James Thomson FRS FRSE LLD (16 February 1822 – 8 May 1892) was a British engineer and physicist, born in Belfast, and older brother of William Thomson (Lord Kelvin).
Born in Belfast, much of his youth was spent in Glasgow. His father James was professor of mathematics at the University of Glasgow from 1832 onward and his younger brother William was to become Baron Kelvin. James attended Glasgow University from a young age and graduated (1839) with high honours in his late teens. After graduation, he served brief apprenticeships with practical engineers in several domains; and then gave a considerable amount of his time to theoretical and mathematical engineering studies, often in collaboration with his brother, during his twenties in Glasgow. In his late twenties he entered into private practice as a professional engineer with special expertise in water transport. In his early thirties, in 1855, he was appointed professor of civil engineering at Queen's University Belfast. He remained there until 1873, when he accepted the Regius professorship of Civil Engineering and Mechanics at the University of Glasgow (in which post he was successor to the influential William Rankine) until he resigned with failing eyesight in 1889.
In 1875 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were his younger brother William Thomson, Peter Guthrie Tait, Alexander Crum Brown, and John Hutton Balfour. [1] He was elected a Fellow of the Royal Society of London in June 1877. [2]
He served as President of the Institution of Engineers and Shipbuilders in Scotland from 1884 to 1886.
In later life he lived at 2 Florentine Gardens, off Hillhead Street. [3]
He died of cholera in Glasgow on 8 May 1892. He is buried on the northern slopes of the Glasgow Necropolis overlooking Glasgow Cathedral. One obituary described Thomson as “a man of singular purity of mind and simplicity of character“, whose “gentle kindness and unfailing courtesy will be long remembered.” [4]
James Thomson is known for his work on the improvement of water wheels, water pumps and turbines. Also his innovations in the analysis of regelation, i.e., the effect of pressure on the freezing point of water, and his studies in glaciology including glacier motion, where he extended the work of James David Forbes. He studied the experimental work of his colleague Thomas Andrews, concerning the continuity of the liquid and gaseous states of matter, and strengthened understanding of it by applying his strong knowledge of thermodynamics. He derived a simplified form of the Clapeyron equation for the solid-liquid phase boundary. He proposed the term triple point to describe the conditions for which solid, liquid and vapour states are all in equilibrium. [5]
He also had contributions in the realm of fluid dynamics of rivers. It is claimed that the term torque was introduced into English scientific literature by Thomson, in 1884. [6]
James Thomson's main published research reports in physics and engineering were republished as a 500-page collection after his death. The collection is freely available online (see below) and is prefaced by a lengthy (80-page) biography plus a more concise (10-page) biography. It is stated in this book that Thomson is the first to use the words radian , interface and apocentric in English, though he used a number of other neologisms that have not survived.
William Thomson, 1st Baron Kelvin, was a British mathematician, mathematical physicist and engineer born in Belfast. He was the professor of Natural Philosophy at the University of Glasgow for 53 years, where he undertook significant research and mathematical analysis of electricity, was instrumental in the formulation of the first and second laws of thermodynamics, and contributed significantly to unifying physics, which was then in its infancy of development as an emerging academic discipline. He received the Royal Society's Copley Medal in 1883 and served as its president from 1890 to 1895. In 1892, he became the first British scientist to be elevated to the House of Lords.
Sir James Dewar was a British chemist and physicist. He is best known for his invention of the vacuum flask, which he used in conjunction with research into the liquefaction of gases. He also studied atomic and molecular spectroscopy, working in these fields for more than 25 years.
James Prescott Joule was an English physicist, mathematician and brewer, born in Salford, Lancashire. Joule studied the nature of heat, and discovered its relationship to mechanical work. This led to the law of conservation of energy, which in turn led to the development of the first law of thermodynamics. The SI derived unit of energy, the joule, is named after him.
Peter Guthrie Tait was a Scottish mathematical physicist and early pioneer in thermodynamics. He is best known for the mathematical physics textbook Treatise on Natural Philosophy, which he co-wrote with Lord Kelvin, and his early investigations into knot theory.
William John Macquorn Rankine was a Scottish mathematician and physicist. He was a founding contributor, with Rudolf Clausius and William Thomson, to the science of thermodynamics, particularly focusing on its First Law. He developed the Rankine scale, a Fahrenheit-based equivalent to the Celsius-based Kelvin scale of temperature.
Charles Thomson Rees Wilson, was a Scottish physicist and meteorologist who won the Nobel Prize in Physics for his invention of the cloud chamber.
Thomas Andrews FRS FRSE was an Irish chemist and physicist who did important work on phase transitions between gases and liquids. He was a longtime professor of chemistry at Queen's University of Belfast.
Sir Joseph Larmor was an Irish and British physicist and mathematician who made breakthroughs in the understanding of electricity, dynamics, thermodynamics, and the electron theory of matter. His most influential work was Aether and Matter, a theoretical physics book published in 1900.
Cargill Gilston Knott FRS, FRSE LLD was a Scottish physicist and mathematician who was a pioneer in seismological research. He spent his early career in Japan. He later became a Fellow of the Royal Society, Secretary of the Royal Society of Edinburgh, and President of the Scottish Meteorological Society.
John Macintyre or Mcintyre FRSE was a Scottish medical doctor who set up the world's first radiology department at the Glasgow Royal Infirmary, in Glasgow.
Andrew Gray was a Scottish physicist and mathematician.
John Aitken, FRS, FRSE LLD was a Scottish meteorologist, physicist and marine engineer. He was one of the founders of cloud physics and aerosol science, who built the first apparatus to measure the number of dust and fog particles in the atmosphere, a koniscope.
Harold Albert Wilson FRS was an English physicist.
The Institution of Engineers and Shipbuilders in Scotland (IESIS) is a multi-disciplinary professional body and learned society, founded in Scotland, for professional engineers in all disciplines and for those associated with or taking an interest in their work. Its main activities are an annual series of evening talks on engineering, open to all, and a range of school events aimed at encouraging young people to consider engineering careers.
James Thomson was an Irish mathematician, notable for his role in the formation of the thermodynamics school at the University of Glasgow. He was the father of the engineer and physicist James Thomson and the physicist Lord Kelvin.
Archibald Barr LLD, FRS FRSE was a Scottish scientific engineer, inventor and businessman. He was a co-founder of Barr & Stroud, and invented the Barr & Stroud Rangefinder.
James Thomson Bottomley was an Irish-born British physicist.
Dr Andrew Freeland Fergus FRSE LLD (1858–1932) was a Scottish ophthalmic surgeon. He was President of the Royal College of Surgeons in Glasgow, President of the Chirurgical Society, President of the Royal Philosophical Society of Glasgow, and President of the Greenock Faculty of Medicine.
William Jack FRSE was a Scottish mathematician and journalist. He was Editor of the Glasgow Herald newspaper from 1870 to 1876, and Professor of Mathematics at the University of Glasgow from 1879 until 1909.
Prof Magnus Maclean FRSE MIEE MICE LLD (1857-1937) was an electrical engineer who assisted Lord Kelvin in his electrical experiments and later became Professor of Electrical Engineering in Glasgow. The Magnus Maclean Memorial Prize given to students of electrical engineering is named in his honour. A native speaker of Scottish Gaelic, he also lectured in Celtic Studies at the University of Glasgow, delivering the MacCallum lectures, in English between 1901 and 1903. These lectures constituted the first official lectures in Celtic studies at the University.
