Nier Alfred Otto Carl Nier (May 28, 1911 - May 16, 1994) was an American physicist who pioneered the development of mass spectrometry. He was the first to use mass spectrometry to isolate uranium-235 which was used to demonstrate that 235U could undergo fission and developed the sector mass spectrometer configuration now known as Nier-Johnson geometry. ==Early career== Born St. Paul, Minnesota, Nier showed an early ability in mathematics and science, coupled with an aptitude for craft and mechanical work. Nier's German immigrant parents had little education or financial resources but their determination for his development meant that he was able to attend the nearby University of Minnesota. Though he graduated in electrical engineering in 1931, the lack of engineering jobs during the Great Depression encouraged him to take up graduate study in physics. Nier's graduate research started his involvement in mass spectrometry.〔Reynolds (1998)〕 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「Alfred O. C.
