John Edward Geake (22 April 1925 – 3 June 1998) was a British astronomer, noted as a lunar scientist, and scientific instrument designer.
One of his interests was in trying to gain information from the polarization of light scattered from the surfaces of solid bodies in the Solar System.
It was continued by Tom Gehrels of the University of Arizona; where Geake had held the post of adjunct professor.
[4] He designed the "UMIST Refractometer" subsystem for the Cassini–Huygens probe, which reached Saturn's moon Titan after his death in 2004.
[citation needed] The main-belt asteroid 9298 Geake, discovered by Edward Bowell at Anderson Mesa Station in 1985, was named in his honour.
