Ferguson's father was a small farmer who expected his son to help on the farm from an early age. As a result he received little formal education, and on leaving school joined his brother in a backstreet workshop in Belfast repairing motor bikes. By the age of 19 he had built his own bike and began hill-climbing competitions and racing. His successes in these ventures gained useful publicity for the workshop. In 1907 he built his own car and entered it into competitions, and in 1909 became the first person in Britain to build and fly a machine that was heavier than air.

On the outbreak of the First World War he was appointed by the Irish Department of Agriculture to supervise the operation and maintenance of all farm tractors. His experiences convinced him that even the Ford tractor and the implements available for it were inadequate for the task, and he began to experiment with his own plough designs. The formation of the Ferguson-Sherman Corporation resulted in the production of thousands of the ploughs he had designed for the Ford tractor, but in 1928 Ford discontinued production of tractors, and Ferguson returned to Ireland. He immediately began to design his own tractor. Six years of development led to the building of a prototype that weighed only 16 cwt (813kg). In 1936 David Brown of Huddersfield, Yorkshire, began production of these tractors for Ferguson, but the partnership was not wholly successful and was dissolved after three years. In 1939 Ferguson and Ford reached their famous "Handshake agreement", in which no formal contract was signed, and the mass production of the Ford Ferguson system tractors began that year. During the next nine years 300,000 tractors and a million implements were produced under this agreement. However, on the death of Henry Ford the company began production, under his son, of their own tractor. Ferguson returned to the UK and negotiated a deal with the Standard Motor Company of Coventry for the production of his tractor. At the same time he took legal action against Ford, which resulted in that company being forced to stop production and to pay damages amounting to US$9.5 million.

Aware that his equipment would only operate when set up properly, Ferguson established a training school at Stoneleigh in Warwickshire which was to be a model for other manufacturers. In 1953, by amicable agreement, Ferguson amalgamated with the Massey Harris Company to form Massey Ferguson, and in so doing added harvesting machinery to the range of equipment produced. A year later he disposed of his shares in the new company and turned his attention again to the motor car. Although a number of experimental cars were produced, there were no long-lasting developments from this venture other than a four-wheel-drive system based on hydraulics; this was used by a number of manufacturers on occasional models. Ferguson's death heralded the end of these developments.

Froude was educated at a preparatory school at Buckfastleigh, and then at Westminster School, London, before entering Oriel College, Oxford, to read mathematics and classics. Between 1836 and 1838 he served as a pupil civil engineer, and then he joined the staff of Isambard Kingdom Brunel on various railway engineering projects in southern England, including the South Devon Atmospheric Railway. He retired from professional work in 1846 and lived with his invalid father at Dartington Parsonage. The next twenty years, while apparently unproductive, were important to Froude as he concentrated his mind on difficult mathematical and scientific problems. Froude married in 1839 and had five children, one of whom, Robert Edmund Froude (1846–1924), was to succeed him in later years in his research work for the Admiralty. Following the death of his father, Froude moved to Paignton, and there commenced his studies on the resistance of solid bodies moving through fluids. Initially these were with hulls towed through a house roof storage tank by wires taken over a pulley and attached to falling weights, but the work became more sophisticated and was conducted on ponds and the open water of a creek near Dartmouth. Froude published work on the rolling of ships in the second volume of the Transactions of the then new Institution of Naval Architects and through this became acquainted with Sir Edward Reed. This led in 1870 to the Admiralty's offer of £2,000 towards the cost of an experimental tank for ship models at Torquay. The tank was completed in 1872 and tests were carried out on the model of HMS Greyhound following full-scale towing trials which had commenced on the actual ship the previous year. From this Froude enunciated his Law of Comparisons, which defines the rules concerning the relationship of the power required to move geometrically similar floating bodies across fluids. It enabled naval architects to predict, from a study of a much less expensive and smaller model, the resistance to motion and the power required to move a full-size ship. The work in the tank led Froude to design a model-cutting machine, dynamometers and machinery for the accurate ruling of graph paper. Froude's work, and later that of his son, was prodigious and covered many fields of ship design, including powering, propulsion, rolling, steering and stability. In only six years he had stamped his academic authority on the new science of hydrodynamics, served on many national committees and corresponded with fellow researchers throughout the world. His health suffered and he sailed for South Africa to recuperate, but he contracted dysentery and died at Simonstown. He will be remembered for all time as one of the greatest "fathers" of naval architecture.

George B.Grant was descended from families who came from Britain in the seventeenth century and was educated at the Bridgton (Maine) Academy, the Chandler Scientific School of Dartmouth College and the Lawrence Scientific School of Harvard College, where he graduated with the degree of BS in 1873. As an undergraduate he became interested in calculating machines, and his paper "On a new difference engine" was published in the American Journal of Science in August 1871. He also took out his first patents relating to calculating machines in 1872 and 1873. A machine of his design known as "Grant's Difference Engine" was exhibited at the Centennial Exposition in Philadelphia in 1876. Similar machines were also manufactured for sale; being sturdy and reliable, they did much to break down the prejudice against the use of calculating machines in business. Grant's work on calculating machines led to a requirement for accurate gears, so he established a machine shop for gear cutting at Charlestown, Massachusetts. He later moved the business to Boston and incorporated it under the name of Grant's Gear Works Inc., and continued to control it until his death. He also established two other gear-cutting shops, the Philadelphia Gear Works Inc., which he disposed of in 1911, and the Cleveland Gear Works Inc., which he also disposed of after a few years. Grant's commercial success was in connection with gear cutting and in this field he obtained several patents and contributed articles to the American Machinist. However, he continued to take an interest in calculating machines and in his later years carried out experimental work on their development.

