My good friend Sandra Petrovich died last week, and her family, friends and students are still reeling from the shock. Sandra was an ardent pet lover, a brilliant historian, and a gifted writer. She knew so much about seventeenth century history that I always thought she must have brought some cellular memory with her when she came into this life. She laughed at the idea, but everybody who knew her realized she was an old soul with a wisdom far beyond her years. Perhaps that’s why she left us at such a young age. She will be greatly missed.
