Ian Stewart Glass (born 5 September 1939 in Dublin, Ireland) is an infrared astronomer and scientific historian living in Cape Town, South Africa.
[17] The most detailed image of the Galactic Centre (inner Bulge) region before the advent of array detectors was obtained with Catchpole and Whitelock in 1987,[18] showing up extinction patterns that correlated with the intervening molecular clouds.
"Revolutionaries of the Cosmos" deals with eight figures (Galileo, Newton, Herschel, Huggins, Hale, Shapley, Eddington and Hubble) who revolutionised physical astronomy through the introduction of radical new ideas and techniques.
"Nicolas-Louis de La Caille" concerns the leading observational astronomer of the mid-eighteenth century who was also the first important scientist to visit what is now South Africa (1751–53).
Glass received the Gill Medal[3] of the Astronomical Society of Southern Africa in 1999 for his work in the infrared and their McIntyre Award in 2003 for his book on the Grubb Telescope Company (see below).
