Marcelle Weber

Marcelle Juanita Horn Weber, amateur mineralogist, well-known micromounter and long-time resident of Guilford, Connecticut, was born in Randolph County, Indiana, on September 19, 1918, the daughter of Vera Ethel Pratt and George Betrand Horn, and electrical engineer. By 1920, Marcelle and her family had resettled to Fort Wayne, Allen County, Indiana.

Marcelle earned an A.B. in Business Administration from Indiana University in 1940. After graduating she moved to Fairfield, Connecticut to work at Remington Arms, and married Charles H. Weber, Jr. there in 1942. She subsequently served as private secretary in her husband's business as a manufacturer's representative. Over many years, she was actively involved in national, State and local chapters of some dozen lineage societies such as the Daughters of the American Revolution, Women Descendants of the Ancient and Honorable Artillery Company, etc.

A nearly lifelong passion for mineralogy led to Marcelle's recognition as one of the most knowledgeable and respected amateur mineralogists in the U.S. and Canada. She had a remarkable ability to sight identify minerals, especially from her favorite locality, the Poudrette quarry, Mont Saint-Hilaire, Quebec. Her memory was phenomenal, allowing her to give year and month for any important find or trip to Hilaire. Marcelle and Charlie first visited the Poudrette quarry in 1968, ultimately returning some 240 times, and traveling a total of approximately 180,000 miles to do so. Their diligence at collecting there, and Marcelle's reluctance to throw any specimen away, are attested to by the mountains of specimen-filled beer flats crowding everything eise from their cellar, and leaving only a six inch gap between the tops of the Stacks and the ceiling! As a result of her work, she was named to the Micromounters Hall of Fame. And in the early 1990s Marcelle and Charlie discovered and supplied the type material for a new Mont Saint-Hilaire mineral species that was subsequently named charmarite-2H in their honor. Specimens of charmarite-2H and others from Marcelle and Charlie's extensive collection are held by the Smithsonian Institu¬tion, the Canadian Museum of Nature, and other institutions.

Marcelle was an avid mineral photomicrographer, lecturer and author, taking her message to micromount symposia and Confer¬ences throughout North America. She and Charlie also represented the Mineralogical Record at Eastern mineral shows, particularly the Springfield Show, and often helped out at the subscription table at the Tucson Show. Over the years, she inspired many people to become interested in mineral collecting, especially the study of micromounts, to subscribe to the Mineralogical Record, and to join the fraternity of advanced collectors at Mont St-Hilaire. She was an active member of the Friends of Mineralogy (Secretary), the Micromounters of New England, the Tucson Gern and Mineral Society, the Mineralogical Association of Canada, the Baltimore Mineral Society, the New Häven Mineral Club (President), and the Stamford Mineral Club (President).

Marcelle Weber died at home on Tuesday, July 8, 2003 after a brief illness. She is survived by her daughters, Ruth Weber Hoffman and Martha Jane Weber; and her son, Charles H. Weber, III.
