standard Model of particle physics.
