Gateways towards quasicrystals

The experimental discovery of quasicrystals by D Shechtman, D Gratias, I Blech, and J W Cahn in 1984 provided the paradigm for a new type of long-range order of solid matter in nature. This discovery stimulated an explosion of new experimental and theoretical research. In years prior to the discovery, there was a very active development of various gateways to quasicrystals in theoretical and mathematical physics. Without this conceptual basis, it would have been impossible to grasp and explore efficiently the structure and physical properties of quasicrystrals. The aim in what follows is to give a non-technical and condensed account of the conceptual gateways to quasicrystals prior to their discovery.
