Sir Eric William Riches, MC, FRCS (1897 – 1987) was a British surgeon, urologist, and decorated British Army officer. In 1955, he developed a new cystoscope, which was named after him as the Riches Cystoscope, in order to standardise the equipment and its attachments. He gave the Hunterian Oration in 1938 and 1942, and the Bradshaw Lecture in 1962.
