Charles Angas Hurst AM DSc FAA (22 September 1923 – 19 October 2011) was an Australian mathematical physicist noted for his work in lattice models, quantum field theory, asymptotic expansions and Lie groups. He was appointed a Member of the Order of Australia in 2003, elected a Fellow of the Australian Academy of Science in 1972, and awarded the Centenary Medal and an Hon DSc (Melb). His PhD was a seminal work on quantum field theory, developing asymptotic expansions for perturbation expansions. In 1952 Hurst represented Australia in the inaugural International Mathematical Union.
