Martin Ryle
Sir Martin Ryle (27 September 1918 – 14 October 1984) was an English radio astronomer who developed revolutionary radio telescope systems (see e.g. aperture synthesis) and used them for accurate location and imaging of weak radio sources. In 1946 Ryle and Derek Vonberg were the first people to publish interferometric astronomical measurements at radio wavelengths. With improved equipment, Ryle observed the most distant known galaxies in the universe at that time. He was the first Professor of Radio Astronomy in the University of Cambridge and founding director of the Mullard Radio Astronomy Observatory. He was the twelfth Astronomer Royal from 1972 to 1982. Ryle and Antony Hewish shared the Nobel Prize for Physics in 1974, the first Nobel prize awarded in recognition of astronomical research. In the 1970s, Ryle turned the greater part of his attention from astronomy to social and political issues which he considered to be more urgent. He was also an enthusiastic amateur radio operator (callsign G3CY).
Martin Ryle was born in Brighton, England, the son of Professor John Alfred Ryle and Miriam (née Scully) Ryle. He was the nephew of Oxford University Professor of Philosophy Gilbert Ryle. Martin had four siblings, and at first was educated at home by a governess. After studying at Bradfield College, Ryle studied physics at Christ Church, Oxford. In 1939, Ryle worked with the Telecommunications Research Establishment (TRE) on the design of antennas for airborne radar equipment during World War II. After the war, he received a fellowship at the Cavendish Laboratory.
The focus of Ryle's early work in Cambridge was on radio waves from the Sun. His interest quickly shifted to other areas, however, and he decided early on that the Cambridge group should develop new observing techniques. As a result, Ryle was the driving force in the creation and improvement of astronomical interferometry and aperture synthesis, which paved the way for massive upgrades in the quality of radio astronomical data. In 1946 Ryle built the first multi-element astronomical radio interferometer.
Ryle guided the Cambridge radio astronomy group in the production of several important radio source catalogues. One such catalogue, the Third Cambridge Catalogue of Radio Sources (3C) in 1959 helped lead to the discovery of the first quasi-stellar object (quasar).
While serving as university lecturer in physics at Cambridge from 1948 to 1959, Ryle became director of the Mullard Radio Astronomy Observatory in 1957 and professor of radio astronomy in 1959. He was elected a Fellow of the Royal Society (FRS) in 1952, was knighted in 1966 (p 519 of) and succeeded Sir Richard Woolley as Astronomer Royal from 1972 to 1982. Ryle and Antony Hewish shared the Nobel Prize for Physics in 1974, the first Nobel prize awarded in recognition of astronomical research. In 1968 Ryle served as professor of astronomy at Gresham College, London.
According to numerous reports Ryle was quick-thinking, impatient with those slower than himself and charismatic. He was also idealistic, a characteristic he shared with his father. In an interview in 1982 he said "At times one feels that one should almost have a car sticker saying 'Stop Science Now' because we're getting cleverer and cleverer, but we do not increase the wisdom to go with it."
He was also intense and volatile, the latter characteristic being associated with his mother. The historian Owen Chadwick described him as "a rare personality, of exceptional sensitivity of mind, fears and anxieties, care and compassion, humour and anger."
Ryle was sometimes considered difficult to work with[citation needed] – he often worked in an office at the Mullard Radio Astronomy Observatory to avoid disturbances from other members of the Cavendish Laboratory and to avoid getting into heated arguments, as Ryle had a hot temper. Ryle worried that Cambridge would lose its standing in the radio astronomy community as other radio astronomy groups had much better funding, so he encouraged a certain amount of secrecy about his aperture synthesis methods in order to keep an advantage for the Cambridge group. Ryle had heated arguments with Fred Hoyle of the Institute of Astronomy about Hoyle's steady state universe, which restricted collaboration between the Cavendish Radio Astronomy Group and the Institute of Astronomy during the 1960s.[citation needed]
