Richard Taylor. Portrait of the Canadian particle physicist Richard Taylor (born 1929). Taylor became interested in physics after the atomic bombs ended World War Two. He was educated at the University of Alberta, where he gained a Master's degree. After graduating, he moved to Stanford, California, USA, and worked at the Stanford Linear Accelerator Centre (SLAC) there. In the late 1960s he worked with Jerome Friedman and Henry Kendall investigating the structure of protons and neutrons. This led to the discovery of quarks, the constituents of several subatomic particles. For this work, the trio received the Nobel Prize for Physics in 1990. Photographed in 1999.
