Dr Francis Buchanan, later known as Francis Hamilton or Francis Buchanan-Hamilton, was a Scottish physician who made significant contributions as a geographer, zoologist, and botanist while living in India. He was born at Bardowie, Scotland, and studied medicine at the University of Edinburgh, graduating in 1783. He also studied botany. He first served on merchant ships to Asia and then joined the Bengal Medical Service in 1794. Buchanan's training was ideal as a surgeon naturalist for a political mission to the Kingdom of Ava in Burma under Captain Symes. The Ava mission set sail on the Sea Horse and passed the Andaman Islands, Pegu, and Ava before returning to Calcutta. Subsequently Buchanan-Hamilton was asked to survey South India. He conducted a survey of Mysore in 1800 and a survey of Bengal from 1807-1814.
For the survey of Bengal he was asked to report on topography, history, antiquities, the condition of the inhabitants, religion, natural productions (particularly fisheries, forests, mines, and quarries), agriculture (covering vegetables, implements, manure, floods, domestic animals, fences, farms, and landed property, fine and common arts, and commerce (exports and imports, weights and measures, and conveyance of goods). His conclusions were made into a series of reports, of which these papers are the manuscripts. He also collected and described many new plants in the region, and collected a series of watercolours of Indian and Nepalese plants and animals, probably painted by Indian artists, which are now in the library of the Linnean Society of London.
He succeeded William Roxburgh to become the superintendent of the Calcutta botanical garden in 1814, but had to return to Britain in 1815 due to his ill health and in the same year he inherited his mother's estate and in consequence took her surname of Hamilton, referring to himself as "Francis Hamilton, formerly Buchanan" or simply "Francis Hamilton". However, he is variously referred to by others as "Buchanan-Hamilton", "Francis Hamilton Buchanan", or "Francis Buchanan Hamilton". From 1815 until 1829 he was Regius Keeper of the Royal Botanic Garden in Edinburgh replacing Dr William Roxburgh.
Lt. Colonel Fleming Mackenzie was born in Tapah, Malay Straits' Settlements (Malaysia) in 1897. His father was the Chief Surveyor for the opening up of the area. He returned to England with his mother, attending first St Paul's and later Bedford schools.
At the outbreak of WWI, Mackenzie became a tank commander and was present throughout the Battle of Cambrai. Joining the Indian Army (1st Battalion, XV Punjab Regiment) after the War, he served in Calcutta, recruiting in Palampur, and moved with his battalion up to the North West Frontier (bordering Waziristan and Afghanistan) in 1936. He was part of the Escort to the Trade Agent to Tibet in 1938-39.
During the 1939-45 War, Mackenzie raised a battalion of the XV Punjab Regiment and later commanded a battalion of the Mahratta Light Infantry fighting in the Greek Islands. He retired from the Indian Army after Partition in August 1947.
Returning to the UK, Mackenzie later qualified as a Guide Lecturer and escorted many foreign visitors, including some who came for the Queen's Coronation in 1953. He died in 1980.
Alexander Hamilton (1762-1824) was one of the first Europeans to study Sanskrit. Hamilton joined the East India Company and arrived in India in 1783. He joined the Asiatic Society of Bengal founded by William Jones. Hamilton returned to Europe around 1797 and went to France after the Treaty of Amiens (1802) to collate Sanskrit manuscripts held at the Bibliothèque Nationale in Paris. When war broke out between Britain and France in 1803 Hamilton was interned as an enemy alien, but was released to carry on his researches at the insistence of the French scholar Constantine Volney. Hamilton taught Sanskrit to Volney and others, including Friedrich Schlegel and Jean-Louis Burnouf, the father of Eugene Burnouf. Hamilton spent most of his time compiling a catalogue of Indian manuscripts in the library which was published in 1807. Hamilton was elected a Fellow of the Royal Society in 1808 and became professor of Sanscrit and Hindoo literature at Haileybury College. He died at Liscard on 30 December 1824.
Graves Chamney Haughton (1788-1849) was educated in England before travelling to India in 1808 with the East India Company. He became proficient in Hindustani, studying at Fort William College. He returned to England in 1815 and in 1817 was appointed assistant professor at Haileybury College and held the post of professor of Sanskrit and Bengali from 1819 to 1827. He was supported by various prominent academics when he attempted in 1832 to be elected as the first Boden Professor of Sanskrit at Oxford University but he stood down in favour of Horace Hayman Wilson. He was a founding member of the Royal Asiatic Society and served as its Librarian from 1831-1837. He died of cholera in Paris on 28 August 1849.
