Education across Scotland and Cambridge
Maxwell was born in Edinburgh on 13 June 1831 and grew up largely at Glenlair. His education took him through Edinburgh Academy, the University of Edinburgh, and Cambridge. After beginning at Peterhouse in 1850, he moved to Trinity College; the 1854 Mathematical Tripos marked his emergence as a mathematical researcher.
He held the natural-philosophy chair at Marischal College, Aberdeen, from 1856 to 1860, and married Katherine Mary Dewar in 1858. A subsequent appointment at King’s College London placed him in another setting for work on physics before his return to Cambridge.

A field connected electricity, magnetism and light
His 1865 paper, A Dynamical Theory of the Electromagnetic Field, made the surrounding field central to the mathematical account. The Smithsonian’s original-publication record distinguishes its 1865 publication from the Royal Society presentation in 1864. The argument connected electromagnetic disturbances with light.
Modern textbook equations bearing Maxwell’s name should not be treated as a photograph of his original notation. His work developed through a sequence of papers and his 1873 Treatise on Electricity and Magnetism. It built on experimental and theoretical predecessors rather than making instruments, measurements and collaborators unnecessary.
More than one famous theory
Maxwell also worked on the stability of Saturn’s rings, the behaviour of gases and colour reproduction. His 1860 paper on the dynamical theory of gases belongs to the history of statistical descriptions, while his work on governors addressed feedback in mechanical systems. These projects used different models to ask different questions.
This range helps explain why a biography limited to a list of four modern equations loses much of his career. The Foundation’s chronological record separates scientific papers, appointments and honours instead of treating them as interchangeable signs of genius.

Building a place for experimental physics
In 1871 Maxwell became Cambridge’s first Cavendish Professor of Experimental Physics. He oversaw the design and construction of the laboratory that opened in 1874 with William Cavendish’s benefaction. Appointment, building and opening were separate stages.
Maxwell died in 1879, aged 48. The Cambridge departmental history credits his role in creating the laboratory, while identifying systematic experimental instruction under his successor, Lord Rayleigh. His legacy therefore includes both theoretical work and an institution that others continued to develop.
