One of the main objects of [Glaisher and Coxwell's] ascents was to extend and improve our knowledge of the relation which exists between increase of elevation and the corresponding variations of temperature and moisture, these variations in their turn having an intimate bearing on the theoretic determination of atmospheric refraction. The results of Mr Glaisher's observations indicate that the [current] hypothesis ... must be abandoned ...Lee was his parents' eldest son, having one brother named Ernest and one sister. We should say a little about relations between family members to show the environment in which he was brought up. Certainly family life was happy during the first decade of Lee's life, but later it became strained. Cecilia was an artistic lady whose temperament made it difficult for her to live the highly regulated life her husband wanted. Lee, as one might expect, inherited certain characteristics from each parent: like his father he was extremely conscientious, to the degree that it made both of them difficult people to live with; like his mother he was socially retiring with a love of things artistic.
He attended St Paul's School in London from 1858, where he became somewhat of a celebrity when he was made two balloon ascents with his father in 1861. In fact his father played a major role in directing Lee's education at St Paul's to the extent that his fellow pupils were very aware of the unusual degree of his involvement. Lee showed himself a highly gifted mathematician, winning a Campden Exhibition in 1867 to study at Trinity College, Cambridge. He entered Cambridge in October 1867 and he was awarded a scholarship one year later for his outstanding performance. His mathematical researches began while he was still an undergraduate and he wrote a paper on the sine integral, cosine integral, and exponential integral, giving tables of these integrals which he had computed himself. The paper was communicated to the Royal Society by Cayley.
In the final examination of 1871 Glaisher was placed second :-
As he went up to receive his degree the undergraduates who had gathered in the gallery at the Cambridge Senate House began to sing a music hall ditty entitled 'Up in a balloon, boys'. The students, like his schoolfellows, evidently associated him with his father's exploits.Elected to a fellowship at Trinity College in 1871, he became a tutor and lecturer and taught at Cambridge all his life. In the same year in which he graduated Glaisher joined the Royal Astronomical Society and so began a long association with that Society. In 1872 he joined the London Mathematical Society. He went on to hold high office in both these Societies, being Secretary of the Royal Astronomical Society from 1877 to 1884, then President from 1886 to 1888 and again from 1901 to 1903. He was President of the London Mathematical Society 1884-1886. He served on the Council of the Royal Astronomical Society from 1874 until his death 54 years later. He also played an important role in the British Association for the Advancement of Science. He joined the Association in 1869, being appointed to the Committee on Mathematical Tables in 1872. He was Secretary of Section A, then President of the Section in 1890. His presidential address, given at Leeds on 4 September 1890, was on Mathematical and Physical Science. In this address he explained what he considered pure mathematics to be:-
By pure mathematics I do not mean the ordinary processes of algebra, differential and integral calculus etc., which every worker in the so-called mathematical sciences should have at his command. I refer to the abstract sciences which do not rest upon experiment in the ordinary sense of the term. Their fundamental principles are derived from observations so simple as to be almost axiomatic. To this class belong the theories of magnitude and position, the former, including all that relates to quantity, whether discrete or continuous, and the latter to all branches of geometry.During his time as a lecturer at Cambridge Glaisher had many interests. He was a keen cyclist, riding a 'penny-farthing' bicycle, and also a keen walker striding out at a speed few could match. He also found great pleasure in travelling enjoying frequent visits to the Continent and to the United States. Two favourite hobbies were reading and collecting pottery, although he took them so seriously that it seems somewhat inappropriate to call them hobbies. We say more below about his pottery collection but let us record here his lifelong passion for reading led to him amass of vast library which he bequeathed to Cambridge University.
Glaisher wrote over 400 articles on his main interests of astronomy, special functions, calculation of numerical tables, number theory, and the history of mathematics. His historical interests were on the early development of numerical computation, Stevin and the beginnings of the decimal system, Napier, Briggs and the beginnings of logarithms as well as the mathematical notation + and -. He applied special functions to problems in number theory, in particular representations of integers as sums of squares.
