Although I never had the opportunity to meet Art Bergeron in person, he was the only professional Civil War historian that I corresponded with on a regular basis, and I was greatly saddened to hear of his passing. When it came to his beloved Louisiana, he cheerfully helped me on so many occasions that it is impossible to count. And it wasn't just token help off the top of his head, he freely gave of his own time to do research for me. On a personal level, I will sorely miss his advice and generosity, and every serious student (amateur and professional) of Civil War Louisiana knows what a loss his untimely death truly is. My thoughts go out to his family and friends. Rest in Peace, Art.
