Terry E. Huizing
(1938-    )

Terry Eugene Huizing was born in Grand Rapids, Kent County, Michigan on December 5, 1938, the son (one of four children) of Helen (née Vander Sloot) and Albert Burton Huizing, an industrial machine operator. His summer vacations while growing up were spent at Silver Lake State Park, near Mears in Lower Michigan, where his family tent-camped for weeks at a time and Terry looked for fulgurites in the sand dunes.

On the large, gravel-covered playground of Congress Elementary School in Grand Rapids, Terry was attracted to the small pebbles of brown jasper because they were so different from all the other stones. When he was about 12, the father of a neighborhood friend suggested that his son and Terry enroll in a new daily summer youth-class on rocks and minerals, to be held at the Grand Rapids Museum of Natural History. Mary Jane Dockery was the instructor, fresh out of college and eager to teach the basics of collecting. Specimens were provided, and each was to be numbered, attaching small squares cut from adhesive tape; a catalog was prepared by each of the young students, documenting the number and the identification of the specimens. They learned the difference between a rock and a mineral and recorded which they had in their catalog.

Terry graduated from Central High School in Grand Rapids in 1956, having become quite interested in chemistry in the 10th grade; this made it an easy decision to seek a degree in Chemical Engineering. Finances dictated attending the local Junior College while he worked multiple jobs to put himself through school and to build a small reserve for university. He also joining the college glee club; at a home practice session he met Marie Evelyn Moored, the sister of the pianist. They dated immediately and steadily after that time.

Terry received his Associate in Science of Engineering degree from Grand Rapids Junior College (now Grand Rapids Community College) in 1959 and went on to the University of Michigan in Ann Arbor. While completing the chemical engineering program, he managed to convince his advisor that Mineralogy (with a full lab) and Optical Crystallography were excellent substitutes for Accounting. He was awarded a Bachelor of Science in Engineering (Chemical Engineering) from the University of Michigan in 1961.

Terry and Marie were married in 1961, and together they have three children (Andrew, Kenneth and Jennifer) and eight grandchildren. Although their children accompanied them on numerous mineral collecting field trips in the early years, none of them developed an interest in minerals. However, Andrew is keenly interested in mining memorabilia (flame lamps and mining sculptures).

Upon graduation from college Terry took a managerial position with Procter and Gamble in Cincinnati, Ohio, and Marie was hired as a secondary school teacher by the Cincinnati Board of Education. One week after arriving, they attended a meeting of the Cincinnati Mineral Society…which they promptly joined after Marie won the evening's door prize (an Estwing geologist's pick). From that time they had a new "family" in Cincinnati who shared a common interest in minerals, field collecting, and other social activities.

In 1973 Terry took a new managerial position in project engineering with Emery Industries, a company similar to Procter & Gamble in manufacturing of various chemical products. After 28 years there he retired in 2001.

Because the 1960s and 1970s were times of prosperity and nearly unfettered access to operating mines and quarries, it was only natural that the bulk of his early collection reflected personally collected specimens from the Midwestern states of Ohio, Indiana, Kentucky, Illinois, and Michigan. Terry and two other members of the Cincinnati Mineral Society (Bill Basbagill and Bob Martin) discovered millerite at Halls Gap, Kentucky, and collected celestine geodes from Mitchell, Indiana. Trades were made with other collectors and with Paul Desautels of the Smithsonian Institution, reducing the volume of Terry's collection while upgrading the quality and diversity. By the 1980s, purchases had replaced field collecting as access to localities dwindled.

In the early 1980s, following the advice of Carl Francis (curator of the Harvard Mineralogical Museum), Terry decided to specialize in one mineral species: calcite. Of particular help in building his new collection were dealers Neil and Chris Pfaff, Ken Roberts (with whom Terry shared a passion for aesthetic pseudomorphs), and Brad van Scriver, who provided exceptional Russian calcites and other important specimens. Terry also obtained calcite specimens from the Joe Kielbaso collection in 1994 and the entire India calcite collection of Berthold Ottens in 2003. Careful attention was given to acquiring specimens without damage, particularly those representing the wide variety of crystal habits, including the four twin laws of calcite. Colorful calcites and varieties of calcite were emphasized. Specimens from classic localities, both historical and modern, further enhance the collection. And special care was taken to preserve the labels of previous owners with each specimen.

