Outstanding Teacher

Arthur Mannering Tyndall was a man who played a leading part in the establishment of research and teaching in physics in one of the newer universities of this country. His whole career was spent in the University of Bristol, where he was Lecturer, Professor and for a while Acting ViceChancellor, and his part in guiding the development of Bristol from a small university college to a great university was clear to all who knew him. He presided over the building and development of the H. H. Wills Physical Laboratory, and his leadership brought it from its small beginnings to its subsequent achievements. His own work, for which he was elected to the Fellowship of the Royal Society, was on the mobility of gaseous ions. Arthur Tyndall was born in Bristol on 18 September 1881. He was educated at a private school in Bristol where no science was taught, except a smattering of chemistry in the last two terms. Nonetheless he entered University College, obtaining the only scholarship offered annually by the City of Bristol for study in that college and intending to make his career in chemistry. However, when brought into contact with Professor Arthur Chattock, an outstanding teacher on the subject, he decided to switch to physics; he always expressed the warmest gratitude for the inspiration that he had received from him. He graduated with second class honours in the external London examination in 1903. In that year he was appointed Assistant Lecturer, was promoted to Lecturer in 1907, and became Lecturer in the University when the University College became a university in 1909. During this time he served under Professor A. P. Chattock, but Chattock retired in 1910 at the age of 50 and Tyndall became acting head of the department. Then, with the outbreak of war, he left the University to run an army radiological department in Hampshire.

Happy Family

From his appointment as a Scientific Officer at the Radio Division of the National Physical Laboratory in 1938, which marked the start of his active collaboration with Sir Edward Appleton, to his death in 1996, Granville Beynon's chosen field of scientific endeavour was the study of the ionosphere, the atmosphere at heights where the concentration of free electrons is sufficient to influence the propagation of radio waves. Through his establishment of research groups at Swansea and Aberystwyth Colleges of the University of Wales, and his tenure of senior offices in appropriate national and international committees, he had a major influence in this area of science. His involvement in university education included a period as Vice–Principal at Aberystwyth, but his interest in education extended beyond the university sector and this was marked by his service as Chairman of the Schools Council Committee for Wales. For his services to science and education he received several honours at both national and international levels. In spite of the many demands on his time, he enjoyed a very happy family life in which music played a central part.

Photo Ionization

Characteristically active to the end, Robert Ditchburn collapsed as he arrived at King’s College London (KQC), for a meeting of the British Pugwash Group on 8 April, and died shortly afterwards. His interests and influence extended widely beyond his own fields of research in physics, diverse though these were, and he wrote of him self: ‘if I could have had equal health, wealth and opportunity for scientific work I would have liked to live in an earlier period when it was possible to range over wide areas of science.... My work has been less specialized than that of most of my contemporaries but still more specialized than I would have liked.’ His main fields of research were, in fact, the following: (i) the photo-ionization of gases and vapours, (ii) other absorption processes relevant to the upper atmosphere, (iii) the optical properties of solids, especially diamonds, and (iv) the effect of eye movements on visual perception. Included in this list is what he will be especially remembered for, the development and application of methods for stabilizing images on the retina. But perhaps his main contribution to the advancement of science— this was his own judgement— was his work in building the Department of Physics in the University of Reading: the J. J. Thomson Physical Laboratory. He was proud to have been among the last research students of J. J. in the Cavendish, and he succeeded in having the new building in Whiteknights Park named after him. He himself had been appointed professor and head of the department in 1946, succeeding J. A. Crowther. He retired from the chair and headship in 1968. He was succeeded in the chair by the author of the present memoir, and in the headship by E. W. J. Mitchell, at that time Professor of the Physical Properties of Materials at Reading, now C.B.E., F.R.S., and Chairm an of SERC. Robert Ditchburn continued his work on eye movements after his retirement, working in the Department of Engineering at Reading (which, in 1968, was part of the Department of Applied Physical Sciences), and carrying forward a long collaboration with J. A. Foley- Fisher. His second book Eye movements and visual perception , was published during this period. He took advantage of his greater freedom to pursue his wider interests: he continued his work as a consultant to the diamond industry, and he devoted much time to the Pugwash Movement — this he considered to be his most worthwhile activity after his retirement. It was fitting that his last hours should have been spent in going about its business.

