The life of Airy was essentially that of a hard-working, business man, and differed from that of other hard-working people only in the quality and variety of his work. It was not an exciting life, but it was full of interest, and his work brought him into close relations with many scientific men, and with many men high in the State. His real business life commenced after he became Astronomer Royal, and from that time forward, during the 46 years that he remained in office, he was so entirely wrapped up in the duties of his post that the history of the Observatory is the history of his life.

Sir George Biddell Airy was an English mathematician and astronomer. He is regarded for his service as an Astronomer Royal from 1835 to 1881, and for being an influential advisor to the British Government.
Background
George Biddell Airy was born on July 27, 1801, at Alnwick, one of a long line of Airys who traced their descent back to a family of the same name residing at Kentmere, in Westmorland, in the 14th century. George Airy was the eldest of four children of William Airy, a farmer who through self-education acquired posts in the Excise, and of Ann Biddell, daughter of Ann a farmer from Suffolk.
At the age of twelve Airy came to know his uncle Arthur Biddell, a well-educated and highly respected farmer near Ipswich. He recognized in his uncle an opportunity to escape what he considered unpromising surroundings, and secretly requested that he be removed from his family. Arthur Biddell almost literally kidnapped him, without any word to his parents, but because of financial difficulties caused by William Airy’s loss of his Excise post, the escape was not blocked. From 1814 to 1819 Airy spent nearly half of his time with his uncle. In later life he put great value on this connection, especially because of the resulting acquaintances, including Thomas Clarkson, the abolitionist, who could help his career.
Education
At the age of ten George Airy took first place at Byatt Walker’s school at Colchester but, as he himself records, because he had very little animal vitality, he was not a favorite with his schoolmates. In the school he thoroughly learned arithmetic, double-entry bookkeeping, and the use of the slide rule.
It was through Clarkson and Charles Musgrave, fellow of Trinity College, Cambridge, that he was entered as sizar of Trinity College in October 1819. Airy entered Cambridge with the determination to get on, and he was certainly equipped to do so. Although his own assessment of his abilities was immodestly high, it was nevertheless matched, albeit sometimes reluctantly, by his tutors and college friends. He graduated as a Senior Wrangler in 1823 after far outdistancing all the men of his year, although beginning in his second term he had the burden of supporting himself by taking pupils.
After the graduation as a Senior Wrangler in 1823 from the Trinity College, George Airy was elected a fellow of Trinity College in 1824.
In 1824 an attempt was made to improve the educational level of assistants at the Royal Observatory by hiring one or two Cambridge graduates. Airy was proposed as one of these assistants and traveled to Greenwich to investigate the possibility. However, in his own words, “when I found that succession to the post of Astronomer Royal was not considered as distinctly a consequence of it, I took it cooly and returned to Cambridge the next night.”
Airy applied for and won the Lucasian professorship in 1826. In doing this, he exchanged an assistant tutorship worth £150 per annum, and the prospect of succeeding to a tutorship, for the £99 per annum of the professorship, supplemented by a somewhat uncertain £100 per annum as ex officio member of the Board of Longitude. Other considerations were that “my prospects in the law or other profession might have been good if I could have waited but marriage would have been out of the question and I much preferred a moderate income in no long time. 1 had now in some measure taken science as my line (though not irrevocably) and 1 thought it best to work it well for a time at least and wait for accidents.”
The Plumian professorship, which involved the care of the Cambridge Observatory, became vacant in 1828, and Airy “made known that I was a candidate and nobody thought it worthwhile to oppose me. ... I told everybody that the salary (about £300) was not sufficient and drafted a manifesto to the University for an increase. . . . the University had never before been taken by storm in such a manner and there was some commotion about it. I believe very few people would have taken the same step ... I had no doubt of success.” He was appointed Plumian professor and director of the observatory on 6 February 1828, with a salary of £500 per annum. Although he accepted the post of astronomer royal in 1835, when he moved from Cambridge to Greenwich, Airy’s considerable influence on British astronomy stretches without break from his appointment at Cambridge in 1828 to his retirement as astronomer royal in 1881. He was knighted in 1872, after thrice refusing on the basis that he could not afford the fees.