The importance of Glaisher is less in the original research he did, much more in that he brought these mathematical topics into the Cambridge syllabus so setting it up to produce the outstanding English mathematicians who were educated there shortly afterwards. Forsyth, writes in :-
The earliest years of his teaching at Cambridge were a time of transition in the mathematical ideals of the University. Cayley was almost a voice in the wilderness; Glaisher himself described Cambridge pure mathematics as generals without armies. When he had ceased teaching, Cambridge pure mathematics had marched beyond his active vision mainly under men whom, as students, he had guided at the beginning. His voice was that of a teacher, yet not in the least similar to the great Cambridge coaches, for he contributed to his science and ranged far beyond conventional examination learning. He was a personality in his day; and he left a name, high among the noted names of his generation, in two widely different fields of constructive thought and human activity.Hunt  writes that Glaisher:-
... was an extraordinary teacher who inspired others to accept positive attitudes to research. He was less concerned with the necessity of teaching pupils how to pass examinations than he was giving them a wide-ranging interest in the subject. He applied this all-embracing and open approach to every activity in which he became interested and that is one reason he was able to excel in a number of different fields. ... During lectures at the University he dealt with his subjects explicitly, if in an unorthodox manner. He spoke clearly and used blackboard illustrations freely. At the end of a lecture his gown was often covered with chalk dust.Glaisher received many honours. He was elected a Fellow of the Royal Society in 1875, served three terms on its council, received the Society's Sylvester Medal in 1913, and was vice-president in 1917-19. He received the De Morgan Medal of the London Mathematical Society in 1908. He was elected a Fellow of the Royal Society of Edinburgh, the National Academy of Sciences in the United States, and was awarded an honorary degree by Victoria University Manchester (1902) and the University of Dublin on the occasion of their tercentenary. He also served as president of some Societies with interests far removed from mathematics being president of the Cambridge Antiquarian Society and the Cambridge University Bicycle Club from 1882 to 1885. He was president of the Cambridge Philosophical Society 1882-84, and elected an honorary fellow of the Manchester Literary and Philosophical Society.
One honour, which it is almost certain he was offered, was the office of Astronomer Royal. It is believed that Glaisher was offered this post when Airy retired in 1881 but that he declined :-
Acceptance would have meant that he would have been obliged to leave his beloved Cambridge for Greenwich and lose the security he obviously felt as a resident of Trinity. It is also highly likely that he was plagued by recollections of traumatic events which took place at Greenwich during his adolescence.Now if being Astronomer Royal was one post offered to Glaisher that he turned down, one which he would dearly have loved to accept was the Sadleirian Chair. It became vacant in 1895 when Cayley died but A R Foster, one of Glaisher's pupils, was appointed rather than Glaisher himself. There is no obvious reason why he should have been passed over for the Chair. However, Hunt suggests :-
Soon after his appointment to the post of Lecturer at Trinity he began to campaign for the reform of the Cambridge Tripos Examination. This may have not impressed all members of the Establishment and in the pursuit of what he deemed to be correct he may have failed to cultivate the good offices of men who were well placed to help him in his career.We should also say a little about the important editorial work done by Glaisher. He edited both the Messenger of Mathematics and the Quarterly Journal of Mathematics. In both cases he began as one of a team of editors and ended up as the sole editor. We should note one particularly important result of his editorial work with the Messenger of Mathematics. Thomas Fiske was an American who spent time at the University of Cambridge while undertaking graduate studies. He wrote that:-
... from Dr J W L Glaisher, who made me an intimate friend, who spent many an evening with me in heart to heard talks, who took me to meetings of the London Mathematical Society and the Royal Astronomical Society, and entertained me with gossip about scores of contemporary and earlier mathematicians, I gained more in a general way than from anyone else.What had this to do with the Messenger of Mathematics? Well, after Fiske returned to the United States he went on the organise the New York Mathematical Society (which became the American Mathematical Society) and set up the Bulletin of the New York Mathematical Society based on the format of the Messenger of Mathematics that Glaisher had established.
One of Glaisher's hobbies was collecting works of art :-
... he will be remembered as one of the leading pottery collectors of his time. His attention in this direction was at first occupied by Delft ware, but from the Dutch pottery he was led to take an interest in the English wares made in emulation of it, and so in other types of English pottery of early date.Forsyth  describes the affect on his rooms at Cambridge:-
... his collections never ceased to grow, always under his earnest care. ... his collections outgrew available space, downstairs, upstairs, even in his remote bedroom. He was granted an additional set of rooms at the top of his staircase and next to the upper floor of his own set; they, too, soon were filled. He then hired a sort of warehouse, that also became filled in due course. ... the Fitzwilliam Museum ... granted him a room (also soon filled) in the new wing...As to Glaisher's character, Forsyth tells us  that:-
His smile of appreciation was delightful and infectious; when appreciation waxed into admiration, his attractive eyes would glow in his enthusiasm. Singularly fluent, he never aimed at eloquence in speech, yet dignified passages abound in his formal addresses. ... There was no shred of pomposity in his bearing, which was frank and simple.
