Dr Edward John Routh, the eminent mathematician, died at Cambridge yesterday morning. The deceased gentleman was born at Quebec in 1831, and was a son of Sir Randolph Routh, K.C.B one time Commissary-General. He was educated in the University College, London, and Peterhouse, Cambridge, and from the first showed signs of brilliant scholarship. He was the gold medallist of his year, Senior Wrangler and Smith's Prizeman in 1854, and Adam's Prizeman at Cambridge, etc. He adopted the profession of teacher and trained twenty-seven Senior Wranglers and more than forty Smith's Prizemen. In 1888 be retired, when as a mark of esteem, his pupils presented him with his portrait, painted by Herkomer. Dr Routh was also well known as an author on scientific subjects. He contributed original articles to the Mathematical Society of London, the Quarterly Journal of Mathematics and the Royal Society. He is, however, perhaps best known for his "Treatise on Rigid Dynamics," which has gone through seven editions, and has been translated into German.
