Susan Marguerite Robinson earned a bachelor's degree in Geology and Education from the State University of New York in 1971 and later studied art and art history at Queen's University in Kingston, Ontario. While living in Canada she was a member of the Manotick Art Association and the Ottawa Art Association, in which she won several competitions. She has painted and sold many wildlife scenes (especially birds), her principal subject matter, but is also an accomplished mineral and gem artist, having accepted 35 commissions thus far. She paints in a rigorously realistic style, in acrylic paint on canvas and on art board, and also produces drawings in pen and ink. Several of her mineral paintings have been displayed at the Tucson Gem and Mineral Show, and at the Rochester Mineralogical Symposium, and she was the featured guest artist at the 1996 Munich Mineral Show. One painting (a Guerrero amethyst) was published in Panczner's Minerals of Mexico (1986), and her pen and ink drawings have appeared in Rocks & Minerals, on the covers of the Rochester Mineralogical Symposium program books, and in Canadian Gemmologist. She wrote and illustrated a self-published book entitled Is This an Agate? An Illustrated Guide to Lake Superior's Beach Stones, as well as a collector's guide to Copper Country minerals. Since 1987 she has also written an extensive series of articles for Rocks & Minerals on mineral and mining artists.Susan lives in Hancock, Michigan with her husband, mineralogist George Robinson, curator of the Seaman Mineralogical Museum at Michigan Tech.
