Several members of Champion's Quaker family were actively engaged as merchants in Bristol during the late seventeenth and the eighteenth centuries. Port records show Nehemiah in receipt of Cornish copper ore at Bristol's Crews Hole smelting works by 1706, in association with the newly formed brassworks of the city. He later became a leading partner, managing the company some time after Abraham Darby left the Bristol works to pursue his interest at Coalbrookdale. Champion, probably in company with his father, became the largest customer for Darby's Coalbrookdale products and also acted as Agent, at least briefly, for Thomas Newcomen.

A patent in 1723 related to two separate innovations introduced by the brass company.

The first improved the output of brass by granulating the copper constituent and increasing its surface area. A greater proportion of zinc vapour could permeate the granules compared with the previous practice, resulting in the technique being adopted generally in the cementation process used at the time. The latter part of the same patent introduced a new type of coal-fired furnace which facilitated annealing in bulk so replacing the individual processing of pieces. The principle of batch annealing was generally adopted, although the type of furnace was later improved. A further patent, in 1739, in the name of Nehemiah, concerned overshot water-wheels possibly intended for use in conjunction with the Newcomen atmospheric pumping engine employed for recycling water by his son William.

Champion's two sons, John and William, and their two sons, both named John, were all concerned with production of non-ferrous metals and responsible for patented innovations. Nehemiah, shortly before his death, is believed to have partnered William at the Warmley works to exploit his son's new patent for producing metallic zinc.

Nash's name is synonymous with the great scheme carried out for his patron, the Prince Regent, in the early nineteenth century: the development of Marylebone Park from 1811 constituted a "garden city" for the wealthy in the centre of London. Although only a part of Nash's great scheme was actually achieved, an immense amount was carried out, comprising the Regent's Park and its surrounding terraces, the Regent's Street, including All Souls' Church, and the Regent's Palace in the Mall. Not least was Nash's exotic Royal Pavilion at Brighton.

From the early years of the nineteenth century, Nash and a number of other architects took advantage of the use of structural materials developed as a result of the Industrial Revolution; these included wrought and cast iron and various cements. Nash utilized iron widely in the Regent Street Quadrant, Carlton House Terrace and at the Brighton Pavilion. In the first two of these his iron columns were masonry clad, but at Brighton he unashamedly constructed iron column supports, as in the Royal Kitchen, and his ground floor to first floor cast-iron staircase, in which he took advantage of the malleability of the material to create a "Chinese" bamboo design, was particularly notable. The great eighteenth-century terrace architecture of Bath and much of the later work in London was constructed in stone, but as nineteenth-century needs demanded that more buildings needed to be erected at lower cost and greater speed, brick was used more widely for construction; this was rendered with a cement that could be painted to imitate stone. Nash, in particular, employed this method at Regent's Park and used a stucco made from sand, brickdust, powdered limestone and lead oxide that was suited for exterior work.

The son of a mining officer, Oeynhausen started his career in the Prussian administration of the mining industry in 1816, immediately after he had finished his studies in natural sciences and mathematics at the University of Göttingen. From 1847 until his retirement he was a most effective head of state mines inspectorates, first in Silesia (Breslau; now Wroclaw, Poland), later in Westphalia (Dortmund). During his working life he served in all the important mining districts of Prussia, and travelled to mining areas in other parts of Germany, Belgium, France and Britain. In the 1820s, after visiting Glenck's well-known saltworks near Wimpfen, he was commissioned to search for salt deposits in Prussian territory, where he discovered the thermal springs south of Minden which later became the renowned spa carrying his name.

With deeper drills, the increased weight of the rods made it difficult to disengage the drill on each stroke and made the apparatus self-destructive on impact of the drill. Oeynhausen, from 1834, used fish joints, flexible connections between the drill and the rods. Not only did they prevent destructive impact, but they also gave a jerk on the return stroke that facilitated disengagements. He never claimed to have invented the fish joints: in fact, they appeared almost simultaneously in Europe and in America at that time, and had been used since at least the seventeenth century in China, although they were unknown in the Western hemisphere.

Using fish joints meant the start of a new era in deep-drilling, allowing much deeper wells to be sunk than before. Five weeks after Oeynhausen, K.G. Kind operated with a different kind of fish joint, and in 1845 another Prussian mining officer, Karl Leopold Fabian (1782–1855), Director of the salt inspectorate at Schönebeck, Elbe, improved the fish joints by developing a special device between the rod and the drill to enable the chisel, strengthened by a sinker bar, to fall onto the bottom of the hole without hindrance with a higher effect. The free-fall system became another factor in the outstanding results of deep-drilling in Prussia in the nineteenth century.

An engineer and agriculturalist who had to travel long distances over rough country, he evolved an improved design of velocipede. The original device appears to have been first shown in the gardens of the Palais Royal by the comte de Sivrac in 1791, a small wooden "horse" fitted with two wheels and propelled by the rider's legs thrusting alternately against the ground. It was not possible to turn the front wheel to steer the machine, a small variation from the straight being obtained by the rider leaning sideways. It is not known if de Sivrac was the inventor of the machine: it is likely that it had been in existence, probably as a child's toy, for a number of years. Its original name was the celerifière, but it was renamed the velocifère in 1793. The Baron's Draisienne was an improvement on this primitive machine; it had a triangulated wooden frame, an upholstered seat, a rear luggage seat and an armrest which took the thrust of the rider as he or she pushed against the ground. Furthermore, it was steerable. In some models there was a cordoperated brake and a prop stand, and the seat height could be adjusted. At least one machine was fitted with a milometer. Drais began limited manufacture and launched a long marketing and patenting campaign, part of which involved sending advertising letters to leading figures, including a number of kings.

The Draisienne was first shown in public in April 1817: a ladies' version became available in 1819. Von Drais took out a patent in Baden on 12 January 1818 and followed with a French patent on 17 February. Three-and four-wheeled versions became available so the two men could take the ladies for a jaunt.

Drais left his agricultural and forestry work and devoted his full time to the "Running Machine" business. Soon copies were being made and sold in Italy, Germany and Austria. In London, a Denis Johnson took out a patent in December 1818 for a "pedestrian curricle" which was soon nicknamed the dandy horse.

Educated at the Polytechnic Institute in Vienna, Voigtländer travelled widely before taking over the family business in 1837. The business had been founded by Voigtländer's grandfather in 1756, and was continued by his father, Johann Friedrich, the inventor of the opera glass, and by the 1830s enjoyed one of the highest reputations in Europe. When Petzval made the calculations for the first purpose-designed photographic objective in 1840, it was inevitable that he should go to Peter Voigtländer for advice. The business went on to manufacture Petzval's lens, which was also fitted to an all-metal camera of totally original design by Voigtländer.

The Petzval lens was an extraordinary commercial success and Voigtländer sold specimens all over the world. Unfortunately Petzval had no formal agreement with Voigtländer and made little financial gain from his design, a fact which was to lead to dispute and separation; the Voigtländer concern continued to prosper, however. To meet the increasing demand for his products, Peter Voigtländer built a new factory in Brunswick and closed the business in Vienna. The closure is seen by at least one commentator as the death blow to Vienna's optical industry, a field in which it was once preeminent. The Voigtländer dynasty continued long after Peter's death and the name enjoyed a reputation for high-quality photographic equipment well into the twentieth century.

    My head swam as I stood erect. I perceived that I was sickening from excitement and inanition: neither meat nor drink had passed my lips that day, for I had taken no breakfast (Ch. Bronte). Oh, my lord, no food had passed your lips since the morning of yesterday. I beseech you to take at least a few mouthfuls (W. S. Maugham)
