About

Richard D. Cannon is a pioneering figure in astronomical instrumentation and observational cosmology, best known for his instrumental role in developing the 2dF (Two-degree Field) facility at the Anglo-Australian Observatory. His key research areas encompass multi-object spectroscopy, galaxy surveys, and the engineering of large-scale astronomical instruments. Cannon's major contribution—the 2dF system—revolutionized spectroscopic surveys by enabling up to 400 target fibres to be independently positioned by a complex robot over a 2° field of view, feeding two spectrographs with resolutions from 500 to 20,000. This breakthrough allowed for the simultaneous acquisition of hundreds of galaxy spectra, dramatically accelerating the mapping of cosmic structure. His seminal paper on the facility has garnered over 350 citations, reflecting its foundational impact on subsequent surveys like the 2dF Galaxy Redshift Survey. Cannon's work exemplifies how innovative instrumentation can unlock new frontiers in astrophysics, making him a key architect of modern observational cosmology and a mentor to generations of astronomers.
