Educated at Harrow, where he first showed an interest in science, and at Cambridge, Talbot was an outstanding scholar and a formidable mathematician. He published over fifty scientific papers and took out twelve English patents. His interests outside the field of science were also wide and included Assyriology, etymology and the classics. He was briefly a Member of Parliament, but did not pursue a parliamentary career.

Talbot's invention of photography arose out of his frustrating attempts to produce acceptable pencil sketches using popular artist's aids, the camera discura and camera lucida. From his experiments with the former he conceived the idea of placing on the screen a paper coated with silver salts so that the image would be captured chemically. During the spring of 1834 he made outline images of subjects such as leaves and flowers by placing them on sheets of sensitized paper and exposing them to sunlight. No camera was involved and the first images produced using an optical system were made with a solar microscope. It was only when he had devised a more sensitive paper that Talbot was able to make camera pictures; the earliest surviving camera negative dates from August 1835. From the beginning, Talbot noticed that the lights and shades of his images were reversed. During 1834 or 1835 he discovered that by placing this reversed image on another sheet of sensitized paper and again exposing it to sunlight, a picture was produced with lights and shades in the correct disposition. Talbot had discovered the basis of modern photography, the photographic negative, from which could be produced an unlimited number of positives. He did little further work until the announcement of Daguerre's process in 1839 prompted him to publish an account of his negative-positive process. Aware that his photogenic drawing process had many imperfections, Talbot plunged into further experiments and in September 1840, using a mixture incorporating a solution of gallic acid, discovered an invisible latent image that could be made visible by development. This improved calotype process dramatically shortened exposure times and allowed Talbot to take portraits. In 1841 he patented the process, an exercise that was later to cause controversy, and between 1844 and 1846 produced The Pencil of Nature, the world's first commercial photographically illustrated book.

Concerned that some of his photographs were prone to fading, Talbot later began experiments to combine photography with printing and engraving. Using bichromated gelatine, he devised the first practicable method of photo engraving, which was patented as Photoglyphic engraving in October 1852. He later went on to use screens of gauze, muslin and finely powdered gum to break up the image into lines and dots, thus anticipating modern photomechanical processes.

Talbot was described by contemporaries as the "Father of Photography" primarily in recognition of his discovery of the negative-positive process, but he also produced the first photomicrographs, took the first high-speed photographs with the aid of a spark from a Leyden jar, and is credited with proposing infra-red photography. He was a shy man and his misguided attempts to enforce his calotype patent made him many enemies. It was perhaps for this reason that he never received the formal recognition from the British nation that his family felt he deserved.

Sent to stay with relatives at the age of 6 because of the illness of his father, when the latter died in 1811 Henry was apprenticed to a silversmith and then turned to the stage. Whilst he was ill himself, a book on science fired his interest and he began studying at Albany Academy, working as a tutor to finance his studies. Initially intending to pursue medicine, he then spent some time as a surveyor before becoming Professor of Mathematics and Natural Philosophy at Albany Academy in 1826. There he became interested in the improvement of electromagnets and discovered that the use of an increased number of turns of wire round the core greatly increased their power; by 1831 he was able to supply to Yale a magnet capable of lifting almost a ton weight. During this time he also discovered the principles of magnetic induction and self-inductance. In the same year he made, but did not patent, a cable telegraph system capable of working over a distance of 1 mile (1.6 km). It was at this time, too, that he found that adiabatic expansion of gases led to their sudden cooling, thus paving the way for the development of refrigerators. For this he was recommended for, but never received, the Copley Medal of the Royal Society. Five years later he became Professor of Natural Philosophy at New Jersey College (later Princeton University), where he deduced the laws governing the operation of transformers and observed that changes in magnetic flux induced electric currents in conductors. Later he also observed that spark discharges caused electrical effects at a distance. He therefore came close to the discovery of radio waves. In 1836 he was granted a year's leave of absence and travelled to Europe, where he was able to meet Michael Faraday. It was with his help that in 1844 Samuel Morse set up the first patented electric telegraph, but, sadly, the latter seems to have reaped all the credit and financial rewards. In 1846 he became the first secretary of the Washington Smithsonian Institute and did much to develop government support for scientific research. As a result of his efforts some 500 telegraph stations across the country were equipped with meteorological equipment to supply weather information by telegraph to a central location, a facility that eventually became the US National Weather Bureau. From 1852 he was a member of the Lighthouse Board, contributing to improvements in lighting and sound warning systems and becoming its chairman in 1871. During the Civil War he was a technical advisor to President Lincoln. He was a founder of the National Academy of Science and served as its President for eleven years.

