Sir William Rowan Hamilton

Sir William Rowan Hamilton (1805-1865) was an eminent Irish mathematician, born in Dublin. Such was his precocity that at 13 he was versed in thirteen languages, and by 17 was an acknowledged master in mathematical science. While yet an undergraduate at Trinity College, Dublin, he was appointed in 1827 professor of Astronomy in Dublin University, and Astronomer-Royal of Ireland. His mathematical works and treatises, of the most original and a far-reaching character, brought him a European reputation, and embraced his "Theory of Systems of Rays," "A General Method in Dynamics," and the invention of "Quaternions". He was knighted in 1835.
