Pete J. Dunn

from Wikipedia, the free encyclopedia

Peter "Pete" John Dunn (* 10. November 1942 in Somerville , † 8. November 2017 in Alexandria ) was an American Mineralogist and "Museum Specialist" at the "Department of Mineral Sciences" of the Smithsonian Institution belonging to National Museum of Natural History , Washington, DC , USA .

Live and act

Pete J. Dunn was born in Somerville, Massachusetts to William K. and Ethel L. Dunn. He grew up there and in Reading , Massachusetts . Dunn served in the United States Air Force , then began studying at Salem State College (now Salem State University) in Salem , Massachusetts, graduating in 1969 with a bachelor's degree in geography and earth sciences. This was followed in 1973 with a Master of Science (M.Sc.) degree in geology and mineralogy at Boston University , where he also worked as a curator in the "Department of Geology" (from 1969 to 1972) .

In 1972 he took up a position as a mineralogist at the Smithsonian Institution - a position that he would not leave until the end of his career in January 2008. While at the Smithsonian Institution, he completed his research on Franklin's lead silicates. In 1983 he received his PhD in mineralogy / geology from the University of Delaware at Newark , Delaware , with Peter B. Leavens . The topic of his dissertation was "The lead-silicate assemblage at Franklin, New Jersey" .

During his time at the Smithsonian, Pete J. Dunn was an internationally recognized expert in the processing of minerals from museum collections, particularly that of the Smithsonian Institution. For many years he was the first point of contact for scientists who needed research material from the Smithsonian's mineral collection for their own investigations.

Pete Dunn was (including redefinitions (= Rd)) involved in the first description of over 130 minerals - from the Wroewolfeit described in 1975 to the Benauite described in 1996 . Dunn held the unofficial world record of initial descriptions for a long time - it is only in recent years that Igor V. Pekov has an even greater number of mineral initial descriptions to show. Dunn is the lead author of 59 minerals. For 66 of the 135 new minerals, he wrote the official initial description together with Donald R. Peacor .

In the course of his professional life, Dunn published more than 300 scientific papers - the first of which was “Gem spodumen and achroite tourmaline from Afghanistan” in the Journal of Gemmology 1974 - and numerous book reviews. He wrote about a dozen guest editions in the journal "The Mineralogical Record", which discussed the contributions of the mineral-collecting community and their interaction with the sciences. An important part of his work was also the systematic mineralogy and the mineral systematics, including the discrediting of wrongly described species as well as redefinitions and revalidations of incompletely described minerals, definition of solid solution rows in mineral groups and nomenclature issues.

Pete J. Dunn's mineralogical specialty was the mining district of Franklin - Sterling Hill, New Jersey. He has published over 70 scientific papers and a nine-volume monograph, "Franklin and Sterling Hill, New Jersey: The World's Most Magnificent Mineral Deposits," on the mineralogy, geology, and mining history of this famous find district . These include a five-volume mineralogical monograph, a two-volume work on mining history from 1765 to 1900 and two general books, including one for children and one for adults - all in all the ultimate work for this location for both scientists and collectors and the general public (see the compilation under "Fonts").

Another important research area for Dunn were two deposits in Namibia. From the “Tsumeb Mine” he described - mostly with Paul Keller - a total of 15 new minerals, the first descriptions for Kombatit, Asisit, Holdawayit, Ribbeit and Johninnesit come from material from the “Kombat Mine”. On the minerals of the "Kombat Mine" he also published the article "Rare Minerals of the Kombat Mine, Namibia" .

Pete J. Dunn was a voting member of the "Commission on New Minerals and Mineral Names" (CNMMN) of the International Mineralogical Association (IMA) from 1984 to December 2007 . During these 24 years he published the "Formal Definitions for Type Mineral Specimens" (1987) together with the then Chairman of IMA Joe Mandarino . With “Protocols for Scientists on the Deposition of Investigated Mineral Samples” (1988) and “The Discreditation of Mineral Species” (1990), he also initiated further IMA standards that are still used today.

He was co-editor of the “American Mineralogist” (1982–1985), the “Mineralogical Record” (1977–1993) and the “New Yearbook for Mineralogy”, monthly books (1989–1991). After leaving the Smithsonian Institution in December 2007, he returned to the museum's information desk as a volunteer in January 2008.

Honors and memberships

In 1987, Professors Eric J. Essene and Donald R. Peacor from the University of Michigan in Ann Arbor, Michigan / USA described a new zinc-containing clinopyroxene from the Franklin zinc deposit in New Jersey / USA and named it in Dunn's honor, “in recognition of his many contributions to mineralogy, particularly from Franklin and Sterling Hill, New Jersey, "as a petedunnite . "It is a very boring mineral," commented Dunn when describing this mineral in his 1995 Magnum opus . Regardless, this naming was a fitting tribute to a scientist who studied these deposits in detail and with remarkable productivity.

Dunn was a member of the "Mineralogical Society of America" ​​and the "Gemmological Association of Great Britain" as well as the "Mineralogical Association of Canada".
