Sydney Luxton Loney, M.A. (16 March 1860 – 16 May 1939) was a Professor of Mathematics at the Royal Holloway College, Egham, Surrey, and a fellow of Sidney Sussex College, Cambridge, England.[1] He authored a number of mathematics texts, some of which have been reprinted numerous times. He is known as an early influence on Srinivasa Ramanujan.[2]
