Biographical Sketch of Alfred O. C. Nier (1911-1994)

Alfred Otto Carl Nier, world-renown physicist and scientific instrument designer, was born in St. Paul, Minnesota, on May 28, 1911. The son of German immigrants, he became interested in science at an early age and experimented with radios during his years as a student at Humboldt High School where he graduated in 1927.

With the exception of two brief periods totaling less than five years, Nier spent his entire career at the University of Minnesota. He enrolled in 1927 at the age of sixteen and received a B. S. Degree in electrical engineering in 1931. Nier commuted to the University on the street car, traveling from the far side of St. Paul. In his sophomore year he was singled out by Physics Department chair Henry Erikson after Nier scored one hundred percent on his first three physics quizzes. In the poor employment environment of the Great Depression, Nier opted for graduate school and received a M. S. in electrical engineering in 1933 and a Ph. D. in physics in 1936.

The modest Nier always maintained that he was often "...at the right place at the right time." While a doctoral student he worked as a teaching assistant and came under the tutelage of Professor John Tate, nationally-known physicist and editor of The Physics Review. Nier began working with an early version of the mass spectrometer, the instrument that became the essence of his professional life. He incorporated the work that had gone before him and created the highest resolution instrument anywhere in the world. From this point on Nier dominated the field of mass spectrometry until his death in 1994. His doctoral work led him to the first quantitative measurement of argon isotopes and to the discovery of the potassium 40 isotope in the spring of 1935.

The potassium discovery was significant in his receiving a two-year National Research Council post doctoral fellowship which he carried out at Harvard University. There Nier continued to work with the mass spectrometer and abundance of isotopes research. He was particularly interested in geochronology and the decaying of uranium isotopes to form lead.

Nier returned to Minnesota in 1938 to an assistant professor appointment in the Department of Physics. Harvard allowed him to keep his mass spectrometer tubes, and he assembled a new instrument. At the American Physical Society meeting in Washington in the spring of 1939 Nier's friend, Columbia University Professor John R. Dunning, introduced him to recent Nobel Prize winner Enrico Fermi, who encouraged Nier to use his mass spectrometer in the quest to determine which uranium isotope was responsible for slow neutron fission.

When Nier had not produced any results by October, Fermi wrote Nier the now-famous letter suggesting that the mass spectrometer was "...the best way to decide the question, which is of considerable theoretical and possibly practical interest."

Nier took Fermi's advice; and on February 29, 1940, mailed to Dunning for verification the minuscule samples that demonstrated that uranium 235 was the fissionable isotope. Nier's mentor, Professor Erikson, noted this research in his journal and observed with rather incredible understatement," This gave rise to a great interest."

Nier's U235 discovery placed him within a highly-charged scientific and political atmosphere, and by the end of 1940 his work had become classified. By the summer of 1942 the University had relieved him of teaching duties so that he could concentrate on research financed by the U. S. Government's Office of Scientific Research and Development. Together with his talented technician, Rudolph (Buddy) Thorness, Nier built seven more mass spectrometers for uranium analysis and nine for hydrogen-deuterium analysis. He also designed and built four instruments to be used as helium leak detectors. One of the leak detectors became the General Electric prototype for the manufacture of hundreds of machines crucial to the Manhattan Project during World War II.

Between the summer of 1943 and the fall of 1945 Nier worked on the Manhattan Project at the Kellex Corporation in laboratories located in the vicinity of Columbia University and his friend Dunning and another well-known Manhattan Project scientist, Eugene Booth. Kellex built the gas diffusion plant at Oak Ridge, Tennessee, to collect the U235 used in the atomic bomb. Nier designed the mass spectrometers for process control at the plant.

After Nier returned to Minnesota in the fall of 1945, he assumed a heavy teaching load; but he also continued to develop mass spectrometers and to revolutionize atomic measurement. His research focused on measuring the atomic masses of most of the elements in the periodic table. He applied his instrumentation to other fields--geology, meteorology, and medicine. Together with Edgar Johnson he developed a double-focusing mass spectrometer which became famous for its Johnson-Nier geometry.

The University of Minnesota promoted Nier to full professor in 1944; and after he spent a brief period as acting chair he became Chair of the Physics Department in 1953, serving until 1965. In this role he concentrated on hiring outstanding faculty and on improving science education in the public schools. In 1965 the University appointed Nier a Regents' Professor, the highest honor bestowed upon a faculty member. Nier also participated in the University Senate and its committees. In 1966-1967 he chaired the Senate Consultative Committee in its search for a new University President. During this period he also traveled extensively, many times to laboratories in foreign countries.

