15045 Walesdymond           Discovered 1998 Dec. 10 by Spacewatch at Kitt Peak.
William Wales and Joseph Dymond were two young Yorkshire men sent to the shores of Hudson Bay by the Royal Society of London to observe the transit of Venus on 1769 June 3. They stayed for over a year at Fort Prince of Wales, near modern-day Churchill, Manitoba.
