Dick Dalitz: Examples of His Contributions to Particle Physics

Dick Dalitz produced lasting contributions to particle physics for 50 years. Along with Dalitz pairs, Dalitz plots and CDD poles, he did major work in parity violation, hyperon resonance identification, the quark model, and hypernuclei. These topics will be summarized, with some emphasis on the author's collaboration with Dalitz on quark spin and fragmentation correlations, and, particularly, the work on the identification of the top quark and its mass. Short biographical information is interspersed. This paper is based on a presentation at the International School of Subnuclear Physics, Erice 2006.
