Naylor Prize and Lectureship (1981)
He was educated at The Pilgrims' School, Winchester, and Winchester College. In 1941, he won a scholarship to Balliol College, Oxford. He read chemistry, but also took Part I of a degree in Music. He was a Balliol organ scholar.
As an undergraduate he proposed the correct structure of the chemical compound diborane (B2H6), which was then unknown because it turned out to be different from structures in contemporary chemical valence theory. This was published with his tutor, R. P. Bell. He completed a DPhil at the University of Oxford under the supervision of Charles Coulson. This was followed by post-doctoral work at the University of Chicago and the University of Manchester.
In 1952, he was appointed Professor of Theoretical Physics at King's College, London, and in 1954 became John Humphrey Plummer Professor of Theoretical Chemistry at Cambridge, and a Fellow of Corpus Christi College. He became interested in the brain and the new field of artificial intelligence. As a consequence, in 1967, he made a major change in his career by moving to the University of Edinburgh to co-found the Department of Machine intelligence and perception, with Richard Gregory and Donald Michie.
He later moved to the experimental psychology department at Sussex University, Brighton, England. In 1981 he introduced the essential matrix to the computer vision community in a paper which also included the eight-point algorithm for the estimation of this matrix. He retired in 1988. At the time of his death, in 2004, he was Professor Emeritus at the University of Sussex.
Longuet-Higgins died on 27 March 2004, aged 80.
His work on developing computational models of music understanding was recognized in the nineties by the award of an Honorary Doctorate of Music by Sheffield University.
Longuet-Higgins et al (1994): —
- You're browsing, let us imagine, in a music shop, and come across a box of faded pianola rolls. One of them bears an illegible title, and you unroll the first foot or two, to see if you can recognize the work from the pattern of holes in the paper. Are there four beats in the bar, or only three? Does the piece begin on the tonic, or some other note? Eventually you decide that the only way of finding out is to buy the roll, take it home, and play it on the pianola. Within seconds your ears have told you what your eyes were quite unable to make out—that you are now the proud possessor of a piano arrangement of "Colonel Bogey".

Honors and awards
- In 2005 the "Longuet-Higgins Prize for Fundamental Contributions in Computer Vision that Have Withstood the Test of Time" was created in his honor.
- The prize is awarded every year at the IEEE Computer Vision and Pattern Recognition Conference for up to two distinguished papers published at that same conference ten years earlier.
- He was a Fellow of the Royal Society and of the International Academy of Quantum Molecular Science.
His younger brother is Michael S. Longuet-Higgins.
