Robert Jay Creasy (1939-2005) was the project leader of the first full virtualization hypervisor, the IBM CP-40,〔Varian, p.10〕 which later developed into IBM's highly successful line of mainframe VM operating systems. == Biography == Creasy was born on November 15, 1939, in Honesdale, Pennsylvania. He graduated from MIT in 1961, marrying Rosalind Reeves that year. After graduation, he worked as a programmer on the CTSS timesharing system and on Project MAC. Disappointed with the direction of MAC, when he heard that Norm Rasmussen, Manager of IBM’s Cambridge Scientific Center, intended to build a time sharing system based on IBM’s System/360 and needed someone to lead the project, Creasy left MIT to join IBM. Robert and Rosalind moved to California in 1965. He retired from IBM’s Scientific Center in Palo Alto in 1993. He died on August 11, 2005, in Pioneer, California, survived by his wife, Rosalind, son Robert W. and wife Julie; daughter, Laura and husband Joel; grandson, Joel Alexander; brother, John and wife Kathy, and other relatives. 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「Robert Creasy」の詳細全文を読む スポンサード リンク
