104 Carver, George Washington
SUBJECT AREA: Agricultural and food technology[br]b. 1861 USAd. 1943 USA[br]African-American agriculturalist.[br]In 1896 Carver was invited by Booker T.Washington, noted for his efforts to improve the education of African American craftspeople after the Civil War, to join the teaching staff at the Tuskegee Institute, Alabama. Carver became renowned for his innovative work in developing agricultural products, particularly from the peanut, sweet potato and cowpea. He was one of the first agriculturalists of that time to promote the use of organic fertilizers, and he was noted for his work in the hybridization of local plants. In spite of these achievements, his immediate impact on the African American farming community lay in promoting agricultural education and extension work. In 1897 Carver was appointed the first director of the Tuskegee agricultural experiment station. Here, he developed teaching techniques in agricultural education, such as issuing a series of clearly-written information bulletins. He also devised the first mobile school in the American South, which consisted of a farm wagon equipped with educational material and travelled from farm to farm, demonstrating the latest agricultural techniques.Carver was granted only three patents: one in 1923 for a cosmetic and two, in 1925 and 1927, for processes for making pigments.[br]Further ReadingP.P.James, 1989, The Real McCoy: African American Invention and Innovation 2619– 1930, Washington, DC: Smithsonian Institution Press, 69–70.LRDBiographical history of technology > Carver, George Washington

105 Lawes, Sir John Bennet
SUBJECT AREA: Agricultural and food technology[br]b. 28 December 1814 Rothamsted, Hertfordshire, Englandd. 31 August 1900 Rothamsted, Hertfordshire, England[br]English scientific agriculturalist.[br]Lawes's education at Eton and Oxford did little to inform his early taste for chemistry, which he developed largely on his own. By the age of 20 he had fitted up the best bedroom in his house as a fully equipped chemical laboratory. His first interest was in the making of drugs; it was said that he knew the Pharmacopoeia, by heart. He did, however, receive some instruction from Anthony Todd Thomson of University College, London. His father having died in 1822, Lawes entered into possession of the Rothamsted estate when he came of age in 1834. He began experiments with plants with uses as drugs, but following an observation by a neighbouring farmer of the effect of bones on the growth of certain crops Lawes turned to experiments with bones dissolved in sulphuric acid on his turnip crop. The results were so promising that he took out a patent in 1842 for converting mineral and fossil phosphates into a powerful manure by the action of sulphuric acid. The manufacture of these superphosphates became a major industry of tremendous benefit to agriculture. Lawes himself set up a factory at Deptford in 1842 and a larger one in 1857 at Barking Creek, both near London. The profits from these and other chemical manufacturing concerns earned Lawes profits which funded his experimental work at Rothamsted. In 1843, Lawes set up the world's first agricultural experiment station. Later in the same year he was joined by Joseph Henry Gilbert, and together they carried out a considerable number of experiments of great benefit to agriculture, many of the results of which were published in the leading scientific journals of the day, including the Philosophical Transactions of the Royal Society. In all, 132 papers were published, most of them jointly with Gilbert. A main theme of the work on plants was the effect of various chemical fertilizers on the growth of different crops, compared with the effects of farm manure and of no treatment at all. On animal rearing, they studied particularly the economical feeding of animals.The work at Rothamsted soon brought Lawes into prominence; he joined the Royal Agricultural Society in 1846 and became a member of its governing body two years later, a position he retained for over fifty years. Numerous distinctions followed and Rothamsted became a place of pilgrimage for people from many parts of the world who were concerned with the application of science to agriculture. Rothamsted's jubilee in 1893 was marked by a public commemoration headed by the Prince of Wales.[br]Principal Honours and DistinctionsBaronet 1882. FRS 1854.

106 Sauerbrun, Charles de, Baron von Drais
SUBJECT AREA: Land transport[br]b. 1785d. 1851[br]German popularizer of the first form of manumotive vehicle, the hobby-horse.[br]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.[br]Further ReadingC.A.Caunter, 1955, Cycles: History and Development, London: Science Museum and HMSO.IMcNBiographical history of technology > Sauerbrun, Charles de, Baron von Drais
