Educated at Belvedere College, and subsequently at University College Dublin, he graduated from University College Dublin both as a medical doctor and with a Masters in Science. He subsequently earned a PhD in Zoology. O’Rourke’s 1948’s survey of Irish ants built on the earlier work of Stelfox and provided an authoritative description of Irish ants.[1] O’Rourke (1956) provided an early consideration of the importance of ants as disease vectors. He was appointed Professor of Zoology at University College Cork and was elected a Member of the Royal Irish Academy and Fellow of the Royal Entomological Society of London.
