Death of Edward Hutchinson Synge, Irish Physicist

Irish physicist Edward Hutchinson Synge dies in a Dublin nursing home on May 26, 1957. He publishes a complete theoretical description of the near-field scanning optical microscope, an instrument used in nanotechnology, several decades before it is experimentally developed. He never completes university yet does significant original research in both microscopy and telescopy. He is the first to apply the principle of scanning in imaging, which later becomes important in a wide range of technologies including television, radar, and scanning electron microscopy.

Synge is born on June 1, 1890, in south Dublin, to Edward Synge and Ellen Frances Price. He is familiarly known as “Hutchie.” He is the nephew of playwright John Millington Synge and the older brother of distinguished mathematician and theoretical physicist John Lighton Synge who edits the collected works of Sir William Rowan Hamilton at Synge’s urging. He and brother John are great-great-great-grandsons of Irish bishop Hugh Hamilton. He is also the uncle of the mathematician Cathleen Synge Morawetz. Throughout his life he is very physically active, pursuing walking, cycling, swimming and sailing. In his later life, he takes up painting and is quite good at it.

In 1908, Synge enters Trinity College Dublin (TCD) to study Mathematics and Old Irish. For three years he is a brilliant student and wins several prizes and a Foundation Scholarship in mathematics in 1910. At the end of his third year, he comes into an inheritance from his uncle John Millington Synge, and in 1913 he drops out of university.

Starting in 1928, with encouragement from Albert Einstein, Synge launches on a period of intense productivity during which he lays the foundation for new kinds of microscopes and telescopes. Nobody, including his famous brother John, appreciates his achievements at the time. His work is overlooked for decades, but is now better-known thanks to the book The Life and Works of Edward Hutchinson Synge published by Living Edition in 2012.

On April 22, 1928, Synge writes to Einstein about an idea he has for a new microscopic imaging method in which an optical field scattered from a tiny gold particle can be used as a radically new light source. Einstein replies that although Synge’s method appears essentially unworkable, the basic ideas seem correct and he should publish his research.

There follows a remarkable period from 1928 to 1932 in which Synge produces all of his key works which he publishes in the Dublin Philosophical Magazine and Journal of Science. Remarkably, he does all of this work alone, without a laboratory, and while living at his home in Dundrum in the suburbs of Dublin. By 1932 he has laid out the theory of the near-field microscope and his description is incredibly accurate.

The idea is ahead of its time. In 1956, a similar theory is developed by John A. O’Keefe and in 1972, Eric Ash gives the first experimental demonstration of the technique using electromagnetic radiation. It is not until Synge’s original papers re-emerge in the 1980s that his priority is finally recognised.

Synge proposes a design for very large astronomical telescopes, based on multiple mirrors, an idea realised much later in Tucson, Arizona, and elsewhere. He also invents a new kind of remote sensing technique using searchlights. Today this is known as Lidar and uses pulsed lasers.

According to the people who know him best, Synge suffers from what today would be called Asperger syndrome. Becoming increasingly socially isolated, he drops out of university in 1913 and works alone without any support from the academic community until all work stops in 1932. In 1936, he has a mental breakdown and is committed to a Dublin nursing home where he remains until his death on May 26, 1957. He is buried with his parents in Dublin’s Mount Jerome Cemetery, with only a few relatives attending. It is much later that his niece, Cathleen Synge Morawetz, arranges to have “Scientist and Inventor” inscribed on the gravestone.

Birth of John Lighton Synge, Mathematician & Physicist

John Lighton Synge FRSC FRS, mathematician and physicist, whose seven-decade career includes significant periods in Ireland, Canada, and the United States, is born in Dublin on March 23, 1897. He is a prolific author and influential mentor and is credited with the introduction of a new geometrical approach to the theory of relativity.

Synge is born into a prominent Church of Ireland family. His uncle, John Millington Synge, is a famous playwright. He is more distantly related to the winner of the 1952 Nobel Prize in Chemistry, Richard Laurence Millington Synge. He is a great-great-great-grandson of the mathematician and bishop Hugh Hamilton.

