Wilmot Hyde Bradley, aka "Bill" Bradley (4 April 1899 in New Haven, CT – 12 April 1979 in Bangor, ME) was a co-founder (1943) and Chief of the Branch of Military Geology and Chief Geologist of the U.S. Geological Survey from 1944 to 1959.〔(Biography by W. P. Woodring )〕 He was the son of Anna Miner Hyde and John Lucius Bradley. He attended college at the Sheffield Scientific School of Yale University and graduated from Yale in 1920 with a Ph.D. in geology, after switching from engineering and chemistry. After two years as geologic aide to Julian D. Sears〔(Open Library: Works by Julian Sears )〕 of the U. S. Geological Survey, he was taken on by the Survey to work full-time on the Eocene Green River Formation because of its oil-shale potential. As a result of his work there, the mineral "trisodium magnesium phosphate carbonate" was named Bradleyite in his honor.〔(WebMinerals: Bradleyite )〕 On the conclusion of his 48-year career with the Geological Survey in 1970, Bill and his wife retired to Pigeon Hill Bay, Maine, where he continued writing his results from years of research on the Green River Formations and Mud Lake. Bill Bradley was buried at a tiny local graveyard situated on his property at Pigeon Hill Road, Steuben, Maine. On his gravestone, he had engraved in advance the phrase, "The Earth has music for those who listen". (Although this phrase is of uncertain origin, a similar phrase -- "The Earth has its music for those who will listen"—first appeared in print in 1955 in a poem by Reginald Vincent Holmes.) ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wilmot Hyde Bradley」の詳細全文を読む スポンサード リンク
