123 Braun, Wernher Manfred von
[br]b. 23 March 1912 Wirsitz, Germanyd. 16 June 1977 Alexandria, Virginia, USA[br]German pioneer in rocket development.[br]Von Braun's mother was an amateur astronomer who introduced him to the futuristic books of Jules Verne and H.G.Wells and gave him an astronomical telescope. He was a rather slack and undisciplined schoolboy until he came across Herman Oberth's book By Rocket to Interplanetary Space. He discovered that he required a good deal of mathematics to follow this exhilarating subject and immediately became an enthusiastic student.The Head of the Ballistics and Armaments branch of the German Army, Professor Karl Becker, had asked the engineer Walter Dornberger to develop a solid-fuel rocket system for short-range attack, and one using liquid-fuel rockets to carry bigger loads of explosives beyond the range of any known gun. Von Braun joined the Verein für Raumschiffsfahrt (the German Space Society) as a young man and soon became a leading member. He was asked by Rudolf Nebel, VfR's chief, to persuade the army of the value of rockets as weapons. Von Braun wisely avoided all mention of the possibility of space flight and some financial backing was assured. Dornberger in 1932 built a small test stand for liquid-fuel rockets and von Braun built a small rocket to test it; the success of this trial won over Dornberger to space rocketry.Initially research was carried out at Kummersdorf, a suburb of Berlin, but it was decided that this was not a suitable site. Von Braun recalled holidays as a boy at a resort on the Baltic, Peenemünde, which was ideally suited to rocket testing. Work started there but was not completed until August 1939, when the group of eighty engineers and scientists moved in. A great fillip to rocket research was received when Hitler was shown a film and was persuaded of the efficacy of rockets as weapons of war. A factory was set up in excavated tunnels at Mittelwerk in the Harz mountains. Around 6,000 "vengeance" weapons were built, some 3,000 of which were fired on targets in Britain and 2,000 of which were still in storage at the end of the Second World War.Peenemünde was taken by the Russians on 5 May 1945, but by then von Braun was lodging with many of his colleagues at an inn, Haus Ingeburg, near Oberjoch. They gave themselves up to the Americans, and von Braun presented a "prospectus" to the Americans, pointing out how useful the German rocket team could be. In "Operation Paperclip" some 100 of the team were moved to the United States, together with tons of drawings and a number of rocket missiles. Von Braun worked from 1946 at the White Sands Proving Ground, New Mexico, and in 1950 moved to Redstone Arsenal, Huntsville, Alabama. In 1953 he produced the Redstone missile, in effect a V2 adapted to carry a nuclear warhead a distance of 320 km (199 miles). The National Aeronautics and Space Administration (NASA) was formed in 1958 and recruited von Braun and his team. He was responsible for the design of the Redstone launch vehicles which launched the first US satellite, Explorer 1, in 1958, and the Mercury capsules of the US manned spaceflight programme which carried Alan Shepard briefly into space in 1961 and John Glenn into earth orbit in 1962. He was also responsible for the Saturn series of large, staged launch vehicles, which culminated in the Saturn V rocket which launched the Apollo missions taking US astronauts for the first human landing on the moon in 1969. Von Braun announced his resignation from NASA in 1972 and died five years later.[br]Bibliography1981, with F.L.Ordway, History of Rocketry and Space TravelFurther ReadingP.Marsh, 1985, The Space Business, Penguin.