The rise of astronomy in the seventeenth and eighteenth centuries took the form of careful observations of stellar positions made to provide a framework within which planetary motions could be measured. The first astronomer royal, John Flamsteed, provided the earliest observations of this kind that are still useful today. Although the emphasis in modern astronomy has shifted beyond the planets to the stars and external galaxies, these early observations provide us with a three-hundred-year base line for measuring the motions of the stars themselves, and knowledge of these motions is vital to the understanding of the origin and evolution of the stars. Observations of this kind are not only necessary in large numbers but they must be extremely exacting if the results are to be of general use. They are therefore best made in a routine way by those more interested in the technological problems of their procurement than in their scientific use. The Royal Greenwich Observatory, following Flamsteed’s early lead, became the primary producer of such observations, mainly because the Admiralty was interested in the more immediate need of them lor navigational purposes. Partly because the utilitarian purpose was stressed, scientific supervision of the observations eventually decreased and was refocused only in the nineteenth century, when it became obvious that their lack of accuracy was adversely affecting their use in navigation. The situation was ripe for Airy with his scientific training and his sense of order. The reforms he introduced were copied by other countries that, because they were expanding their navies to protect their expanding merchant fleets, needed the navigational aids.
In any article on Airy mention must be made of the controversy accompanying the discovery of the planet Neptune. It is ironical that the kind of order Airy restored to the observational work at Greenwich should coincide with the greatest need for the results since Newton had put Flamsteed’s observations to such good use in the Principia - and then be unfairly blamed in nearly every subsequent article on the discovery of Neptune for withholding these observations. In fact, Airy supplied all the major participants in this discovery with the observational data they requested, and the only basis for the subsequent attacks upon him was that he was not at home when John Adams, then a young Cambridge mathematician, called unannounced to present one of his early predictions that such a planet as Neptune had to exist in order to account for the motions of the other planets. Airy’s great efficiency in the observatory was noted by other government services and he rapidly became the prototype of the modern government scientist. This kept him from the observatory a large amount of time.
As he was by nature eminently practical, and his dislike of mere theoretical problems and investigations put him continually in dissent with some of the resident Cambridge mathematicians. This practical bent led him to undertake, in 1872, the preparation of a numerical lunar theory. This work consisted, essentially, of obtaining from observations numerical values of the 320 periodic terms in Delaunay’s equations for the moon’s motion.
Airy was not a great scientist, but he made great science possible. It is true that he was indirectly responsible for guiding British observational astronomy into a cul-de-sac from which it took many years to retreat, but it was not his fault that the methods he devised to provide a particular service at a particular time were so efficiently contrived and completely implemented that weaker successors continued to apply them, unchanged, to changing conditions.
In his religious affiliation Airy was a Roman Catholic. He was fascinated by the architecture of churches and visited nearly all the cathedrals and principal churches in England. He was a great reader of theology and church history, and as regarded forms of worship and the interpretation of the Scriptures, he treated them with great respect, but from the point of view of a freethinking layman.
Politics
Since George Airy dedicated his whole life to science and astronomy, he wasn`t heavily involved in the ongoing political affairs of his time. However, in his views Airy was strongly liberal. When he was appointed to the post of Astronomer Royal, he stipulated that he should not be asked to vote in any political election. But all his views were in the liberal direction.
Views
The secret of Airy’s long and successful official career was that he was a good servant who thoroughly understood his position. He never set himself in opposition to his masters, the Admiralty. He recognized the task for which he was appointed and transformed the Royal Greenwich Observatory into a highly efficient institution. The cost, however, was high. No independent thought could be tolerated, and as a result no scientists were trained there. The often slipshod methods that lead to scientific discovery were carried on outside, by John Herschel, John Adams, and many others. Airy himself would not understand this criticism. He wrote, in 1832, “. . . in those parts of astronomy which depend principally on the assistance of Governments, requiring only method and judgement, with very little science in the persons employed, we have done much; while in those which depend exclusively on individual effort we have done little. . . . our principal progress has been made in the lowest branches of astronomy while to the higher branches of science we have not added anything.” He needed only to add that he had done his job.
