Lord Kelvin

Here is the revised memorial biography of William Thomson, 1st Baron Kelvin, incorporating only facts securely supported by reliable sources:

---

William Thomson, 1st Baron Kelvin was born on 26 June 1824 in Belfast, Ireland, the second son of James Thomson, a professor of mathematics, and his wife Margaret. His precise birthplace, College Square East, Belfast, and family background are confirmed in both the Dictionary of National Biography and other authoritative biographies (en.wikisource.org).

He and his elder brother moved to Glasgow in 1832 when their father accepted a professorship at the University of Glasgow. William’s early education was managed by his father at home; remarkably, he matriculated at the University of Glasgow at age ten. He later attended Peterhouse, Cambridge, beginning in 1841, where he graduated as Second Wrangler and First Smith’s Prizeman in 1845 (en.wikisource.org).

At just 22, in 1846, he became Professor of Natural Philosophy at the University of Glasgow, a position he held for 53 years until 1899 (en.wikipedia.org). During his distinguished tenure, Thomson made groundbreaking contributions in thermodynamics—helping to formulate the first and second laws—and in the mathematical analysis of electricity, among many other areas of physics (en.wikipedia.org).

He received the Royal Society’s Copley Medal in 1883 and served as its President from 1890 to 1895 (en.wikipedia.org). Knighted in 1866 for his scientific role in the transatlantic telegraph project, he became the first scientist elevated to the peerage in 1892 as Baron Kelvin, of Largs in the County of Ayr—his title inspired by the River Kelvin near his Glasgow laboratory (en.wikipedia.org). He introduced the absolute temperature scale, later named “kelvin” in his honor, and estimated the value of absolute zero at approximately –273.15 °C (en.wikipedia.org).

In later years, Kelvin served as Chancellor of the University of Glasgow from 1904 until his death. He died on 17 December 1907 at his home, Netherhall, near Largs, and his funeral took place in Westminster Abbey, where he was interred (universitystory.gla.ac.uk).
