Arthur Wilson Stelfox

[2] He was educated at Campbell College, Belfast and went on to study architecture in Ireland and England, being elected as an associate of the Royal Institute of British Architects on the 2 November 1908.

[4] In October 1925, the couple jointly found the first confirmed record of the rare slime mold Diderma lucidum in Ireland, at Powerscourt Waterfall.

[8] Stelfox recognised the enormous value of the Alexander Henry Haliday Hymenoptera collection held at the National Museum of Ireland and undertook the task of curating and caring for it.

In doing so he added significantly to the scientific knowledge of many species by ensuring the correct identification and labelling of specimens and the cross referencing of Haliday's notes.

[4] Despite this specialization Stelfox proved his standing as a naturalist by publishing papers on a total nine Orders of insects and was regarded as an authority on molluscs, Irish plants and other aspects of natural history.

[4] During this time Stelfox also continued to make significant contributions to the scientific knowledge on Irish flora and fauna by describing many new species.

In 1948 Stelfox retired from his position at the National Museum of Ireland but continued to undertake numerous field trips and collect plants, molluscs and insects.
