22 Bakewell, Robert
SUBJECT AREA: Agricultural and food technology[br]b. 23 May 1725 Loughborough, Englandd. 1 October 1795 Loughborough, England[br]English livestock breeder who pioneered the practice of progeny testing for selecting breeding stock; he is particularly associated with the development of the Improved Leicester breed of sheep.[br]Robert Bakewell was the son of the tenant farming the 500-acre (200 hectare) Dishley Grange Farm, near Loughborough, where he was born. The family was sufficiently wealthy to allow Robert to travel, which he began to do at an early age, exploring the farming methods of the West Country, Norfolk, Ireland and Holland. On taking over the farm he continued the development of the irrigation scheme begun by his father. Arthur Young visited the farm during his tour of east England in 1771. At that time it consisted of 440 acres (178 hectares), 110 acres (45 hectares) of which were arable, and carried a stock of 60 horses, 400 sheep and 150 other assorted beasts. Of the arable land, 30 acres (12 hectares) were under root crops, mainly turnips.Bakewell was not the first to pioneer selective breeding, but he was the first successfully to apply selection to both the efficiency with which an animal utilized its food, and its physical appearance. He always had a clear idea of the animal he wanted, travelled extensively to collect a range of animals possessing the characteristics he sought, and then bred from these towards his goal. He was aware of the dangers of inbreeding, but would often use it to gain the qualities he wanted. His early experiments were with Longhorn cattle, which he developed as a meat rather than a draught animal, but his most famous achievement was the development of the Improved Leicester breed of sheep. He set out to produce an animal that would put on the most meat in the least time and with the least feeding. As his base he chose the Old Leicester, but there is still doubt as to which other breeds he may have introduced to produce the desired results. The Improved Leicester was smaller than its ancestor, with poorer wool quality but with greatly improved meat-production capacity.Bakewell let out his sires to other farms and was therefore able to study their development under differing conditions. However, he made stringent rules for those who hired these animals, requiring the exclusive use of his rams on the farms concerned and requiring particular dietary conditions to be met. To achieve this control he established the Dishley Society in 1783. Although his policies led to accusations of closed access to his stock, they enabled him to keep a close control of all offspring. He thereby pioneered the process now recognized as "progeny testing".Bakewell's fame and that of his farm spread throughout the country and overseas. He engaged in an extensive correspondence and acted as host to all of influence in British and overseas agriculture, but it would appear that he was an over-generous host, since he is known to have been in financial difficulties in about 1789. He was saved from bankruptcy by a public subscription raised to allow him to continue with his breeding experiments; this experience may well have been the reason why he was such a staunch advocate of State funding of agricultural research.[br]Further ReadingWilliam Houseman, 1894, biography, Journal of the Royal Agricultural Society. 1–31.

23 Pasteur, Louis
[br]b. 27 December 1822 Dole, Franced. 28 September 1895 Paris, France[br]French chemist, founder of stereochemistry, developer of microbiology and immunology, and exponent of the germ theory of disease.[br]Sustained by the family tanning business in Dole, near the Swiss border, Pasteur's school career was undistinguished, sufficing to gain him entry into the teacher-training college in Paris, the Ecole Normale, There the chemical lectures by the great organic chemist J.B.A.Dumas (1800–84) fired Pasteur's enthusiasm for chemistry which never left him. Pasteur's first research, carried out at the Ecole, was into tartaric acid and resulted in the discovery of its two optically active forms resulting from dissymmetrical forms of their molecules. This led to the development of stereochemistry. Next, an interest in alcoholic fermentation, first as Professor of Chemistry at Lille University in 1854 and then back at the Ecole from 1857, led him to deny the possibility of spontaneous generation of animal life. Doubt had previously been cast on this, but it was Pasteur's classic research that finally established that the putrefaction of broth or the fermentation of sugar could not occur spontaneously in sterile conditions, and could only be caused by airborne micro-organisms. As a result, he introduced pasteurization or brief, moderate heating to kill pathogens in milk, wine and other foods. The suppuration of wounds was regarded as a similar process, leading Lister to apply Pasteur's principles to revolutionize surgery. In 1860, Pasteur himself decided to turn to medical research. His first study again had important industrial implications, for the silk industry was badly affected by diseases of the silkworm. After prolonged and careful investigation, Pasteur found ways of dealing with the two main infections. In 1868, however, he had a stroke, which prevented him from active carrying out experimentation and restricted him to directing research, which actually was more congenial to him. Success with disease in larger animals came slowly. In 1879 he observed that a chicken treated with a weakened culture of chicken-cholera bacillus would not develop symptoms of the disease when treated with an active culture. He compared this result with Jenner's vaccination against smallpox and decided to search for a vaccine against the cattle disease anthrax. In May 1881 he staged a demonstration which clearly showed the success of his new vaccine. Pasteur's next success, finding a vaccine which could protect against and treat rabies, made him world famous, especially after a person was cured in 1885. In recognition of his work, the Pasteur Institute was set up in Paris by public subscription and opened in 1888. Pasteur's genius transcended the boundaries between science, medicine and technology, and his achievements have had significant consequences for all three fields.[br]BibliographyPasteur published over 500 books, monographs and scientific papers, reproduced in the magnificent Oeuvres de Pasteur, 1922–39, ed.