During the late Fifties Nier became acquainted with Rudolph Bieri and Peter Signer, two European scientists who came to the University of Minnesota as postdoctoral researchers. They stirred Nier's interest in meteorite research. From meteorites he progressed to space science, a focus that continued for thirty-five years.. Beginning in 1960 he became active on committees of the National Academy of Sciences, Space Sciences Board. In 1964, working with the Naval Research Laboratory, he began experiments with Aerobee Rockets and developed small mass spectrometers for upper atmosphere analysis.

Nier's grants from the National Aeronautics and Space Administration led to the development of prototype instruments for the Viking Mars and Pioneer Venus missions. Under a NASA contract in the early Seventies he developed instruments and performed data processing for the Atmospheric Explorer Satellites C, D, and E.

In 1970 NASA selected Nier to head the Entry Science Team for the Viking mission to Mars. When the Viking lander set down on July 20, 1976, a Nier-designed mass spectrometer detected the presence of argon and nitrogen in the Martian atmosphere, a significant discovery of the mission. Nier also served as a member of the Molecular Analysis Team in the Viking program.

Simultaneous with his intense research activities Nier was active on several national boards. He was appointed to the National Bureau of Standards Panel for the Analytical Chemistry Division. He chaired the National Research Council Board of Fellowships and Associateships and served on the editorial board of Science, published by the American Association for the Advancement of Science. The National Academy of Sciences named Nier to chair an ad hoc committee, requested by the U. S. Arms Control and Disarmament Agency. The committee operated as a workshop; and on October 4, 1975, issued its report entitled "Long-Term Worldwide Effects of Multiple Nuclear-Weapons Detonation." The cautious optimism of the report stirred considerable controversy in the press.

Nier also participated in a number of international programs including COSPAR, the Committee on Space Research established by the International Council of Scientific Unions, and COESA, the Committee on Extension of the Common Atmosphere. Working with the Atomic Weights Commission, the International Union of Pure and Applied Chemistry (IUPAC), and the International Union of Pure and Applied Physics (IUPAP), Nier became a principal promoter of the successful efforts to establish Carbon 12 as the common standard for measurements in chemistry and physics.

Professional memberships also demonstrate Nier's devotion to scientific endeavor. The focus of his participation varied with his changing research interests; and he became involved in a number of organizations including the American Society for Mass Spectrometry, the Geochemical Society, the Geological Society of America, the American Geophysical Union, the American Vacuum Society, Sigma XI, and the Meteoritical Society.

Nier officially retired from the University of Minnesota in 1980; but he continued a full-time research program, working closely with his assistant, Dennis Schlutter. Nier's research interests shifted once again, this time to extraterrestrial materials; and he conducted many mass spectrometer experiments to analyze interplanetary dust particles, also known as cosmic dust. He continued to maintain his many professional contacts and his attendance at conferences. Nier died on May 16, 1994, from injuries suffered in an automobile accident on the way home from his laboratory. Just a few days shy of his eighty-third birthday, he was still under contract with the Los Alamos National Laboratory. During Nier's sixty-year career his intense curiosity and persistent hard work drove him to contribute 218 publications to refereed journals and to design countless mass spectrometers.

Throughout his long career Nier collected many honors and awards. He was elected to the National Academy of Sciences in 1950 and to the American Philosophical Society in 1953. In 1956 the Geological Society of America awarded him its Arthur L. Day Medal for his work with geochronology. In 1959 he was elected as a Foreign Scientific Member of the Max-Planck Institute for Chemistry (Otto Hahn Institute) in West Germany. NASA honored him twice--with a Medal for Exceptional Scientific Achievement in 1977 and a posthumous Public Service Medal in 1995. In 1980 he was elected to the American Academy of Arts and Sciences and to the Royal Swedish Academy of Science. He won the Geochemical Society's Viktor M. Goldschmidt Medal in 1984, the American Chemical Society's Field and Franklin Award in 1985, the International Mass Spectrometry Conference's Thomas Medal in 1985, and the American Geophysical Union's William Bowie Medal in 1992. In 1995 the Commission on New Minerals and New Mineral Names of the International Mineralogical Association honored Nier posthumously by designating "Nierite" as a new trigonal silicon nitride.

Collection Scope and Content Note

The Nier Collection reveals the life and work of a remarkable person devoted to scientific research and propelled by insatiable curiosity. Although Nier did not devalue practical applications of scientific research, he was an enthusiastic advocate of pure science or as he often phrased it,"curiosity-based research." Nier believed that new knowledge was essential to the life of a university and that basic science was crucial to the development of industry and essential to the national defense.

Throughout a career that stretched to nearly sixty years, Nier faced a series of historical challenges which greatly affected his research: the discovery of atomic energy and the subsequent nuclear age, the necessity for grantsmanship, the advent of the computer revolution, and the adventure of space exploration. He excelled in meeting these challenges and thrived on them.