Scientific Achievements

When Professor R. W. Wood died on 11 August 1955 he was to the younger generation of physicists a colourful legend, a representative of the past. He was, however, by no means forgotten, as a lesser man might have been at the age of 87. Many stories were still circulating about him. When I recently paid a visit to the University of Wisconsin which Wood had left in 1901, his exploits were being discussed there as if they had just happened, instead of more than half a century before. His solid scientific achievements are now a matter of record. His active mind refused to accept retirement and he visited his old room in the Physical Laboratory at The Johns Hopkins University regularly until nearly the end, even though the infirmities of old age had gradually made themselves felt. He never gave up his curiosity about things and was still actively engaged in the revision of his book on Physical optics . Death came to him peacefully: he passed away during his sleep without any severe illness. Wood’s active period of scientific productivity coincided with the rise of atomic physics and he made important contributions toward the increasing knowledge of the structure of the atom, chiefly through his experimental researches in physical optics. He was, however, far from one-sided and penetrated into many fields. He went wherever his insatiable curiosity led him, whether this was into different branches of physics or into all sorts of other activities such as engineering, art, crime detection, spiritualism, psychology, archaeology and many others

The experiments on the thermal conductivity of water, of which an account is given in the following paper, were undertaken at the wish of Sir William Thomson, and by a method devised by him some years ago. They have been carried out in several successive Winter Sessions in the Physical Laboratory of the University of Glasgow, with the assistance of students and experimental scholars, among whom I must mention specially Mr. J. Reid, Jun., and Mr. M. T. Brown. Description of apparatus .—Figs. 1 and 2 show the arrangement of apparatus for experiments on the thermal conductivity of a liquid. In each case I have a vessel or tank so large that the heat lost at the sides does not affect sensibly the condition of the central portion of the liquid, either directly, or by convection currents set up close to the sides. The water or other liquid to be experimented on is contained in this vessel and is heated from above.

In the Proceedings of the Royal Society of Edinburgh for 1874–75 there is a short paper on the “Electrical Resistance of Iron at a High Temperature.” It is the record of certain experiments made by three of us, then students in the Physical Laboratory of the University of Edinburgh; and its conclusion is that there is a peculiarity in the behaviour of iron as an electric conductor at the temperature of a dull red heat. At this temperature other physical peculiarities are known to exist, particularly as regards its thermal expansion, its thermal capacity, and its specific heat for electricity. The discovery of these striking properties we owe respectively to Dr Gore, Professor Barrett, and Professor Tait.

John Lennard-Jones was born on 27 October 1894 in Leigh, Lancashire and was educated at Leigh Grammar School, where he specialized in classics. In 1912 he entered Manchester University, changed his subject to mathematics in which he took an honours degree and then an M.Sc. under Professor Lamb, carrying out some research on the theory of sound. In 1915 he joined the Royal Flying Corps, obtained his Wings in 1917 and saw service in France; he also took part in some investigations on aerodynamics with Messrs Boulton and Paul and at the National Physical Laboratory. In 1919 he returned to the University of Manchester as lecturer in mathematics, took the degree of D.Sc. of that university and continued to work on vibrations in gases, becoming more and more interested in the gas-kinetic aspects of the subject as his paper of 1922 in the Philosophical Transactions of the Royal Society shows. In 1922, on the advice of Professor Sydney Chapman, he applied for and was elected to a Senior 1851 Exhibition to enable him to work in Cambridge, where he became a research student at Trinity College and was awarded the degree of Ph.D. in 1924. At Cambridge under the influence of R. H. Fowler he became more and more interested in the forces between atoms and molecules and in the possibility of deducing them from the behaviour of gases.

Alternating Magnetic Fields

Thomas Lydwell Eckersley was born on 27 December 1886 in London. His mother was a daughter of Thomas Henry Huxley who was at one time President of the Royal Society. From the age of 2 1/2 to 6 Eckersley lived in Mexico where his father, who was a civil engineer, was engaged in building a railway. In his early life Eckersley was interested in engineering and in scientific devices and he had a desire to emulate his father and to build bridges. At the age of 11 he went to Bedales School where he came under the influence of an able teacher of mathematics who laid the foundations of his life-long interest in the subject. He left school at the early age of 15 and went to University College London, to read engineering, but he found he was not really as interested in the practical aspects of the work as he had at one time supposed, and he achieved only a Second Class degree. On leaving the University he went to the National Physical Laboratory where he found himself working under Albert Campbell on the behaviour of iron under the influence of alternating magnetic fields. Through this work he became interested in magnetic detectors for radio waves, and he did a good deal of experimenting with radio apparatus at his own house. His first paper was published, jointly with Campbell, on the effect of Pupin loading coils on waves travelling along transmission lines.
