Edward Bruce Williamson
Edward Bruce Williamson (July 10, 1877 – February 28, 1933) was an American banker and amateur naturalist who took a special interest in the odonata. He has been considered one of the giants of North American dragonfly studies. He also took an interest in gardening and was involved in creating several hybrid irises. The rare dragonfly genus Williamsonia was named after him and it currently includes two species including Williamsonia fletcheri which was described by him in 1923.
