Hewish, Anthony (1924–)
English radio astronomer who, in collaboration with Martin Ryle,
published the first four Cambridge Radiosource Catalogues; he also
developed, at Cambridge's Mullard Observatory in the 1960s, a special radio
telescope that was sensitive to rapid fluctuations (scintillation) in radio
sources due to disturbances in ionized gas in Earth's atmosphere, within
the Solar System, and in interstellar space. Using this instrument, his
student Jocelyn Bell Burnell discovered
the first pulsar in 1967. For this discovery
and his other work on radio astronomy, Hewish shared with Ryle the 1974
Nobel Prize in Physics.
