Beare was born in Adelaide, South Australia, a son of Thomas Hudson Beare of Netley, Hampshire, who arrived in South Australia aboard Duke of York in July 1836 and his second wife Lucy Beare, née Bull, who arrived aboard Canton in May 1838. He was educated at Prince Alfred College and the University of Adelaide, where he was awarded the first South Australian Scholarship, before going to University College London to complete his studies. In 1884, he joined the staff of University College, London, and worked for Professor Alexander Kennedy in various teaching and engineering roles. In 1885 he married Louise Newman. In 1887 he was appointed to the new chair of mechanics and engineering at Heriot-Watt University, and in two years built up a successful department. He returned to London in 1889, to replace his mentor Prof Kennedy as the chair of engineering at University College and to oversee the building of the new Engineering Department in 1895. In 1901 Hudson Beare was appointed as the third Regius Professor of Engineering in Edinburgh University. He moved to an impressive townhouse at 10 Regent Terrace on Calton Hill. In his time in Edinburgh he increased the number of engineering students and ensured the department had new and well-equipped facilities. With the influx of new students from around the world to the re-invigorated department, in 1931 he organised its transfer from its site in central Edinburgh to the Sanderson Engineering Laboratories, part of the King's Buildings in the south of the city. A building in this campus is named in his honour. He served at Edinburgh University until 1940, including as Dean of the Faculty of Engineering for 22 years. In 1908 he was appointed convenor of the university's Military Education Committee, in which capacity he raised the profile and capabilities of the university's Officer Training Corps. During the First World War he was a captain in the Forth Volunteer Division of the Royal Engineers. He served from 1921 to 1926 as the second Chairman of the Central Organisation of Military Education Committees of the Universities and University Colleges, what is now the Council of Military Education Committees of the Universities of the United Kingdom. He was Vice-President of the Royal Society of Edinburgh for two periods: 1909 to 1915, and 1923 to 1926, and was president of the Royal Scottish Society of Arts from 1906 to 1908. In 1921 he was appointed by the Secretary of State for Scotland as an assessor on the Central Miners' Welfare Committee, which he served on until his death. He was made Deputy Lieutenant of the County of the City of Edinburgh in 1920, and was knighted in 1926. He received an honorary LLD degree from the University of Edinburgh in 1936. Sir Thomas Hudson Beare was a member of the Institution of Civil Engineers, a member and later an honorary life member of the Institution of Mechanical Engineers, and a member and vice-president of the Institution of Structural Engineers. Any spare time he had, he devoted to the study of Coleoptera, on which subject he was accepted as an authority by entomologists.
Works
Hudson Beare's talents seem mainly to have been towards academic administration and inspiring younger engineers, but he did publish research that was appreciated at the time: The Building-Stones of Great Britain: their Crushing Strength and other Properties reported the results of his extensive experimental testing in his laboratories at University College London, of different types of rock from around the British Isles, and this was awarded a Telford premium by the Institution of Civil Engineers. He also translated from the Italian, for the benefit of engineering students, Luigi Cremona's Graphical Statics: Two Treatises on the Graphical Calculus and Reciprocal Figures in Graphical Statics. Hudson Beare wrote a number of articles for the Dictionary of National Biography and for the 1911 edition of Encyclopædia Britannica. These are identified in these publications by the initials 'T. H. B.' His contributions to the Dictionary of National Biography include entries on: John Smeaton, George Stephenson, Henry Palfrey Stephenson, Robert Stephenson and William Symington. To the Dictionary of National Biography, 1901 supplement he contributed entries on Joseph Bazalgette, Charles Bright, James Brunlees, John Coode, James Douglass, John Fowler, James Gordon, John Grover, John Hawkshaw, Thomas Hawksley, William Haywood, John Hopkinson, William Lindley and Robert Rawlinson. He wrote the article on Water Motors in the Encyclopædia Britannica Eleventh Edition.
