The Illuminating Engineering Society was founded in 1908 following an informal meeting arranged by Leon Gaster, editor of The Illuminating Engineer, which had been established the year before. The Society continued until 1977 when it merged with the Institution of Heating and Ventilating Engineers to form The Chartered Institution of Building Services. (It was a few years later that Engineers was added to the title).
The centenary of the founding of IES has now passed, but the intention is still to provide background information on its Presidents. Listing all their names on this website is to encourage contributions from as wide an audience as possible.
|The IES had a total of 55 Presidents. Apart from the early period, the majority served for a term of one year. J W T Walsh was the only member to be elected twice, in 1929 and again in 1947.|

Alexander Pelham Trotter (1857-1947) During his long and distinguished career he played many parts. He was apprenticed to Easton & Anderson, took out patents for prismatic glassware, and became a partner in Goolden and Trotter, dynamo manufacturers. This was followed by becoming editor of The Electrician for six years, service as Government electrical engineer for the Cape of Good Hope, then Electrical Advisor to the Board of Trade. After retirement he joined the Consulting Engineers Handcock and Dykes.
He had a logical mind and was keen to try new inventions. He experimented at Trinity College, Cambridge, with the new Graham Bell receivers in 1877 (the actual year of the first published account) and obtained clear though faint speech across the quadrangle. Later he made his own wireless receiver at a time when many younger men lacked the confidence to attempt such novel work.
He was a Member of the Institution of Civil Engineers, the Institution of Electrical Engineers (delivered the Faraday lecture in 1926), Fellow of the Physical Society and other bodies. He was one of the founder members of the Illuminating Engineering Society.
Two of his books are considered as classics; “Illumination: Its Distribution and Measurement”(1911) and “The Elements of Illuminating Engineering”(1929).
It was his paper entitled ‘The Distribution and Measurement of Illumination” read before the ICE in 1892 that became the basis for modern illuminating engineering. This paper was awarded the Telford Medal and premium, and described a portable illumination photometer and its application to street lighting. At that time there were no internationally agreed lighting units it was necessary to compare the French “carcel-metre” with the “candle-foot” based upon the English Parliamentary candle.

Alexander Trotter advised on war-time street
lighting, making observations from a balloon
for the purpose and was made chairman of the
IES Committee, which conducted tests of
parachute flares, etc., for the Department of
Trench Warfare. In 1915 he conducted some
outdoor tests with MacGregor-Morris, Edgcumbe,
Clinton, Blok and Dow in an open space behind
the School of Mines in
Exhibition Road South
Kensington London. Although they had been
given permission by a police officer they
later learned that Woolwich
Arsenal, seeing the illumination of clouds
over South Kensington, thought an enemy raid
had started. As a consequence further tests
were moved out to Tooting Common and
Stonebridge Park. After the war he was

He spoke French fluently and he and his wife often went to visit M. Blondel in Paris. They had much in common as both had independently developed the dioptric method of distributing light from a source for street lighting.
After his retirement to Greystones, Teffont, near Salisbury Wiltshire, he indulged in his many hobbies, making simple scientific toys – mainly in wood – in his workshop. He studied the art of printing and had his own printing press, which he used to print and bind poetry written by his wife.
President 1928 -1929
Sir Clifford Copland Paterson (1879 - 1948) was born in Stoke Newington, son of a tanner and leather merchant. He was educated at Mill Hill School and then trained in general and electrical engineering at Finsbury Technical College and Faraday House. In 1901 he was selected by Richard Glazebrook to join the newly created NPL, where he became responsible for the Electrotechnical and Photometric Departments.
He was awarded an OBE in 1916 for his work on the Paterson-Walsh aircraft height finder, and in the same year was approached by Osram Lamp works in Hammersmith to set up a research department for them (before the war Osram had depended upon German technology), but he was not free to accept such a post during the war. Five days later after the Armistice had been declared Hugo (later Lord) Hirst asked him to become a founder director of the GEC research laboratories. Originaly housed at Hammersmith, 71 staff moved into a purpose built facility in Wembley in 1922. Work on filament lamps developed into thermionic valves. Starting with a small team of five or six, during WWII the staff grew to more than a thousand and their work on searchlights, camouflage, radio and radar was to play a key part in the war effort, rewarded by his knighthood in 1946. This period of his life is recorded in "A Scientist's War - The War Diary of Sir Clifford Paterson 1939 -1945 edited by Clayton and Algar.
He was President of the IES during 1928 -1929 and the IEE in 1930 -1931, served on Committee's of Department of Scientific and Industrial Research, notable its Lighting of Building report in 1944 which brought the Architectural and Lighting professions closer together.
He was appointed to the board of GEC in 1941 and and received his knighthood in 1946.
He was awarded Fellowship of The Royal Society, received an Honary Doctorate of Science from Birmingham University. The Gold Medal of IES of North America was presented to his wife on 23rd July only 3 days before his death.
The International Commission set up in 1900 and Paterson attended as NPL representative in 1907. This became in the International Commission on Illumination in 1913 and Paterson served as Hon Secretary of from its formation, and was instrumental in its revival after the war with the first technical session in Paris in 1921.
Paterson remained Hon Secretary of ICI until his death with only one break when he was its President during 1928 - 31. This period as President culminated with the International Illumination congress in UK with 140 delegates from overseas. It formed the first large scale demonstations of the floodlighting of buildings.
His work during the second world war is documented in "A Scientist's War - the War Diary of Sir Clifford Paterson" by Clayton and Alger (ISBN 0 86341 218 1).
Apart from his scientific attainments he is remembered for his high principles and human personality to inspire team spirit whilst allowing his staff freedom to work.
Born in Bristol he was educated at the University College Bristol and completed at St Bartholomew’s Hospital London. He took a degree in physiology and qualified in medicine. He became ophthalmic surgeon to University College London and the Hospital for Sick Children Great Ormond Street, London. But medical practice was not his first love. He lived for research and clinical ophthalmology was insufficient he needed to investigate the optics together with the perceptual and psychological aspects of vision and sensory perception in their widest sense.

Throughout the whole of his career he was associated with the Gas Light and Coke Company of which he became Controller of Gas Sales. For many years he was Executive chairman of British Commercial Gas Association. It was largely through his influence that the service side of the gas industry was developed and its social aspects were so assiduously cultivated. He also served on many government committees and was identified with numerous social and charitable movements.
He was a founder member of IES in which he took a keen interest serving on the council and committees before becoming president. He served on the National Illumination Committee and was involved with the organisation of International Illumination /Conference in England in 1931.

JOHN COLLINS 1918-1990
Started his lighting career at GEC Hirst Research Centre. During the second world war he served in the Admiralty working on searchlights and signal visibility at HMS Vernon. Later he joined the Royal Naval Scientific Service and worked under W D Chesterman and J Y Cousteau on underwater photography.
In 1949 he joined Building Research Station to work with R G Hopkinson on daylight and artificial light in buildings, including studies on flicker, visual fatigue and hospital lighting.
He was made a Fellow of the Society in 1954 and was vice president from 1971 to 1973. He chaired the Papers Committee in 1969-70, and served on the IES Awards Committee and Technical Committee including the drafting of the 1973 Code, and again in 1975. Between these last two posts he was chairman of the panel considering revision of the IES Glare System.