Synge attends St. Andrew’s College, Dublin and in 1915 enters Trinity College Dublin (TCD). He is elected a Foundation Scholar his first year, which is unusual as it is normally won by more advanced students. While an undergraduate at TCD, he spots a non-trivial error in Analytical Dynamics of Particles and Rigid Bodies, a textbook by E. T. Whittaker, who had recently taught there, and notifies Whittaker of the error. In 1919 he is awarded a BA in Mathematics and Experimental Physics, and also a gold medal for outstanding merit. In 1922 he is awarded an MA, and in 1926 a Sc.D., the latter upon submission of his published papers up to then.

In 1918, Synge marries Elizabeth Eleanor Mabel Allen. She is also a student at TCD, first of mathematics, then of history, but family finances forced her to leave without graduating. Their daughters Margaret (Pegeen), Cathleen and Isabel are born in 1921, 1923 and 1930 respectively. The middle girl grows up to become the distinguished Canadian mathematician Cathleen Synge Morawetz.

Synge is appointed to the position of lecturer at Trinity College, and then accepts a position at the University of Toronto in 1920, where he is an assistant professor of mathematics until 1925. There he attends lectures by Ludwik Silberstein on the theory of relativity, stimulating him to contribute “A system of space-time co-ordinates,” a letter in Nature in 1921.

Synge returns to Trinity College Dublin, in 1925, where he is elected to a fellowship and is appointed the University Professor of Natural Philosophy (later to be known as “physics”). He is a member of the American Mathematical Society and the London Mathematical Society. He is treasurer of the Royal Irish Academy in 1929. He goes back to Toronto in 1930, where he is appointed Professor of Applied Mathematics and becomes Head of the Department of Applied Mathematics. In 1940, he supervises three Chinese students, Guo Yonghuai, Qian Weichang and Chia-Chiao Lin, who later become leading applied mathematicians in China and the United States.

Synge spends some of 1939 at Princeton University, and in 1941, he is a visiting professor at Brown University. In 1943 he is appointed as Chairman of the Mathematics Department of Ohio State University. Three years later he becomes Head of the Mathematics Department of the Carnegie Institute of Technology in Pittsburgh, where John Nash, Jr. is one of his students. He spends a short time as a ballistic mathematician in the United States Air Force between 1944 and 1945.

Synge returns to Ireland in 1948, accepting the position of Senior Professor in the School of Theoretical Physics at the Dublin Institute for Advanced Studies. This school had been set up in 1940, and had several outstanding members, including Erwin Schrödinger, a contributor to quantum mechanics, who is also a Senior Professor.

Synge makes outstanding contributions to different fields of work including classical mechanics, general mechanics and geometrical optics, gas dynamics, hydrodynamics, elasticity, electrical networks, mathematical methods, differential geometry, and Albert Einstein‘s theory of relativity. He studies an extensive range of mathematical physics problems, but his best-known work revolves around using geometrical methods in general relativity.

Synge is one of the first physicists to seriously study the interior of a black hole, and his early work is cited by both Martin David Kruskal and George Szekeres in their independent discoveries of the true structure of the Schwarzschild black hole. Synge’s later derivation of the Szekeres-Kruskal metric solution, which is motivated by a desire to avoid “using ‘bad’ coordinates to obtain ‘good’ coordinates,” has been generally under-appreciated in the literature, but is adopted by Chandrasekhar in his black hole monograph.

In pure mathematics, Synge is perhaps best known for Synge’s theorem, which concerns the topology of closed orientable Riemannian manifold of positive sectional curvature. When such a space is even-dimensional and orientable, the theorem says it must be simply connected. In odd dimensions, it instead says that such a space is necessarily orientable.

Synge also creates the game of Vish in which players compete to find circularity (vicious circles) in dictionary definitions.

Synge retires in 1972. He receives many honours for his works. He is elected as a fellow of the Royal Society of London in 1943. He is elected as a fellow of the Royal Society of Canada, and in 1943 is the first recipient of the society’s Henry Marshall Tory Medal, as one of the first mathematicians working in Canada to be internationally recognised for his research in mathematics. In 1954 he is elected an honorary fellow of Trinity College Dublin. He is president of the Royal Irish Academy from 1961 until 1964. The Royal Society of Canada establishes the John L. Synge Award in his honour in 1986.

Synge dies on March 30, 1995, in Dublin, exactly one week after his ninety-eighth birthday.
