|Name:||Named in 1973 by Sidney Arthur Williams in honor of Max Hutchinson Hey [March 11, 1904 Leyland, England, United Kingdom - January 24, 1984 Newcastle-upon-Tyne, England, United Kingdom]. Hey was a chemist and systematic mineralogist and Keeper of Minerals at the British Museum of Natural History. His several editions of Chemical Index of Mineralogy evaluated the validity of all the known published minerals and he help form the International Mineralogical Association.|
