Photogravure from a photograph by Maull & Polyblank. Between 1818 and 1843 Everest (1790-1866) conducted the survey of India. He was appointed Superintendent of the Great Trigonometrical Survey of India in 1823 and Surveyor-General of India in 1830. One of the greatest achievements of the survey was the measurement of the meridional arc of 11.5 degrees from the Himalayas to Cape Comorin. In 1852 the height of Peak XV in the Himalayas was measured at 29,002 feet above sea level by the survey team. In 1865 in honour of his work as a surveyor, Peak XV was renamed Mount Everest.
