John William Stubbs (1 Feb 1821–10 Oct 1897) was an Irish mathematician and clergyman who served as bursar of Trinity College Dublin (TCD).
[1] He has been co-credited with introducing the geometric concept of inversion in a circle, and late in life he authored a book on the history of the University of Dublin.
[3] He published in mathematics over the next few years, and has been co-credited (along with John Kells Ingram) with introducing the geometric concept of inversion in a circle,[4] in a joint paper.
[6] This Ingram & Stubbs innovation was highlighted in John Casey's work, A Sequel to the First Six Books of Euclid containing An Easy Introduction to Modern Geometry, with Numerous Examples (4th edition, 1886),[7] and also in the Proceedings of the Royal Irish Academy in 1845.
In 1845 Stubbs got his MA, was made a Fellow of TCD, and was admitted to holy orders, henceforth shifting his focus to church matters.