Quotations:
In 1890 he tells us how a grievous error had been committed in one of the first steps, and pathetically adds, " My spirit in the work was broken, and I have never heartily proceeded with it since. "
"In the hands of Science and indomitable energy, results the most gigantic and absorbing may be wrought out by skilful combinations of acknowledged data and the simplest means."
"I had made considerable advance ... in calculations on my favourite numerical lunar theory, when I discovered that, under the heavy pressure of unusual matters (two transits of Venus and some eclipses) I had committed a grievous error in the first stage of giving numerical value to my theory. My spirit in the work was broken, and I have never heartily proceeded with it since."
"On Sept 15th (1852) Mr Goulburn, Chancellor of the Exchequer, asked my opinion on the utility of Mr Babbage's calculating machine, and the propriety of spending further sums of money on it. I replied, entering fully into the matter, and giving my opinion that it was worthless."
His difficulties on the preparation of a numerical lunar theory are summed up in a note of 29 September 1890:
"I had made considerable advance (under official difficulties) in calculations on my favourite Numerical Lunar Theory, when I discovered that, under the heavy pressure of unusual matters (two Transits of Venus and some eclipses) I had committed a grievous error in the first stage of giving numerical value to my Theory. My spirit in the work was broken, and I have never heartily proceeded with it since."
Membership
The Royal Astronomical Society elected Airy to be their President in 1845. Then, in 1851, Airy was elected President of the British Association, and in 1871 he was elected President of the Royal Society of London holding the post for two years.
Personality
At his youth George was an introverted but not shy child, even for the time and especially for his circumstances, a young snob. Nevertheless, he overcame some of the dislike of his schoolmates by his great skill and inventiveness in the construction of peashooters and other such devices.
Later in life, when he served as a Lucasian professor of mathematics at the Trinity College, Cambridge, there were three incidents from this period that vividly illustrate his personality and the care, as well as the foresight with which Airy planned his life. The first concerns the habit he adopted, as an undergraduate, of always keeping by him a quire of largesized scribbling paper, sewn together, upon which everything was entered: translations into Latin and out of Greek, several lines of which he attempted every day, no matter how pressing other business might be; mathematical problems; and nearly every thought he had, complete with date. The sheets, even after the more important items were transferred to exercise books or diaries, were kept, together with nearly every communication received and a copy of those sent throughout his life, and are still extant. He seems not to have destroyed a document of any kind whatever: stubs of old checkbooks, notes for tradesmen, circulars, bills, and correspondence of all sorts were carefully preserved in chronological order from the time that he went to Cambridge. This material provides possibly the best existing documentation of a truly Victorian scientist.
The second illustrative incident involves Airy’s courtship of his future wife, Ricarda Smith, the eldest daughter of the Rev. Richard Smith, private chaplain to the duke of Devonshire. He met Miss Smith while he was on a walking tour in Derbyshire, and within two days of first seeing her he made an offer of marriage. Neither his means nor his prospects at the time permitted an immediate marriage, and the Rev. Smith would not permit an engagement. Undaunted, Airy' renewed his suit from time to time, and six years after his first proposal they were married.
A similar singleness of purpose is shown in Airy’s approach to a prospective position at the Royal Greenwich Observatory. The ruling feature of Airy’s character was undoubtedly order, and from the time he went up to Cambridge until the end of his life his system of order was strictly maintained. He wrote his autobiography up to date as soon as he had taken his degree, and made his first will as soon as he had any money to leave. His accounts were personally kept by double entry, and he regarded their keeping as one of his greatest joys. The effect of this sense of order on British observational astronomy is the only reason that Airy is included in this volume, for he was an organizer rather than a scientist. To realize his importance, it is necessary to understand the astronomy of the nineteenth century and the role played by such institutions as the Royal Greenwich Observatory.
His memory was singularly retentive. It was much remarked at school in his early days, and in the course of his life he had stored up in his memory an incredible quantity of poetry, ballads, and miscellaneous facts and information of all sorts, which was all constantly ready and at his service. It is almost needless to add that his memory was equally accurate and extensive in matters connected with science or business.
