Sir George Watt (24 April 1851 – 2 April 1930) was a Scottish physician and botanist who worked in India as "Reporter" on economic botany and during the course of his career in India he compiled a major multivolume work, The Dictionary of Economic Products of India, the last volume of which was published in 1893. An abridged edition of his work was also published as the single volume Commercial Products of India in 1908. He is honoured in the binomials of several plants named after him. Life and career Watt was born in Old Meldrum, Aberdeenshire, Scotland, the third son of John Watt. He was educated at Grammar School, King's College and Marischal College, Aberdeen, and later attended both the University of Aberdeen and the University of Glasgow. He received the degrees of M.B. and C.M. in 1873. He enjoyed teaching and joined the University of Glasgow as a prodissector to the Professor of Anatomy. Around 1864, there was a famine in Orissa and the then Lieutenant-Governor of Bengal, Sir George Campbell was firm that agricultural education was key to avoiding similar disasters and following the recommendations of Sir John Strachey's Famine Commission, a need to carry out scientific study to improve the food supply in India was noted. In order to fulfil this requirement, and on the recommendation of J.D. Hooker, he was selected for the post Professor of Botany, at Presidency College, Calcutta University and joined there in 1873–74. He taught for ten years at a college in Hoogly and at the same time began to study the local botany and began to form a private herbarium. He followed a system of numbering specimens in the field with numbered tag labels detached from similarly numbered sheets in the field to avoid mistakes in labelling. In 1879 he travelled around northwest Punjab and he described several new plant species from the Chamba region. In 1881 he was posted as surgeon to the Burma-Manipur Delimitation Commission with special permission to conduct botanical studies during the expedition. On his return he was made in charge of the Calcutta International Exhibition for 1883–84. Watt organized a 1700-page catalogue for the economic section of the exhibition that was in charge of. Towards the end of the exhibition, the government suggested that the catalogue should be expanded. The expanded version was ready for the Colonial and Indian Exhibition of London in 1886. This
