Charles Angas Hurst (born 22 September 1923) AM, PhD, Hon DSc (Melb), is an Australian Mathematical Physicist noted for his work in Lattice models, Quantum field theory, Asymptotic expansions and Lie groups. His most famous result is probably the Griffith, Hurst, Sherman (GHS) inequalities. 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.

Hurst's work with Herbert Green[1] on lattice problems and the Ising model led to the Free fermion field model[2], which contained all known properties of Fermions at the time of its publication. Hurst's work with Thirring (Thirring model) found the simplest non-linear field and is still used as a test model for perturbation theory.