Nier's early education in electrical engineering became a crucial factor in his success in the design of precision instruments. Although Nier did not originate the concept of the mass spectrometer, he was foremost in its development, guiding it from a clumsy two-ton laboratory instrument to a miniature model carried easily on spacecraft.

Although Nier was first and foremost a physicist, his mass spectrometers quickly led to crucial intersections with other scientific fields. He himself expanded into geology to study geochronology; and his instruments assisted other researchers in medicine, pharmacology, and botany as well as chemistry and engineering. The industrial application of his instrument designs was also very significant.

In his devotion to scientific research, Nier valued his professional and personal relationships. He maintained a genuine interest in the research of others and made countless visits to laboratories, institutes, and conferences, both in the United States and abroad. He was a confident scholar who avoided even a hint of arrogance, and he truly understood the value of maintaining his correspondence and writing "Thank you" notes. He willingly shared his ideas in order to stretch the boundaries of scientific inquiry.

Nier's papers also reveal a person concerned with the historical record of scientific accomplishment. As early as the 1950's he consulted with the University of Minnesota Archives to insure the proper preservation of materials from the Department of Physics. He went to great lengths to preserve his U235 mass spectrometer in the Smithsonian Institution. He often spoke on the history of the mass spectrometer and many times wrote memorial biographies of his scholarly colleagues.

Detailed Contents of Collection

Location		Title
		Correspondence, 1937-1994. (9 boxes)   Note The CORRESPONDENCE Section contains a large number of folders, mainly relating to the Post World War II phase of Nier's life. Most of the folder titles refer to persons, but he also filed a number of items under subject headings. The correspondence folders may also include reports, reprints, and other items related to the correspondence. Folders are arranged alphabetically, and the items within the folder are arranged chronologically. At the end of each of alphabetical section there is a folder containing assorted correspondence for that letter, for materials that did not merit their own folder. Materials within these folders are arranged alphabetically and in turn chronologically within a given topic. Sometimes, these entries reveal a rather creative Nier logic, for example the placement of correspondence with a Canadian scientist under "A" for Alberta. If the researcher is looking for correspondence with a particular person or a particular subject these general folders should be consulted. The Correspondence Section is particularly significant in demonstrating Nier's relationship with other scientists. The John Dunning folder (Box 2) is crucial to the story of the isolation of U235 during February and March of 1940. These are materials that were long thought to be unavailable until John R. Dunning, Jr., provided them to Nier in the fall of 1989. This folder also contains the famous Fermi Letter of October 28, 1939. Other significant correspondents include Gregory Baxter, Kenneth Bainbridge, and Arthur Holmes, all associated with Nier's work while at Harvard. Nier's exchanges with Austrian scientist Joseph Mattauch reveal a close professional and personal friendship, which lasted over several decades. Although the majority of the correspondence is included here, other sections of the collection also include correspondence. This is particularly true of the National Aeronautics and Space Administration correspondence, found with the NASA papers in Boxes 20 and 21.

		Space Research   Note The space-related research materials comprise a large part of the Nier Collection, reflecting a period of roughly thirty-five years. There is considerable material on early rocket flights (Boxes 21 and 22) and the ATMOSPHERIC EXPLORER Satellites (Boxes 13 and 14 plus two flat boxes), including papers from the Atmospheric Explorer Working Group. The VIKING materials, Boxes 15, 16, 17, and 18, reflect Nier's chairmanship of the Entry Science Team for the Mars landings and the crucial experiments that revealed the presence of argon and nitrogen in the Martian atmosphere. Box 18 also contains a limited amount of material on COMETS and on the PIONEER VENUS Satellite. The Atmospheric Explorer materials and the Viking materials are arranged chronologically; other space science materials are arranged alphabetically within each division. Within the space science materials there are several folders, primarily involving government grants and contracts, that are arranged in business fashion with the most recent item appearing first. Nier's later research interests shifted to EXTRA-TERRESTRIAL MATERIALS and focused on the study of interplanetary dust particles (IDP's) and meteorites, materials found in Box 19. Notes and an outline for his final paper are found in the folder titled "Symposium in Inorganic Mass Spectrometry" found in the Correspondence Section in Box 8. The paper, "The Record of Solar Corpuscular Radiation Preserved in Lunar Soil," was to have been given at the Second Alfred O. Nier Conference at the Tamarron Center in Durango, Colorado, in May, 1994. Nier's accident prevented his attendance. His final publication, "Helium and Neon in Lunar Ilmenites and Different Antiquities was accepted by the journal Meteoritics before his death. It can be found in the Extraterrestrial Materials papers in a folder labeled "Lunar Ilmenites Paper" found in Box 19.
