121 McKay, Hugh Victor
SUBJECT AREA: Agricultural and food technology[br]b. c. 1866 Drummartin, Victoria, Australiad. 21 May 1926 Australia[br]Australian inventor and manufacturer of harvesting and other agricultural equipment.[br]A farmer's son, at the age of 17 McKay developed modifications to the existing stripper harvester and created a machine that would not only strip the seed from standing corn, but was able to produce a threshed, winnowed and clean sample in one operation. The prototype was produced in 1884 and worked well on the two acres of wheat that had been set aside on the family farm. By arrangement with a Melbourne plough maker, five machines were made and sold for the 1885 season. In 1886 the McKay Harvester Company was formed, with offices at Ballarat, from which the machines, built by various companies, were sold. The business expanded quickly, selling sixty machines in 1888, and eventually rising to the production of nearly 2,000 harvesters in 1905. The name "Sunshine" was given to the harvester, and the "Sun" prefix was to appear on all other implements produced by the company as it diversified its production interests. In 1902 severe drought reduced machinery sales and left 2,000 harvesters unsold. McKay was forced to look to export markets to dispose of his surplus machines. By 1914 a total of 10,000 machines were being exported annually. During the First World War McKay was appointed to the Business Board of the Defence Department. Increases in the scale of production resulted in the company moving to Melbourne, where it was close to the port of entry of raw materials and was able to export the finished article more readily. In 1909 McKay produced one of the first gas-engined harvesters, but its cost prevented it from being more than an experimental prototype. By this time McKay was the largest agricultural machinery manufacturer in the Southern hemisphere, producing a wide range of implements, including binders. In 1916 McKay hired Headlie Taylor, who had developed a machine capable of harvesting fallen crops. The jointly developed machine was a major success, coming as it did in what would otherwise have been a disastrous Australian harvest. Further developments included the "Sun Auto-header" in 1923, the first of the harvesting machines to adopt the "T" configuration to be seen on modern harvesters. The Australian market was expanding fast and a keen rivalry developed between McKay and Massey Harris. Confronted by the tariff regulations with which the Australian Government had protected its indigenous machinery industry since 1906, Massey Harris sold all its Australian assets to the H.V. McKay company in 1930. Twenty-three years later Massey Ferguson acquired the old Sunshine works and was still operating from there in the 1990s.Despite a long-running history of wage disputes with his workforce, McKay established a retiring fund as well as a self-help fund for distressed cases. Before his death he created a charitable trust and requested that some funds should be made available for the "aerial experiments" which were to lead to the establishment of the Flying Doctor Service.[br]Principal Honours and DistinctionsCBE.Further ReadingGraeme Quick and Wesley Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (devotes a chapter to the unique development of harvesting machinery which took place in Australia).AP -
122 Muybridge, Eadweard
SUBJECT AREA: Photography, film and optics[br]b. 9 April 1830 Kingston upon Thames, Englandd. 8 May 1904 Kingston upon Thames, England[br]English photographer and pioneer of sequence photography of movement.[br]He was born Edward Muggeridge, but later changed his name, taking the Saxon spelling of his first name and altering his surname, first to Muygridge and then to Muybridge. He emigrated to America in 1851, working in New York in bookbinding and selling as a commission agent for the London Printing and Publishing Company. Through contact with a New York daguerreotypist, Silas T.Selleck, he acquired an interest in photography that developed after his move to California in 1855. On a visit to England in 1860 he learned the wet-collodion process from a friend, Arthur Brown, and acquired the best photographic equipment available in London before returning to America. In 1867, under his trade pseudonym "Helios", he set out to record the scenery of the Far West with his mobile dark-room, christened "The Flying Studio".His reputation as a photographer of the first rank spread, and he was commissioned to record the survey visit of Major-General Henry W.Halleck to Alaska and also to record the territory through which the Central Pacific Railroad was being constructed. Perhaps because of this latter project, he was approached by the President of the Central Pacific, Leland Stanford, to attempt to photograph a horse trotting at speed. There was a long-standing controversy among racing men as to whether a trotting horse had all four hooves off the ground at any point; Stanford felt that it did, and hoped than an "instantaneous" photograph would settle the matter once and for all. In May 1872 Muybridge photographed the horse "Occident", but without any great success because the current wet-collodion process normally required many seconds, even in a good light, for a good result. In April 1873 he managed to produce some better negatives, in which a recognizable silhouette of the horse showed all four feet above the ground at the same time.Soon after, Muybridge left his young wife, Flora, in San Francisco to go with the army sent to put down the revolt of the Modoc Indians. While he was busy photographing the scenery and the combatants, his wife had an affair with a Major Harry Larkyns. On his return, finding his wife pregnant, he had several confrontations with Larkyns, which culminated in his shooting him dead. At his trial for murder, in February 1875, Muybridge was acquitted by the jury on the grounds of justifiable homicide; he left soon after on a long trip to South America.He again took up his photographic work when he returned to North America and Stanford asked him to take up the action-photography project once more. Using a new shutter design he had developed while on his trip south, and which would operate in as little as 1/1,000 of a second, he obtained more detailed pictures of "Occident" in July 1877. He then devised a new scheme, which Stanford sponsored at his farm at Palo Alto. A 50 ft (15 m) long shed was constructed, containing twelve cameras side by side, and a white background marked off with vertical, numbered lines was set up. Each camera was fitted with Muybridge's highspeed shutter, which was released by an electromagnetic catch. Thin threads stretched across the track were broken by the horse as it moved along, closing spring electrical contacts which released each shutter in turn. Thus, in about half a second, twelve photographs were obtained that showed all the phases of the movement.Although the pictures were still little more than silhouettes, they were very sharp, and sequences published in scientific and photographic journals throughout the world excited considerable attention. By replacing the threads with an electrical commutator device, which allowed the release of the shutters at precise intervals, Muybridge was able to take series of actions by other animals and humans. From 1880 he lectured in America and Europe, projecting his results in motion on the screen with his Zoopraxiscope projector. In August 1883 he received a grant of $40,000 from the University of Pennsylvania to carry on his work there. Using the vastly improved gelatine dry-plate process and new, improved multiple-camera apparatus, during 1884 and 1885 he produced over 100,000 photographs, of which 20,000 were reproduced in Animal Locomotion in 1887. The subjects were animals of all kinds, and human figures, mostly nude, in a wide range of activities. The quality of the photographs was extremely good, and the publication attracted considerable attention and praise.Muybridge returned to England in 1894; his last publications were Animals in Motion (1899) and The Human Figure in Motion (1901). His influence on the world of art was enormous, over-turning the conventional representations of action hitherto used by artists. His work in pioneering the use of sequence photography led to the science of chronophotography developed by Marey and others, and stimulated many inventors, notably Thomas Edison to work which led to the introduction of cinematography in the 1890s.[br]Bibliography1887, Animal Locomotion, Philadelphia.1893, Descriptive Zoopraxography, Pennsylvania. 1899, Animals in Motion, London.1901, The Human Figure in Motion, London.Further Reading1973, Eadweard Muybridge: The Stanford Years, Stanford.G.Hendricks, 1975, Muybridge: The Father of the Motion Picture, New York.
