With heavy hearts, we report the passing of Professor Emeritus Tom Bolton earlier this week.
Tom is probably best known for providing the first definitive evidence showing that Cygnus X-1 is a black hole using the David Dunlap Observatory’s telescope. He was also instrumental in drafting the City of Richmond Hill’s landmark light pollution abatement bylaw.
As a close colleague of ours, he will dearly be missed.
Please take the time to watch this TVO Science Café episode where Tom -alongside other notable DDO astronomers – explains the history of the DDO and provides a tour of the 74″ telescope (circa 1990).
