Andrew Wilson Baird|1842|1908| Andrew Wilson Baird (born 1842 died 1908), colonel, royal engineers, eldest son in a family of five sons and four daughters of Thomas Baird, of Woodlands, Cults, Aberdeen, and of Catherine Imray, his wife, was born at Aberdeen on 26 April 1842. Educated at the grammar school and at Marischal College, Aberdeen, Andrew entered the Military College of the East India Company at Addiscombe in June 1860, and was transferred to the Royal Military Academy at Woolwich in January 1861, owing to the amalgamation of the Indian with the royal army. He received a commission as lieutenant in the royal engineers on 18 December 1861, and after instruction at Chatham sailed for India on 1 March 1864. Baird was employed as special assistant engineer of the Bombay harbour defence works, and had charge of the construction of the batteries at Oyster Rock and Middle Ground until the end of 1865. He was then appointed special assistant engineer in the government reclamations of the harbour foreshore. During 1868 he served as assistant field engineer in the Abyssinian expedition under Sir Robert Napier, afterwards Lord Napier of Magdala. For his work as traffic manager of the railway from the base he was mentioned in despatches (''London Gaz'.' 30 June 1868), and received the war medal.

In December 1869 Baird became assistant superintendent of the great trigonometrical survey of India. He was employed successively on the triangulation in Kathiawar and Gujarat. His health suffered from the extreme heat in this arid country, and he went on furlough to England in the spring of 1870. While he was at home, Colonel (afterwards General) James Thomas Walker, the surveyor-general of India, chose him to study the practical details of tidal observations and their reduction by harmonic analysis as carried on under the supervision of Sir William Thomson, afterwards Lord Kelvin [q. v. Suppl. II], for the British Association.

Tidal observations were only undertaken by the survey of India, in the first instance, with the object of determining the mean sea level as a datum for the trigonometrical survey. But Baird, widening his aim, determined ' to investigate the relations between the levels of land and sea on the coasts of the gulf of Cutch, which were believed by geologists to be gradually changing. This necessitated a more exact determination of the mean sea level than had hitherto sufficed for the operations of the survey' (Baird, Manual of Tidal Observations, and their Reduction by the Method of Harmonic Analysis, 1886, pref.). It was decided to carry out observations at stations in the gulf of Cutch, in accordance with the recommendations of the tidal committee of the British Association, by self-registering gauges, set up for at least a year at a time. Having returned to India in December 1872, Baird selected three stations on the gulf of Cutch for his tidal observatories, one at the mouth, another at the head and as far into the 'Runn' as possible, and the third about the middle of the gulf. These observatories were inspected periodically by Baird and his assistant in turn, in circumstances involving severe privation. Baird was promoted captain on 4 April 1874. In 1876 the governor-general in council commended Baird's labours, and in July 1877 instructions were issued for systematic tidal observations at all the principal Indian ports, and at other ports on the coast lines where the results would be of general scientific interest, apart from their usefulness for purpose of navigation. To Baird, who had become deputy superintendent in the great trigonometrical survey department, was entrusted the general superintendence.

Meanwhile, in 1876, Baird was at home, working out with assistance the results of his observations in the gulf of Cutch. In the autumn he read a paper on 'Tidal Operations in the Gulf of Cutch' before the British Association at Glasgow. On his return to India in June 1877 he organised a new department of the survey along the coast lines from Aden to Rangoon, with its centre at Poona, Bombay.

In July 1881 Baird was at Venice as one of the commissioners from India to the third international congress of geography, and there he exhibited a complete set of tidal and levelling apparatus in practical use in an adjoining canal. Baird was awarded the gold medal of the first class.

After some eighteen months on furlough in England, Baird, who had been promoted major on 18 December 1881, resumed his tidal duties in India in March 1883, his field of operations including India, Burma, Ceylon, and the Andaman Islands. On 27 August the great volcanic eruption of Krakatoa, in Java, caused a wave which was distinctly traceable in all the tidal diagrams, and Baird sent a paper on the subject to the Royal Society, of which he was elected a fellow in the following May (Proc. Roy. Society No. 229, 1884).

Between July 1885 and August 1889 Baird was temporarily employed as master of the mint at both Calcutta and Bombay, and also as both assistant and deputy surveyor-general of India. He was promoted brevet lieutenant-colonel on 18 December 1888, and on 12 August 1889 became permanent mint master at Calcutta. In that office he re-organised the manufacturing department. In 1895-6, in accordance with his proposals, the government withdrew from circulation worn and dirt-encrusted coinage.

Promoted regimental lieutenant-colonel on 9 April 1891, brevet colonel on 29 September 1893, and substantive colonel on 9 April 1896, he retired from the mint owing to the age-limit on 20 April 1897, and received the special thanks of the governor-general for his varied services. He was created C.S.I, in June 1897. On his return home, he bought a small property at Palmers Cross, near Elgin. He died suddenly of heart failure in London, on 2 April 1908, and was buried at Highgate.

Sir George Darwin, who first made Baird's personal acquaintance at Lord Kelvin's house in 1882, wrote of Baird's tidal work on his death, 'In science he has left a permanent mark as the successful organiser of the first extensive operations in tidal observations by new methods. The treatment of tidal observations is now made by harmonic analysis in every part of the world, and this extensive international development is largely due to the ability with which he carried out the pioneer work in India'. Baird married at Aberdeen, on 14 March 1872, Margaret Elizabeth, only daughter of Charles Davidson, of Forrester Hill, Aberdeen, and of Jane Ross. She survived him with a family of two sons and five daughters.

Besides the works cited, Baird was author of articles on the Gulf of Cutch, Little Runn, and Gulf of Cam bay in the 'Bombay Gazetteer' ; 'Notes on the Harmonic Analysis of Tidal Observations', published by order of the secretary of state (1872) ; 'Auxiliary Tables to facilitate the Calculations of Harmonic Analysis of Tidal Observations' (1897); 'Account of the Spirit-Levelling Operations of the Great Trigonometrical Survey of India' (British Association, 1885). He was also joint author with Sir George Darwin of a report on the results of the 'Harmonic Analysis of Tidal Observations' (Proc. Roy. Society March 1885) ; and with Mr. Roberts of the Nautical Almanac Office of 'Annual Tidal Tables of Indian Ports'.
