Jane Stephens was an Irish zoologist who was considered a leading authority on sponges in Ireland with specialised knowledge in other marine life who identified and named over 40 sponges new to science. From 1905 to 1920 she was employed in the Natural History Division of the National Museum of Ireland working primarily on the collections of marine invertebrates, including taking part in the Clare Island Survey. Robert Lloyd Praeger testified to her knowledge of and work with Irish sponges stating that "Most of what we know of this group, whether marine or fresh-water, in Ireland, or off the Irish coasts, is due to her work."
