Rosemary Brown (later Fowler) 1926-. Research student in C.F. Powell's group in Bristol, following First Class undergraduate degree from Bristol. Discoverer of 'k' particle (kaon) that decayed to three pions. This "Tau" particle contrasted to the very similar "Theta" particle which had the same mass but led to two pions. The τ–θ puzzle led to the discovery of parity violation in weak interactions. Rosemary Brown married co-author P.H. Fowler.