Mitchell's early education commenced at Ledingham's Academy, Correction Wynd, Aberdeen, and from there he became a premium apprentice at the Footdee Engineering Works of Wm Simpson \& Co. Despite being employed for around twelve hours each day, Mitchell matriculated at Marischal College (now merged with King's College to form the University of Aberdeen). He did not graduate, although in 1840 he won the chemistry prize. On the completion of his apprenticeship, like Andrew Leslie (founder of Hawthorn Leslie) and other young Aberdonians he moved to Tyneside, where most of his working life was spent. From 1842 until 1844 he worked as a draughtsman for his friend Coutts, who had a shipyard at Low Walker, before moving on to the drawing offices of Maudslay Sons and Field of London, then one of the leading shipbuilding and engineering establishments in the UK. While in London he studied languages, acquiring a skill that was to stand him in good stead in later years. In 1852 he returned to the North East and set up his own iron-ship building yard at Low Walker near Newcastle. Two years later he married Anne Swan, the sister of the two young men who were to found the company now known as Swan Hunter Ltd. The Mitchell yard grew in size and reputation and by the 1850s he was building for the Russian Navy and Merchant Marine as well as advising the Russians on their shipyards in St Petersburg. In 1867 the first informal business arrangement was concluded with Armstrongs for the supply of armaments for ships; this led to increased co-operation and ultimately in 1882 to the merger of the two shipyards as Sir W.G.Armstrong Mitchell \& Co. At the time of the merger, Mitchell had launched 450 ships in twenty-nine years. In 1886 the new company built the SS Gluckauf, the world's first bulk oil tanker. After ill health in 1865 Mitchell reduced his workload and lived for a while in Surbiton, London, but returned to Tyneside to a new house at Jesmond. In his later years he was a generous benefactor to many good causes in Tyneside and Aberdeen, to the Church and to the University of Aberdeen.

Page graduated from Harvard in 1832 and subsequently attended Boston Medical School. He began to practise in Salem and also engaged in experimental research in electricity, discovering the improvement effected by substituting bundles of iron wire for solid bars in induction coils. He also created a device which he termed a Dynamic Multiplier, the prototype of the auto-transformer. Following a period in medical practice in Virginia, in 1841 he became one of the first two principal examiners in the United States Patent Office. He also held the Chair of Chemistry and Pharmacy at Columbian College, later George Washington University, between 1844 and 1849.

A prolific inventor, Page completed several large electric motors in which reciprocating action was converted to rotary motion, and invested an extravagant sum of public money in a foredoomed effort to develop a 10-ton electric locomotive powered by primary batteries. This was unsuccessfully demonstrated in April 1851 on the Washington-Baltimore railway and seriously damaged his reputation. Page approached Thomas Davenport with an offer of partnership, but Davenport refused.

After leaving the Patent Office in 1852 he became a patentee himself and advocated the reform of the patent procedures. Page returned to the Patent Office in 1861, and later persuaded Congress to pass a special Act permitting him to patent the induction coil. This was the cause, after his death, of protracted and widely publicized litigation.

The son of a farmer, he had worked in gardens since boyhood and at the age of 21 was employed as Undergardener at the Horticultural Society Gardens in Chiswick, from where he went on to become Head Gardener for the Duke of Devonshire at Chatsworth. It was there that he developed his methods of glasshouse construction, culminating in the Great Conservatory of 1836–40, an immense structure some 277 ft (84.4 m) long, 123 ft (37.5 m) wide and 67 ft (20.4 m) high. Its framework was of iron and its roof of glass, with wood to contain the glass panels; it is now demolished. Paxton went on to landscape garden design, fountain and waterway engineering, the laying out of the model village of Edensor, and to play a part in railway and country house projects.

The structure that made Paxton a household name was erected in Hyde Park, London, to house the Great Exhibition of 1851 and was aptly dubbed, by Punch, the Crystal Palace. The idea of holding an international exhibition for industry had been mooted in 1849 and was backed by Prince Albert and Henry Cole. The money for this was to be raised by public subscription and 245 designs were entered into a competition held in 1850; however, most of the concepts, received from many notable architects and engineers, were very costly and unsuitable, and none were accepted. That same year, Paxton published his scheme in the Illustrated London News and it was approved after it received over-whelming public support.

Paxton's Crystal Palace, designed and erected in association with the engineers Fox and Henderson, was a prefabricated glasshouse of vast dimensions: it was 1,848 ft (563.3 m) long, 408 ft (124.4 m) wide and over 100 ft (30.5 m) high. It contained 3,300 iron columns, 2,150 girders. 24 miles (39 km) of guttering, 600,000 ft3 (17,000 m³) of timber and 900,000 ft2 (84,000 m) of sheet glass made by Chance Bros, of Birmingham. One of the chief reasons why it was accepted by the Royal Commission Committee was that it fulfilled the competition proviso that it should be capable of being erected quickly and subsequently dismantled and re-erected elsewhere. The Crystal Palace was to be erected at a cost of £79,800, much less than the other designs. Building began on 30 July 1850, with a labour force of some 2,000, and was completed on 31 March 1851. It was a landmark in construction at the time, for its size, speed of construction and its non-eclectic design, and, most of all, as the first great prefabricated building: parts were standardized and made in quantity, and were assembled on site. The exhibition was opened by Queen Victoria on 1 May 1851 and had received six million visitors when it closed on 11 October. The building was dismantled in 1852 and reassembled, with variations in design, at Sydenham in south London, where it remained until its spectacular conflagration in 1936.
