Excerpt: The insect brooch was a popular genre of Victorian jewelry, and the late Dr. Moser Lyon Stadiem of New Orleans owned one of the finest private collections of Victorian jewelry in the United States. Dr. Stadiem's rarities, valued at over a million dollars, were obtained by the Famous-Barr Company of St. Louis five years after his death in 1964. 294 lots of the collection were sold at auction by Parke-Bernet Galleries, New York City, on 6 October 1969, and among these were some of the finest known examples of the great age of entomological jewelry.
