Louis J. Cabri
Louis Jean-Pierre Cabri (born February 23, 1934 in Cairo) is an eminent Canadian scientist in the field of platinum group elements (PGE) mineralogy with expertise in precious metal mineralogy and base metals at the Canada Centre for Mineral and Energy Technology (CANMET). First as Research Scientist and later as Principal Scientist (1996–1999). In the 1970s he discovered two new Cu–Fe sulfide minerals, "mooihoekite" and "haycockite". In 1983 Russian mineralogists named a new mineral after him: cabriite (PdSnCu). Family. Louis was born in Cairo as son of Ludovicus Petrus Maria Cabri (born in Antwerp, Belgium) and  Cézarinne-Marie Kahil (born in Alexandria, Egypt). His family is of Dutch Huguenot descent (from 's-Hertogenbosch, The Netherlands) with its origins in Saint-Jean-du-Gard, France. He is married to Canada's well-known ceramic artist Mimi Mignon De Meillon. His son Louis Andrew De Meillon Cabri is a Canadian writer and poet (New Creative Writing). His daughter Annemarie was a dancer with "Het Nationale Ballet" in Amsterdam, directed Cabri Creative Dance school in Victoria, British Columbia and is now a dance educator and performer in Toronto, Ontario, Canada. Annemarie teaches for "YOUdance" the outreach program of The  National Ballet Company (Canada); in Victoria (BC) she directs and teaches summer programs for this ballet company ". Claudia, their youngest child is a modern art painter living and working in her restaurant in Paris. Scientific Achievements. According to "The Royal Society of Canada", Louis J. Cabri ""...attained international eminence for his work on sulphides and tellurides, on the platinum-groupminerals, and ... for pioneering mineralogical applications of micro-beam trace-element analytical techniques such as micro-Proton-induced X-ray emission (PIXE) and Secondary-Ion Mass Spectrometry (SIMS). His fundamental work on the platinum-group minerals has brought order and understanding  to a previously chaotic field of knowledge. All his work is characterized by innovative experimental approaches that have greatly advanced our knowledge and understanding of the behaviour of precious metals in Earth systems and mineral process products. ..." ". He started his scientific career with many field explorations in Africa (Ghana, Sierra Leone, Zimbabwe and South Africa). Later, he pursued phase-stability and crystal-chemistry relationships in the [Cu–Fe–S] (Copper-Iron-Sulfide) System, which led to his discovery in 1972 of two new Cu–Fe sulfide minerals, "Mooihoekite" ( Cu9Fe9S16) and "Haycockite" (Cu4Fe5S8). He went on researching platinum group minerals, and  characterised this group and their crystal chemistry, nomenclature, geochemistry and geological occurrence. He has studied many of the world's PGM deposits, both primary and placer, for example Sudbury (Ontario), Tulameen River (British Columbia), Stillwater Complex (Montana), Itabira (Brazil), Norilsk–Talnakh (Russia), Kondyor Massif (Russia), Great Dyke (Zimbabwe), Freetown Complex (Sierra Leone), and Onverwacht, the Witwatersrand Reef and the Merensky Reef of the Bushveld Complex (South Africa). In 1983, Russian mineralogists named a new mineral after him : Cabriite (Pd2SnCu). He was chairman and president for a number of national and international geological and mineralogical associations and has chaired and co -chaired numerous technical meetings, nationally and internationally. He serves as a consultant to industry, government organizations and universities in Canada and abroad, independently since 1999, incorporated in 2004 and a principal of CNT-Mineral Consulting Inc. since 2005.
