Antony Hewish (11 May 1924 – 13 September 2021) was a British radio astronomer who won the Nobel Prize for Physics in 1974 (together with fellow radio-astronomer Martin Ryle)[4] for his role in the discovery of pulsars.

[9] Returning to the University of Cambridge in 1946, Hewish completed his undergraduate degree and became a postgraduate student in Ryle's research team at the Cavendish Laboratory.

[8] For his PhD thesis, awarded in 1952, Hewish made practical and theoretical advances in the observation and exploitation of the scintillations of astronomical radio sources, due to foreground plasma.

[10] Hewish proposed the construction of a large phased array radio telescope, which could be used to perform a survey at high time resolution, primarily for studying interplanetary scintillation.

[8] In 1965 he secured funding to construct his design, the Interplanetary Scintillation Array, at the Mullard Radio Astronomy Observatory (MRAO) outside Cambridge.

In the foreword to Questions of Truth, Hewish writes, "The ghostly presence of virtual particles defies rational common sense and is non-intuitive for those unacquainted with physics.