His independence of character was no doubt due to and inseparable from his great powers. The value of his scientific work greatly depended upon his self-reliance and independence of thought. And in the heavy work of remodelling the Observatory it was a very valuable quality. This same self-reliance made him in his latter years apt to draw conclusions too confidently and hastily on subjects which he had taken up more as a pastime than as work. But whatever he touched he dealt with ably and in the most fearless truthseeking manner, and left original and vigorous
opinions. He had a remarkably well-balanced mind, and a simplicity of nature that appeared invulnerable. No amount of hero worship seemed to have the least effect upon him.
His nature was eminently practical, and any subject which had a distinctly practical object, and could be advanced by mathematical investigation, possessed interest for him. And his dislike of mere theoretical problems and investigations was proportionately great. He was continually at war with some of the resident Cambridge mathematicians on this subject. An illustration of Airy's personality is shown from his long running disagreements with Babbage. They had a dispute over the quality of a telescope in 1832, he stated that Babbage 's calculating engine was "worthless" ten years later and effectively stopped government funding of the project, and in 1854 he took the side of the narrow gauge for railways while Babbage supported the wide gauge. In all these disputes Airy came out the winner, but it is far from clear that he took the "right" side in the arguments.
As his powers failed with age, he was tyrannized by his ruling passion for order, and his efforts went into correctly filing his correspondence rather than understanding its contents. To a high appreciation of order he attributed in a great degree his command of mathematics, and sometimes spoke of mathematics as nothing more than a system of order carried to a considerable extent. In everything he was methodical and orderly, and he had the greatest dread of disorder creeping into the routine work of the Observatory, even in the smallest matters.
At the same time he was sensible and shrewd in his money matters and attentive to his personal interests. And his practical good sense in the general affairs of life, combined with his calm and steady consideration of points submitted to him, made his advice very valuable. This was especially
recognized by his own and his wife's relations, who consulted him on many occasions and placed the fullest confidence in his absolute sense of justice as well as in his wise counsel.
He was extremely liberal in proportion to his means, and gave away money to a large extent to all who had any claim upon him. But he was not in any sense reckless, and kept a most cautious eye on his expenses. He was not indifferent to the honours which he received in the scientific world, but
he does not appear to have sought them in any way, and he certainly did not trouble himself about them.
His courtesy was unfailing : no amount of trouble could shake it. Whether it was the Secretary of the Admiralty, or a servant girl wanting her fortune told : whether a beggingletter for money, or miscellaneous invitations : all had their answer in the most clear and courteous language. But he
would not grant personal interviews when he could avoid it: they took up too much of his time. His head was so clear that he never seemed to want for the clearest and most direct language in expressing his meaning, and his letters are models of terseness.
Physical Characteristics:
Always of medium stature and not powerfully built, Airy seemed to shrink as he aged, mainly because of an increasing stoop. His constitution, even at eighty- five, was remarkably sound. He took not the least interest in athletic sports or competition, but he was always a very active walker and could endure a great deal of fatigue.
His eye-sight was peculiar, and required correction by spectacles the lenses of which were ground to peculiar curves according to formulae which he himself investigated: with these spectacles he saw extremely well, and he commonly carried three pairs, adapted to different distances: he took great interest in the changes that took place in his eye-sight and wrote several Papers on the subject.
Quotes from others about the person
Newton pointed out and assigned generally, not only the nature and the magnitude of the periodical forces which are concerned in producing the tides, but likewise indicated their true character as undulations, in one very remarkable proposition, as well as in a special explanation of... the tides of the Port of Batsha. The equilibrium theory of Daniel Bernoulli adopted the first part of Newton's views but altogether neglected the second:
"...Professor Airy ...has pronounced the theory proposed by La Place in the Mécanique Céleste,—if viewed with reference to the boldness and comprehensive character of its design rather than to the success of its execution—"as one of the most splendid works of the greatest mathematician of the past age." The problem, however, was not considered by [La Place] in the most general form which it is capable of receiving. He assumed the earth to be entirely covered by water, and its depth to be uniform, at least throughout the same parallel of latitude, and he neglected the resistance both of the particles of the fluid amongst each other, and of that which arises from the irregular surfaces in the channels over which the tide is transmitted. He was consequently obliged to omit the consideration of the tides in canals, rivers, and narrow seas, which constitute some of the most interesting, and by no means the most unmanageable, of the problems which later, and even in some respects more simple, investigations of the oscillations of the sea have brought within the control of analysis. Imperfect, however, as the results of this theory were as it came from the hand of its author, their importance cannot easily be estimated too highly. Dr. Young adopted the general principles which they involved, though he has subjected them to a totally different treatment; and Professor Airy, who has materially simplified the investigations which it contains, by rejecting some conditions which they included, such as the density of the sea, by which they were made needlessly difficult and complicated, has not only verified the more remarkable of the conclusions at which La Place arrived, but has also made important use of his methods in his own theory of waves and tides, which is by far the most complete and comprehensive that has ever yet appeared."
