Ian Morison FRAS (22 November 1943 – 13 April 2024) was a British astronomer and astrophysicist who served as the 35th Gresham Professor of Astronomy.

He attended Chichester High School before going on to study Physics, Mathematics and Astronomy at Hertford College, University of Oxford.

[2][3] Morison joined the University of Manchester's Jodrell Bank Observatory as a research student in 1965 before becoming a staff member in 1970.

Initially working on data acquisition systems for the observatory's own instruments including the Lovell and Mk II radio telescopes, he went on to play a key role in the development of MERLIN, an array of radio telescopes with a resolution in the radio spectrum comparable to that of the Hubble Space Telescope in the optical.

[4] On 1 August 2007, Morison was appointed as the 35th Gresham Professor of Astronomy, a position previously held by Christopher Wren.
