John T. Graves

John Thomas Graves (4 December 1806 – 29 March 1870) was an Irish jurist and mathematician. He was a friend of William Rowan Hamilton, and is credited both with inspiring Hamilton to discover the quaternions in October 1843 and then discovering their generalization the octonions himself (he called them octaves) later that same year.[1] He was the brother of both the mathematician and bishop Charles Graves[2] and the writer and clergyman Robert Perceval Graves.