Interests
Outside his professional scientific interests, Airy was a man of broad tastes. He liked poetry, history, theology, antiquities, architecture, engineering, and geology. He even published papers on his other interests including one which tried to identify the exact place where Julius Caesar landed in Britain and the exact place from which he left. In addition he published a number of papers on religious matters.
Airy was very fond of music and knew a great number of songs; and he was well acquainted with the theory of music: but he was no performer. Also, Antiquities and Architecture were very favourite subjects with him. He had visited most of the camps and castles in the United Kingdom and was never tired of tracing their connection with ancient military events: and he wrote several Papers on this subject, especially those relating to the Roman Invasions of Britain. Ecclesiastical Architecture he was very fond of: he had visited nearly all the cathedrals and principal churches in England, and many on the Continent...
Connections
In July 1824, Airy met Richarda Smith (1804–1875), "a great beauty", on a walking tour of Derbyshire. He later wrote, "Our eyes met . .. and my fate was sealed . .. I felt irresistibly that we must be united, " and Airy proposed two days later. Richarda's father, the Revd Richard Smith, felt that Airy lacked the financial resources to marry his daughter. Only in 1830, with Airy established in his Cambridge position, was permission for the marriage granted.
The Airys had nine children, the eldest three dying in childhood. The eldest survivor, Wilfrid Airy, was the designer and engineer for "Colonel" George Tomline's Orwell Park Observatory. Wilfrid's daughter was the artist Anna Airy. Their son Hubert Airy (1838–1903) was a doctor, and a pioneer in the study of migraine. Their eldest daughter, Hilda (1840–1916), married the mathematician Edward Routh in 1864.
The Neptune File: A Story of Astronomical Rivalry and the Pioneers of Planet Hunting
The Neptune File is the first full account of the dramatic events surrounding the eighth planet's discovery, and the story of two remarkable men who were able to "see" on paper what astronomers looking through telescopes for more than 200 years had overlooked. On June 26, 1841, John Couch Adams, a brilliant young mathematician at Cambridge University, chanced upon a report by England's Astronomer Royal, George Airy, describing unsuccessful attempts to explain the mystifying orbital behavior of the planet Uranus, discovered 65 years earlier. Adams theorized that Uranus's orbit was being affected by the gravitational pull of another, as-yet-unseen planet. Furthermore, he believed that he did not need to see the planet to know where it was. Four years later, his daring mathematical calculations pinpointed the planet's location, but Airy failed to act on them―a controversial lapse that would have international repercussions. Soon after Adams's "proof," a rival French astronomer, Urbain Le Verrier, also calculated the planet's position, and the race was on to actually view it. Found just where Adams and Le Verrier had predicted, the planet was named Neptune―and as the first celestial object located through calculation rather than observation, its discovery pioneered a new method for planet hunting. Drawing on long-lost documents in George Airy's Neptune scrapbook, which resurfaced mysteriously at an observatory in Chile in 1999, The Neptune File is a crackling good human drama and a fascinating exploration of the science that underpins planetary astronomy. And the tale continues to unfold, as Tom Standage relates: Since 1995, astronomers have discovered more than 40 planets outside our solar system, opening an intriguing window on the universe. Yet none of these planets have ever been seen. Their discovery―and the history of science―owes much to the two men who unlocked the secret to locating unseen new worlds.
In 1876 Airy was awarded the Albert Medal by Royal Society of Arts.
