Belling was educated at Burts Grammar School in Lostwithiel, Cornwall, and at Crossley Schools in Halifax, Yorkshire. In 1903 he was apprenticed to Crompton \& Co. at Chelmsford in Essex, the firm that in 1894 offered for sale the earliest electric heaters. These electric radiant panels were intended as heating radiators or cooking hotplates, but were not very successful because, being cast-iron panels into which heating wires had been embedded in enamel, they tended to fracture due to the different rates of thermal expansion of the iron and the enamel. Other designs of electric heaters followed, notably the introduction of large, sausage-shaped carbon filament bulbs fitted into a fire frame and backed by reflectors. This was the idea of H. Dowsing, a collaborator of Crompton, in 1904.

After qualifying in 1906, Belling left Crompton \& Co. and went to work for Ediswan at Ponders End in Hertfordshire. He left in 1912 to set up his own business, which he began in a small shed in Enfield. With a small staff and capital of £450, he took out his first patent for his wire-wound-former electric fire in the same year. The resistance wire, made from nickel-chrome alloy such as that patented in 1906 by A.L. Marsh, was coiled round a clay former. Six such bars were attached to a cast-iron frame with heating control knobs, and the device was marketed as the Standard Belling Fire. Advertised in 1912, the fire was an immediate success and was followed by many other variations. Improvements to the first model included wire safety guards, enamel finishes and a frame ornamented with copper and brass.

Belling turned his attention to hotplates, cookers, immersion heaters, electric irons, water urns and kettles, producing the Modernette Cooker (1919), the multi-parabola fire bar (1921), the plate and dish warmer (1924), the storage heater (1926) and the famous Baby Belling cookers, the first of which appeared in 1929. By 1955 business had developed so well that Belling opened another factory at Burnley, Lancashire. He partly underwrote, for the amount of £1 million, a proposed scientific technical college for the electrical industry at Enfield.

Crompton was the youngest son of a widely travelled diplomat who had retired to the country and become a Whig MP after the Reform Act of 1832. During the Crimean War Crompton's father was in Gibraltar as a commander in the militia. Young Crompton enrolled as a cadet and sailed to Sebastopol, visiting an older brother, and, although only 11 years old, he qualified for the Crimean Medal. Returning to England, he was sent to Harrow, where he showed an aptitude for engineering. In the holidays he made a steam road engine on his father's estate. On leaving school he was commissioned into the Rifle Brigade and spent four years in India, where he worked on a system of steam road haulage to replace bullock trains. Leaving the Army in 1875, Crompton bought a share in an agricultural and general engineering business in Chelmsford, intending to develop his interests in transport. He became involved in the newly developing technology of electric arc lighting and began importing electric lighting equipment made by Gramme in Paris. Crompton soon decided that he could manufacture better equipment himself, and the Chemlsford business was transformed into Crompton \& Co., electrical engineers. After lighting a number of markets and railway stations, Crompton won contracts for lighting the new Law Courts in London, in 1882, and the Ring Theatre in Vienna in 1883. Crompton's interests then broadened to include domestic electrical appliances, especially heating and cooking apparatus, which provided a daytime load when lighting was not required. In 1899 he went to South Africa with the Electrical Engineers Volunteer Corps, providing telegraphs and searchlights in the Boer War. He was appointed Engineer to the new Road Board in 1910, and during the First World War worked for the Government on engineering problems associated with munitions and tanks. He believed strongly in the value of engineering standards, and in 1906 became the first Secretary of the International Electrotechnical Commission.

Frederick W.Howe attended local schools until the age of 16 and then entered the machine shop of Gay \& Silver at North Chelmsford, Massachusetts, as an apprentice and remained with that firm for nine years. He then joined Robbins, Kendall \& Lawrence of Windsor, Vermont, as Assistant to Richard S. Lawrence in designing machine tools. A year later (1848) he was made Plant Superintendent. During his time with this firm, Howe designed a profiling machine which was used in all gun shops in the United States: a barrel-drilling and rifling machine, and the first commercially successful milling machine. Robbins \& Lawrence took to the Great Exhibition of 1851 in London, England, a set of rifles built on the interchangeable system. The interest this created resulted in a visit of some members of the British Royal Small Arms Commission to America and subsequently in an order for 150 machine tools, jigs and fixtures from Robbins \& Lawrence, to be installed at the small-arms factory at Enfield. From 1853 to 1856 Howe was in charge of the design and building of these machines. In 1856 he established his own armoury at Newark, New Jersey, but transferred after two years to Middletown, Connecticut, where he continued the manufacture of small arms until the outbreak of the Civil War. He then became Superintendent of the armoury of the Providence Tool Company at Providence, Rhode Island, and served in that capacity until the end of the war. In 1865 he went to Bridgeport, Connecticut, to assist Elias Howe with the manufacture of his sewing machine. After the death of Elias Howe, Frederick Howe returned to Providence to join the Brown \& Sharpe Manufacturing Company. As Superintendent of that establishment he worked with Joseph R. Brown in the development of many of the firm's products, including machinery for the Wilcox \& Gibbs sewing machine then being made by Brown \& Sharpe. From 1876 Howe was in business on his own account as a consulting mechanical engineer and in his later years he was engaged in the development of shoe machinery and in designing a one-finger typewriter, which, however, was never completed. He was granted several patents, mainly in the fields of machine tools and firearms. As a designer, Howe was said to have been a perfectionist, making frequent improvements; when completed, his designs were always sound.

Kapp entered the Polytechnic School in Zurich in 1869 and gained a mechanical engineering diploma. He became a member of the engineering staff at the Vienna International Exhibition of 1873, and then spent some time in the Austrian navy before entering the service of Gwynne \& Co. of London, where he designed centrifugal pumps and gas exhausters. Kapp resolved to become an electrical engineer after a visit to the Paris Electrical Exhibition of 1881 and in the following year was appointed Manager of the Crompton Co. works at Chelmsford. There he developed and patented the dynamo with compound field winding. Also at that time, with Crompton, he patented electrical measuring instruments with over-saturated electromagnets. He became a naturalized British subject in 1881.

In 1886 Kapp's most influential paper was published. This described his concept of the magnetic circuit, providing for the first time a sound theoretical basis for dynamo design. The theory was also developed independently by J. Hopkinson. After commencing practice as a consulting engineer in 1884 he carried out design work on dynamos and also electricity-supply and -traction schemes in Germany, Italy, Norway, Russia and Switzerland. From 1891 to 1894 much of his time was spent designing a new generating station in Bristol, officially as Assistant to W.H. Preece. There followed an appointment in Germany as General Secretary of the Verband Deutscher Electrotechniker. For some years he edited the Electrotechnische Zeitschrift and was also a part-time lecturer at the Charlottenberg Technical High School in Berlin. In 1904 Kapp was invited to accept the new Chair of Electrical Engineering at the University of Birmingham, which he occupied until 1919. He was the author of several books on electrical machine and transformer design.