124 Lee, Edmund
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]d. mid-1763 Brock Mill, Wigan, England[br]English inventor of the fantail, used to turn windmills automatically to face the wind.[br]On 9 December 1745 Edmund Lee was granted letters patent for his invention of the windmill fantail. In the preamble to Lee's patent he is described as a smith of Brock Mill, near Wigan, where he ran a millwright's business. Brock Mill is known to have been a substantial water-powered iron forge by the River Douglas to the north of Wigan. The drawing accompanying the patent shows a tower mill with its tail pole reaching the ground, and this is connected to a frame or carriage supporting a seven-bladed wind wheel. This tail projected some distance from the back of the tower, and when the wind caught it and turned it the cap was turned to face the wind by means of the gears which linked the cap to the fantail. The next logical step from Lee's invention was to place the fantail at a high level on the cap or at the foot of the ladder of a post mill. There is also an inferred connection between the Lee fantail and the annular sail of the wind engine or of a windmill such as that at Haverhill in Suffolk.[br]Further ReadingStephen Buckland, 1987, Lee's Patent Windmill, London KM -
125 Porta, Giovanni Battista (Giambattista) della
SUBJECT AREA: Steam and internal combustion engines[br]b. between 3 October and 15 November 1535 Vico Equense, near Naples, Italyd. 4 February 1615 Naples, Italy[br]Italian natural philosopher who published many scientific books, one of which covered ideas for the use of steam.[br]Giambattista della Porta spent most of his life in Naples, where some time before 1580 he established the Accademia dei Segreti, which met at his house. In 1611 he was enrolled among the Oziosi in Naples, then the most renowned literary academy. He was examined by the Inquisition, which, although he had become a lay brother of the Jesuits by 1585, banned all further publication of his books between 1592 and 1598.His first book, the Magiae Naturalis, which covered the secrets of nature, was published in 1558. He had been collecting material for it since the age of 15 and he saw that science should not merely represent theory and contemplation but must arrive at practical and experimental expression. In this work he described the hardening of files and pieces of armour on quite a large scale, and it included the best sixteenth-century description of heat treatment for hardening steel. In the 1589 edition of this work he covered ways of improving vision at a distance with concave and convex lenses; although he may have constructed a compound microscope, the history of this instrument effectively begins with Galileo. His theoretical and practical work on lenses paved the way for the telescope and he also explored the properties of parabolic mirrors.In 1563 he published a treatise on cryptography, De Furtivis Liter arum Notis, which he followed in 1566 with another on memory and mnemonic devices, Arte del Ricordare. In 1584 and 1585 he published treatises on horticulture and agriculture based on careful study and practice; in 1586 he published De Humana Physiognomonia, on human physiognomy, and in 1588 a treatise on the physiognomy of plants. In 1593 he published his De Refractione but, probably because of the ban by the Inquisition, no more were produced until the Spiritali in 1601 and his translation of Ptolemy's Almagest in 1605. In 1608 two new works appeared: a short treatise on military fortifications; and the De Distillatione. There was an important work on meteorology in 1610. In 1601 he described a device similar to Hero's mechanisms which opened temple doors, only Porta used steam pressure instead of air to force the water out of its box or container, up a pipe to where it emptied out into a higher container. Under the lower box there was a small steam boiler heated by a fire. He may also have been the first person to realize that condensed steam would form a vacuum, for there is a description of another piece of apparatus where water is drawn up into a container at the top of a long pipe. The container was first filled with steam so that, when cooled, a vacuum would be formed and water drawn up into it. These are the principles on which Thomas Savery's later steam-engine worked.[br]Further ReadingDictionary of Scientific Biography, 1975, Vol. XI, New York: C.Scribner's Sons (contains a full biography).H.W.Dickinson, 1938, A Short History of the Steam Engine, Cambridge University Press (contains an account of his contributions to the early development of the steam-engine).C.Singer (ed.), 1957, A History of Technology, Vol. III, Oxford University Press (contains accounts of some of his other discoveries).I.Asimov (ed.), 1982, Biographical Encyclopaedia of Science and Technology, 2nd edn., New York: Doubleday.G.Sarton, 1957, Six wings: Men of Science in the Renaissance, London: Bodley Head, pp. 85–8.RLH / IMcNBiographical history of technology > Porta, Giovanni Battista (Giambattista) della

126 Siemens, Dr Ernst Werner von
[br]b. 13 December 1816 Lenthe, near Hanover, Germanyd. 6 December 1892 Berlin, Germany[br]German pioneer of the dynamo, builder of the first electric railway.[br]Werner von Siemens was the eldest of a large family and after the early death of his parents took his place at its head. He served in the Prussian artillery, being commissioned in 1839, after which he devoted himself to the study of chemistry and physics. In 1847 Siemens and J.G. Halske formed a company, Telegraphen-Bauanstalt von Siemens und Halske, to manufacture a dial telegraph which they had developed from an earlier instrument produced by Charles Wheatstone. In 1848 Siemens obtained his discharge from the army and he and Halske constructed the first long-distance telegraph line on the European continent, between Berlin and Frankfurt am Main.Werner von Siemens's younger brother, William Siemens, had settled in Britain in 1844 and was appointed agent for the Siemens \& Halske company in 1851. Later, an English subsidiary company was formed, known from 1865 as Siemens Brothers. It specialized in manufacturing and laying submarine telegraph cables: the specialist cable-laying ship Faraday, launched for the purpose in 1874, was the prototype of later cable ships and in 1874–5 laid the first cable to run direct from the British Isles to the USA. In charge of Siemens Brothers was another brother, Carl, who had earlier established a telegraph network in Russia.In 1866 Werner von Siemens demonstrated the principle of the dynamo in Germany, but it took until 1878 to develop dynamos and electric motors to the point at which they could be produced commercially. The following year, 1879, Werner von Siemens built the first electric railway, and operated it at the Berlin Trades Exhibition. It comprised an oval line, 300 m (985 it) long, with a track gauge of 1 m (3 ft 3 1/2 in.); upon this a small locomotive hauled three small passenger coaches. The locomotive drew current at 150 volts from a third rail between the running rails, through which it was returned. In four months, more than 80,000 passengers were carried. The railway was subsequently demonstrated in Brussels, and in London, in 1881. That same year Siemens built a permanent electric tramway, 1 1/2 miles (2 1/2 km) long, on the outskirts of Berlin. In 1882 in Berlin he tried out a railless electric vehicle which drew electricity from a two-wire overhead line: this was the ancestor of the trolleybus.In the British Isles, an Act of Parliament was obtained in 1880 for the Giant's Causeway Railway in Ireland with powers to work it by "animal, mechanical or electrical power"; although Siemens Brothers were electrical engineers to the company, of which William Siemens was a director, delays in construction were to mean that the first railway in the British Isles to operate regular services by electricity was that of Magnus Volk.[br]Principal Honours and DistinctionsHonorary doctorate, Berlin University 1860.

127 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.
