Name:
Named in 1964 by Richard J. Davis and Max Hutchinson Hey in honor of Sir Arthur Edward Ian Montagu Russell [November 30, 1878 Folkestone, Kent, England, UK - February 23, 1964 UK], British mineral collector and Mr Arthur William Gerald Kingsbury [June 27, 1906 East Meon, Hampshire, England, UK - August 3, 1968 UK], English mineralogists and collectors. Sir Arthur Edward Ian Montagu Russell (1878-1964) 6th Baronet, of Swallowfield Park, Reading, Berkshire, was perhaps the greatest British mineral collector of the 20th century. Sir Arthur Russell’s will directed that his collection should be given to the British Museum (Natural History) – now the Natural History Museum. The Russell Society, an organisation for amateur and professional mineralogists, dedicated to British topographical mineralogy, was named in his honor. Arthur Kingsbury, Russell's friend was an indefatigable field collector and prolific author of mineralogical articles.
