Major General Sir Andrew Scott Waugh (3 February 1810 – 21 February 1878) was a British army officer and Surveyor General of India who worked in the Great Trigonometrical Survey. He served under Sir George Everest and succeeded him in 1843. Waugh established a gridiron system of traverses for covering northern India. Waugh is credited with naming the peak of Mount Everest. Early life Waugh was the first son of General Gilbert Waugh who served as military auditor-general in Madras. After studying at Edinburgh he joined Addiscombe Military Seminary in 1827 and was commissioned with the Bengal Engineers on 13 December of the same year. He trained at Chatham where he studied under Sir Charles Pasley before reaching India in May 1829. He assisted Captain Hutchinson in establishing a foundry at Kashipur and became an adjutant of the Bengal sappers and miners on 13 April 1831. In 1832 he was posted to the Great Trigonometrical Survey under George Everest. Waugh surveyed many parts of central India before moving to the headquarters in Dehra Dun. Everest noted that Waugh and Renny were the best in mathematical skills and in the handling of instruments. Surveyor General In 1843, Everest retired and recommended that Waugh was the best replacement for the position of Surveyor General. Waugh surveyed the Himalayan region. The survey covered nearly 1690 miles from Sonakoda to Dehra Dun. The great height of this area, however, combined with its unpredictable weather, meant that few useful sightings were obtained before 1847. In an era before the electronic computer, it then took many months for a team of humans to calculate, analyze and extrapolate the trigonometry involved. According to accounts of the time, it was 1852 when the team's leader of the human computers, Radhanath Sikdar, came to Waugh to announce that what had been labeled as "Peak XV" was the highest point in the region and most likely in the world. Sikdar and Waugh checked their calculations again and again in order to make no mistake in them and then sent a message to Royal Geographical Society from their headquarters in Dehradun, where they found that Kangchenjunga is not the highest peak of the world. To ensure that there was no error, Waugh took his time and did not publish this result until 1856, when he also proposed that the peak be named Mount Everest in honor of his predecessor.
