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 George Francis FitzGerald, Academic & Physicist

Professor George Francis FitzGerald FRS FRSE, Irish academic and physicist, is born at No. 19, Lower Mount Street in Dublin on August 3, 1851. He is known for his work in electromagnetic theory and for the Lorentz–FitzGerald contraction, which becomes an integral part of Albert Einstein‘s special theory of relativity.

FitzGerald is born to the Reverend William FitzGerald and his wife Anne Frances Stoney. He is the nephew of George Johnstone Stoney, the Irish physicist who coins the term “electron.” After the particles are discovered by J. J. Thomson and Walter Kaufmann in 1896, FitzGerald is the one to propose calling them electrons. He is also the nephew of Bindon Blood Stoney, an eminent Irish engineer. His cousin is Edith Anne Stoney, a pioneer female medical physicist.

Professor of Moral Philosophy at Trinity College Dublin and vicar of St. Anne’s, Dawson Street, at the time of his son’s birth, William FitzGerald is consecrated Bishop of Cork, Cloyne and Ross in 1857 and translates to Killaloe and Clonfert in 1862. George returns to Dublin and enters TCD as a student at the age of sixteen, winning a scholarship in 1870 and graduating in 1871 in Mathematics and Experimental Science. He becomes a Fellow of Trinity in 1877 and spends the rest of his career there, serving as Erasmus Smith’s Professor of Natural and Experimental Philosophy from 1881 to 1901.

Along with Oliver Lodge, Oliver Heaviside and Heinrich Hertz, FitzGerald is a leading figure among the group of “Maxwellians” who revise, extend, clarify, and confirm James Clerk Maxwell‘s mathematical theories of the electromagnetic field during the late 1870s and the 1880s.

In 1883, following from Maxwell’s equations, FitzGerald is the first to suggest a device for producing rapidly oscillating electric currents to generate electromagnetic waves, a phenomenon which is first shown to exist experimentally by the German physicist Heinrich Hertz in 1888.

In 1883, FitzGerald is elected Fellow of the Royal Society. In 1899, he is awarded a Royal Medal for his investigations in theoretical physics. In 1900, he is made an honorary fellow of the Royal Society of Edinburgh.

FitzGerald is better known for his conjecture in his short letter to the editor of Science. “The Ether and the Earth’s Atmosphere” explains that if all moving objects were foreshortened in the direction of their motion, it would account for the curious null-results of the Michelson–Morley experiment. He bases this idea in part on the way electromagnetic forces are known to be affected by motion. In particular, he uses some equations that had been derived a short time before by his friend the electrical engineer Oliver Heaviside. The Dutch physicist Hendrik Lorentz hits on a very similar idea in 1892 and develops it more fully into Lorentz transformations, in connection with his theory of electrons.

The Lorentz–FitzGerald contraction hypothesis becomes an essential part of the Special Theory of Relativity, as Albert Einstein publishes it in 1905. He demonstrates the kinematic nature of this effect, by deriving it from the principle of relativity and the constancy of the speed of light.

FitzGerald suffers from many digestive problems for much of his shortened life. He becomes very ill with stomach problems. He dies on February 22, 1901, at his home, 7 Ely Place in Dublin, the day after an operation on a perforated ulcer. He is buried in Mount Jerome Cemetery.

A crater on the far side of the Moon is named after FitzGerald, as is a building at Trinity College Dublin.
