Mary Virginia Orna, Professor of Chemistry at The College of New Rochelle, received a B.S. in Chemistry from Chestnut Hill College, and M.S. and Ph.D. degrees in Analytical Chemistry from Fordham University. Her research interests include pigment and dye analysis of archaelogical artifacts and, in particular, of medieval manuscripts. She is the author or editor of 14 books(including ACS Symposium Series volumes) and over a hundred encyclopedia, journal, and monograph articles. She is the recipient of numerous awards including a Fulbright Fellowship for Israel, the ACS George C. Pimentel Award in Chemical Education (1999) and the ACS Volunteer Service Award (2009). In 1990, in collaboration with John T. Stock of the University of Connecticut, she began conducting study tours for students as partial fulfillment of the requirements of a course in the history of science. These study tours expanded over the years to include adult learners; they also broadened their scope to include most of the venues described in this volume.
