Michael Selwyn Longuet-Higgins FRS (December 8, 1925 – February 26, 2016)[2] was a mathematician and oceanographer at the Department of Applied Mathematics and Theoretical Physics (DAMTP), Cambridge University, England and Institute for Nonlinear Science, University of California, San Diego, USA. He was the younger brother of H. Christopher Longuet-Higgins.
Longuet-Higgins introduced the theory of the origin of microseisms[3] and is the inventor of "rhombo blocks", a mathematical toy consisting of blocks whose faces are rhombuses.[4]

Synopsis
Michael S. Longuet-Higgins was a scientist and mathematician, who discovered and mathematically described many of the theoretical and physical models of ocean waves, currents and natural physical phenomena. He left a legacy of scientific and mathematical publications for the world of oceanography and mathematics, useful for describing the effects of the oceans on climate, sediment and water transport, structural engineering and natural phenomenon such as microseisms, sonoluminescence and underwater sound.
Educated at The Pilgrims' School, Winchester and at Winchester College from 1937 to 1941 together with Freeman Dyson, his brother Christopher, and James Lighthill from 1937 to 1943, he won a scholarship in mathematics at the age of 17 to Trinity College, Cambridge, where he qualified after just two years for a BA in mathematics in 1945. He was awarded a PhD in geophysics in 1951. From 1969 to 1989 he served as a Royal Society Research Professor at the University of Cambridge.
His research areas included both pure mathematics (projective geometry, polytopes, random functions and surfaces) and applied mathematics (fluid dynamics, microseisms, the generation of ocean waves by wind, the dynamics of bubbles, sonoluminescence, wave breaking, steep waves, and the exchange of heat and gases at the ocean surface).
Education and Career
Michael was born in Lenham, Kent in England to Henry Hugh Longuet Longuet-Higgins and Albinia Cecil Bazeley. He had an elder sister Patricia (Pat) and an elder brother Hugh Christopher (Christopher). He was educated at The Pilgrim's School, Winchester and at Winchester College together with Freeman Dyson, his brother Christopher, and James Lighthill from 1937 to 1943. In 1943, at the age of 17, he won a scholarship in mathematics to Trinity College, Cambridge where he qualified after just two years for a BA in mathematics in 1945. He was awarded a PhD in geophysics in 1951.[5]
Towards the end of the World War II (December 1943) he started working for the Admiralty Research Laboratory (ARL) in Teddington. He joined Group W (waves) set up on 5 June 1944 under George Deacon. Here he helped predict wave and currect conditions in preparation for the Pacific landings. He worked not only on the theory of wind waves but also on the geomagnetic induction of voltages by tidal streams, and on the generation of oceanic microseisms.
In 1948 he returned to Cambridge, to read for a PhD but without a break in his research, just reporting to Sir Harold Jeffreys and later to Robert Stoneley at the end of each term. After being awarded his PhD in geophysics ("just a one hour interview which he almost forgot to attend") in 1951 at Cambridge, he was awarded a 4-year research Fellowship (Title A) at Trinity College. The first year (1951-2) he spent in the USA as a Commonwealth Fund Fellow, first at the Woods Hole Oceanographic Institute on Cape Cod, Massachusetts, and then at the Scripps Institution of Oceanography at La Jolla, California, with Walter Munk. On his return to England in 1952, he spent two years of his Research Fellowship in Cambridge.
He was invited to join the National Institute of Oceanography in Witley, Surrey in 1954 (renamed Institute of Oceanographic Science in 1973) then lead by George Deacon, studying ocean waves and storm surges. He was elected as a Fellow of the Royal Society in 1963. During this period "of thirteen happy and fruitful years" he had several visiting research appointments, including the Mathematics Department at MIT (1957-8), the University of Adelaide, Australia (1964) and the University of California, San Diego (1961-2 and 1966-7). Between 1967 and 1969 he was Professor of Applied Mathematics and Oceanography at Oregon State University in Corvallis, Oregon.
From 1969 to 1989 he served as a Royal Society Research Professor at the University of Cambridge, working both in the Department of Applied Mathematics and Theoretical Physics (DAMPT), Cambridge, and at The National Institute of Oceanography, Witley. After his "retirement" in Cambridge in 1989 he moved to California and worked at the La Jolla Institute in San Diego. In 1991, he was appointed to the Institute for Nonlinear Science, University of California, San Diego (UCSD) as a Senior Research Physicist (known as "The Admiral"), and to the Scripps Institution with an Adjunct Professorship until his second "retirement" in 2001. After that he continued work at Scripps as a Research Physicist Emeritus. He remained active in research, at conferences and served on many committees.

Personal
Michael Longuet-Higgins was married to Joan Redmayne Tattersall on 12. December 1958. Together they had four children, Ruth, Mark, John and Anne all of whom were born in Guildford, England. The children were brought up during the first years in Godalming, England; Del Mar, Torry Pines and La Jolla, California; Corvallis, Oregon; Cambridge and Comberton in England.
His recreations included music (oboe and tenor recorder), gardening, and educational toys: While at Winchester he built a complete set of wire Polyhedra, now donated to and on permanent display at Winchester College. In 1953 he wrote a scientific paper on the properties of the Slinky.,[6] and in the 60's made a film on Mathematical Toys, starring his children. After being inspired by the discovery of quasicrystals and by his colleague Roger Penrose (Penrose tiling) he developed a 3-dimensional toy with 3 and 5 rotational symmetry, including a world-wide patented 4-pole magnetic connector, called Rhombo.

Michael Longuet-Higgins was widowed, in 2011. After leaving England in 1989, he lived with his partner Betty Backus in Del Mar and La Jolla, California until Betty's death in 2015. He returned to the family home, Gage Farm in England in late 2015 where he lived until he died in early 2016. His ashes are placed in the family vault in Turvey, England and spread on the Pacific Coast in La Jolla, USA.
