30 Land, Edwin Herbert
SUBJECT AREA: Photography, film and optics[br]b. 7 May 1909 Bridgeport, Connecticut, USAd. 1 March 1991 Cambridge, Massachusetts, USA[br]American scientist and inventor of the Polaroid instant-picture process.[br]Edwin Land's career began when, as a Harvard undergraduate in the late 1920s, he became interested in the possibility of developing a polarizing filter in the form of a thin sheet, to replace the crystal and stacked-glass devices then in use, which were expensive, cumbersome and limited in size. He succeeded in creating a material in which minute anisotropic iodine crystals were oriented in line, producing an efficient polarizer that was patented in 1929. After presenting the result of his researches in a Physics Department colloquium at Harvard, he left to form a partnership with George Wheelwright to manufacture the new material, which was seen to have applications as diverse as anti-glare car headlights, sunglasses, and viewing filters for stereoscopic photographs and films. In 1937 he founded the Polaroid Corporation and developed the Vectograph process, in which self-polarized photographic images could be printed, giving a stereoscopic image when viewed through polarizing viewers. Land's most significant invention, the instant picture, was stimulated by his three-year-old daughter. As he took a snapshot of her, she asked why she could not see the picture at once. He began to research the possibility, and on 21 February 1947 he demonstrated a system of one-step photography at a meeting of the Optical Society of America. Using the principle of diffusion transfer of the image, it produced a photograph in one minute. The Polaroid Land camera was launched on 26 November 1948. The original sepia-coloured images were soon replaced by black and white and, in 1963, by Polacolor instant colour film. The original peel-apart "wet" process was superseded in 1972 with the introduction of the SX-70 camera with dry picture units which developed in the light. The instant colour movie system Polavision, introduced in 1978, was less successful and was one of his few commercial failures.Land died in March 1991, after a career in which he had been honoured by countless scien-tific and academic bodies and had received the Medal of Freedom, the highest civilian honour in America.[br]Principal Honours and DistinctionsMedal of Freedom.BC -
31 Radcliffe, William
SUBJECT AREA: Textiles[br]b. 1761 Mellor, Cheshire, Englandd. 1842 Mellor, Cheshire, England[br]English inventor of the sizing machine.[br]Radcliffe was brought up in the textile industry and learned carding and spinning as a child. When he was old enough, he became a weaver. It was a time when there were not enough weavers to work up all the yarn being spun on the recently invented spinning machines, so some yarn was exported. Radcliffe regarded this as a sin; meetings were held to prohibit the export, and Radcliffe promised to use his best endeavours to discover means to work up the yarn in England. He owned a mill at Mellor and by 1801 was employing over 1,000 hand-loom weavers. He wanted to improve their efficiency so they could compete against power looms, which were beginning to be introduced at that time.His first step was to divide up as much as possible the different weaving processes, not unlike the plan adopted by Arkwright in spinning. In order to strengthen the warp yarns made of cotton and to reduce their tendency to fray during weaving, it was customary to apply an adhesive substance such as starch paste. This was brushed on as the warp was unwound from the back beam during weaving, so only short lengths could be treated before being dried. Instead of dressing the warp in the loom as was hitherto done, Radcliffe had it dressed in a separate machine, relieving the weaver of the trouble and saving the time wasted by the method previously used. Radcliffe employed a young man names Thomas Johnson, who proved to be a clever mechanic. Radcliffe patented his inventions in Johnson's name to avoid other people, especially foreigners, finding out his ideas. He took out his first patent, for a dressing machine, in March 1803 and a second the following year. The combined result of the two patents was the introduction of a beaming machine and a dressing machine which, in addition to applying the paste to the yarns and then drying them, wound them onto a beam ready for the loom. These machines enabled the weaver to work a loom with fewer stoppages; however, Radcliffe did not anticipate that his method of sizing would soon be applied to power looms as well and lead to the commercial success of powered weaving. Other manufacturers quickly adopted Radcliffe's system, and Radcliffe himself soon had to introduce power looms in his own business.Radcliffe improved the hand looms themselves when, with the help of Johnson, he devised a cloth taking-up motion that wound the woven cloth onto a roller automatically as the weaver operated the loom. Radcliffe and Johnson also developed the "dandy loom", which was a more compact form of hand loom and was also later adapted for weaving by power. Radcliffe was among the witnesses before the Parliamentary Committee which in 1808 awarded Edmund Cartwright a grant for his invention of the power loom. Later Radcliffe was unsuccessfully to petition Parliament for a similar reward for his contributions to the introduction of power weaving. His business affairs ultimately failed partly through his own obstinacy and his continued opposition to the export of cotton yarn. He lived to be 81 years old and was buried in Mellor churchyard.[br]Bibliography1811, Exportation of Cotton Yarn and Real Cause of the Distress that has Fallen upon the Cotton Trade for a Series of Years Past, Stockport.1828, Origin of the New System of Manufacture, Commonly Called "Power-Loom Weaving", Stockport (this should be read, even though it is mostly covers Radcliffe's political aims).Further ReadingA.Barlow, 1870, The History and Principles of Weaving by Hand and by Power, London (provides an outline of Radcliffe's life and work).W.English, 1969, The Textile Industry, London (a general background of his inventions).
