79117 Brydonejack           Discovered 1988 Aug. 16 by C. S. Shoemaker and E. M. Shoemaker at Palomar.
William Brydone Jack (1817-1886) was a pioneer of Canadian astronomy. He built British North America's first astronomical observatory in 1851. Jack practised public outreach in astronomy. He determined Canada's first longitude readings, delivered the first engineering lecture and created the first engineering chair in Canada.