Isaac Holden's father, who had the same name, had been a farmer and lead miner at Alston in Cumbria before moving to work in a coal-mine near Glasgow. After a short period at Kilbarchan grammar school, the younger Isaac was engaged first as a drawboy to two weavers and then, after the family had moved to Johnstone, Scotland, worked in a cotton-spinning mill while attending night school to improve his education. He was able to learn Latin and bookkeeping, but when he was about 15 he was apprenticed to an uncle as a shawl-weaver. This proved to be too much for his strength so he returned to scholastic studies and became Assistant to an able teacher, John Kennedy, who lectured on physics, chemistry and history, which he also taught to his colleague. The elder Isaac died in 1826 and the younger had to provide for his mother and younger brother, but in 1828, at the age of 21, he moved to a teaching post in Leeds. He filled similar positions in Huddersfield and Reading, where in October 1829 he invented and demonstrated the lucifer match but did not seek to exploit it. In 1830 he returned because of ill health to his mother in Scotland, where he began to teach again. However, he was recommended as a bookkeeper to William Townend, member of the firm of Townend Brothers, Cullingworth, near Bingley, Yorkshire. Holden moved there in November 1830 and was soon involved in running the mill, eventually becoming a partner.

In 1833 Holden urged Messrs Townend to introduce seven wool-combing machines of Collier's designs, but they were found to be very imperfect and brought only trouble and loss. In 1836 Holden began experimenting on the machines until they showed reasonable success. He decided to concentrate entirely on developing the combing machine and in 1846 moved to Bradford to form an alliance with Samuel Lister. A joint patent in 1847 covered improvements to the Collier combing machine. The "square motion" imitated the action of the hand-comber more closely and was patented in 1856. Five more patents followed in 1857 and others from 1858 to 1862. Holden recommended that the machines should be introduced into France, where they would be more valuable for the merino trade. This venture was begun in 1848 in the joint partnership of Lister \& Holden, with equal shares of profits. Holden established a mill at Saint-Denis, first with Donisthorpe machines and then with his own "square motion" type. Other mills were founded at Rheims and at Croix, near Roubaix. In 1858 Lister decided to retire from the French concerns and sold his share to Holden. Soon after this, Holden decided to remodel all their machinery for washing and carding the gill machines as well as perfecting the square comb. Four years of excessive application followed, during which time £20,000 was spent in experiments in a small mill at Bradford. The result fully justified the expenditure and the Alston Works was built in Bradford.

Holden was a Liberal and from 1865 to 1868 he represented Knaresborough in Parliament. Later he became the Member of Parliament for the Northern Division of the Riding, Yorkshire, and then for the town of Keighley after the constituencies had been altered. He was liberal in his support of religious, charitable and political objectives. His house at Oakworth, near Keighley, must have been one of the earliest to have been lit by electricity.

Jenney's Home Insurance Building in Chicago was completed in 1885 but demolished in 1931. It was the first building to rise above ten to twelve storeys and was possible because it did not require immensely thick walls on the lower storeys to carry the weight above. Using square-sectioned cast-iron wall piers, hollow cylindrical cast-iron columns on the interior and, across these, steel and cast-iron beams and girders, Jenney produced a load-bearing metal framework independent of the curtain walling. Beams and girders were united by ties as well as being bolted to the vertical members, so providing a strong framework to take the building load. Jenney went on to build in Chicago the Second Leiter Building (1889–91) and, in 1891, the Manhattan Building. He played a considerable part in the planning of the 1893 Chicago World's Fair. Jenney is accepted as having been the founder of the Chicago school of architecture, and he trained many of the later noted architects and builders of the city, such as William Holabird, Martin Roche and Louis Sullivan.

Within the long tradition of celebrated teachers at the Mining Academy in Freiberg, Kegel can be considered as probably the last professor teaching the science of mining who was able to cover all the different disciplines. As was the case with a number of his predecessors, he was able to combine theoretical research work with the teaching of students and to support his theories with the practical experience of industry. He has apprenticed at the Mansfeld copper mines, went to the School of Mines at Eisleben (1896–8), worked as an engineer with various mining companies and thereafter became a scholar of the Berlin Mining Academy (1901–4). For twelve years he taught at the Bochum School of Mining until, in 1918, he was appointed Professor of Mining at Freiberg. There, one year later, as a new approach, he introduced lectures on brown-coal mining and mineral economics. He remained Professor at Freiberg until his first retirement in 1941, although he was active again between 1945 and 1951.

In 1924 Kegel took over a department at the State Research Institute for Brown Coal in Freiberg which he extended into the Institute for Briquetting. In this field his main achievement lies in the initially questioned theory that producing briquettes from lignite is a molecular process rather than the result of bituminous factors. This perception, among others, led Rammler to produce coke from lignite in 1951. Kegel's merits result from having established all the aspects of mining and using lignite as an independent subdiscipline of mining science, based on substantial theories and an innovative understanding of applied technologies.
