Morris William Travers (24 January 1872 – 25 August 1961), the founding director of the Indian Institute of Science, was an English chemist who worked along with Sir William Ramsay in the discovery of xenon, neon and krypton. His work on several of the rare gases earned him the name Rare gas Travers in scientific circles.
Travers was born in Kensington, London, the son of William Travers MD, FRCS (1838-1906), an early pioneer of aseptic surgical techniques. His mother was Anne Pocock. Travers went to school at Ramsgate, Woking and Blundell's School.
He then went to University College, where he began to work with Sir William Ramsay. Travers helped Ramsay to determine the properties of the newly discovered gases argon and helium. They also heated minerals and meteorites in the search for further gases, but found none. Then in 1898 they obtained a large quantity of liquid air and subjected it to fractional distillation. Spectral analysis of the least volatile fraction revealed the presence of krypton. They examined the argon fraction for a constituent of lower boiling point, and discovered neon. Finally xenon, occurring as an even less volatile companion to krypton, was identified spectroscopically. He knew the entire research story and wrote the biography of Sir William Ramsay in 1956 "A life of Sir William Ramsay, K.C.B., F.R.S."