Today his collection of mostly miniature to cabinet size specimens includes about 650 calcites from localities worldwide (over 100 are twins and 50 are of the pink manganese-rich or cobalt-rich variety), about 400 specimens from the Midwestern states (including some species other than calcite, especially from the iron and copper ranges), about 150 pseudomorphs (half of which are replacements after calcite), a miscellaneous assortment of about 300 other specimens, and a side-collection of mining memorabilia. In 1968 he won the American Federation of Mineralogical Societies National Trophy for best General Mineral Exhibit; and in 1971 his thumbnails won a trophy at the Midwest Federation of Mineralogical Societies show, though most of his thumbnails have since been sold off to other collectors. Since then he has often displayed specimens from his collection at the Tucson, Denver, Cincinnati, Rochester, Detroit and Munich shows, but he no longer exhibits competitively—except in 1996 at the Tucson Show, when he entered individual calcite specimens that won the Best Miniature and Best Small Cabinet awards.

Photographs of specimens from the Huizing collection have appeared in the Munich Show catalog; several earth science periodicals: Der Aufschluss, Lapis, extraLapis English, Mineralogical Almanac, Mineralogical Record, Rivista Mineralogica Italiana, Rock & Gem, and Rocks & Minerals; and in several books including American Mineral Treasures (2008), China, Mineralien-Fundstellen- Lagerstätten (2008), Indien, Mineralien-Fundstellen-Lagerstätten (2011), and Marokko, Land der schönen Mineralien und Fossilien (2003). Many of the photos were taken by Terry himself, and others by Jeff Scovil and Bert Ottens.

Terry (always with Marie at his side) has been an active participant in numerous mineralogical organizations over the years, including the Cincinnati Mineral Society (president, show chairman, program chairman, and Educational Foundation Award winner in 1984), the Midwest Federation of Mineralogical and Geological Societies (uniform rules committee, president in 1974-1975, American Federation Scholarship Foundation Award winner in 1991 for "distinguished achievement in the field of earth sciences"), Cincinnati Museum Center (where he is the Adjunct Curator of Mineralogy and manager of a large staff of volunteers—his work has greatly increased the collection and exhibits over the course of 35 years and 18,000 volunteer hours of work), the Geological Society of America (Terry and Marie chaired the Social Activities Committee for the 1981 Annual Meeting in Cincinnati), and Rocks & Minerals magazine as reviewing editor since 1975 when the relatives of founder Peter Zodac sold the magazine to the Helen Dwight Reed Educational Foundation. Currently he is also the North American representative for the Mineralogical Almanac (Russia), the Australian Journal of Mineralogy (Australia), and the UK Journal of Mines & Minerals (England), and a previous representative for the Mineralogical Record and Lithographie.

Terry's published articles in mineralogy include:
"Indiana Minerals: A Locality Index" (with R. E. Russell) (1986, Rocks & Minerals).
Five articles authored or co-authored in ExtraLapis English (2003): "Calcite – the mineral with the most forms," "Calcite and its relatives," "Dalnegorsk, Russia: clearly great calcite," "A bountiful harvest of calcite from the American Heartland," and "Michigan calcite and copper."
"Namibian diamond adventure" (with A. R. Kampf) (2007, Rocks & Minerals).
"Celestine from the Findlay Arch District, Ohio and Michigan" (with J. C. Medici) (2008, in American Mineral Treasures).

Terry and Marie have become world travelers over the years, going to see mineral exhibits, museums, personal collections, mines, mineral markets, places of geological interest and various mineral shows, symposia and conferences in Australia, Brazil, Russia, Norway, Germany, China, Namibia, Poland, the Czech Republic, Morocco, France, Austria, England, Italy, Spain and Switzerland. But they also enjoy staying at home and tending to their extraordinary gardens of over 300 trees, shrubs, hostas, ferns and other perennials (featured in the September/October 2012 issue of Horticulture magazine). ____________________________________
