81 Luís I, King
(1838-89)King Luís I was the second son of Queen Maria II and Dom Fernando. When his older brother, King Pedro V, died suddenly in October 1861, he ascended the throne. Well-educated, with the temperament of a writer and artist, Luís probably preferred the literary life to politics and public affairs. In the history of Portugal's literature, Luís is noted for his translations into Portuguese of several of Shakespeare's plays. During his 28-year reign, Portugal experienced a phase of the Regeneration and, for part of the period after 1870, relatively stable politics and a lack of military intervention in public life. During his reign, too, there was material progress and great literary accomplishment; for example, the famous novels of José Maria Eça de Queirós and the poetry of Antero de Quental. While republicanism became a greater force after 1871, and the first republican deputy was elected to the Chamber of Deputies in 1878, this party and its ideology were not a threat to the monarchy until after the reign of Dom Luís. When King Luís died in 1889, he was succeeded by his oldest son, Dom Carlos, whose stormy reign witnessed the rise of republicanism and serious degeneration of the monarchy. -
82 Manuel I, king
(1469-1521)King Manuel I, named "The Fortunate" in Portuguese tradition, ruled from 1495 to 1521, the zenith of Portugal's world power and imperial strength. Manuel was the 14th king of Portugal and the ninth son of Infante Dom Fernando and Dona Brites, as well as the adopted son of King João II (r. 1481-95). Manuel ascended the throne when the royal heir, Dom Afonso, the victim of a riding accident, suddenly died. Manuel's three marriages provide a map of the royal and international history of the era. His first marriage (1497) was to the widow of Dom Afonso, son of King João II, late heir to the throne. The second (1500) was to the Infanta Dona Maria of Castile, and the third marriage (1518) was to Dona Leonor, sister of King Carlos V (Hapsburg emperor and king of Spain).Manuel's reign featured several important developments in government, such as the centralization of state power and royal absolutism; overseas expansion, namely the decision in 1495 to continue on from Africa to Asia and the building of an Asian maritime trade empire; and innovation and creativity in culture, with the emergence of the Manueline architectural style and the writings of Gil Vicente and others. There was also an impact on population and demography with the expulsion or forcible conversion of the Jews. In 1496, King Manuel I approved a decree that forced all Jews who would not become baptized as Christians to leave the country within 10 months. The Jews had been expelled from Spain in 1492. The economic impact on Portugal in coming decades or even centuries is debatable, but it is clear that a significant number of Jews converted and remained in Portugal, becoming part of the Portuguese establishment.King Manuel's decision in 1495, backed by a royal council and by the Cortes called that year, to continue the quest for Asia by means of seeking an all-water route from Portugal around Africa to India was momentous. Sponsorship of Vasco da Gama's first great voyage (1497-99) to India was the beginning of an era of unprecedented imperial wealth, power, and excitement. It became the official goal to create a maritime monopoly of the Asian spice trade and keep it in Portugal's hands. When Pedro Álvares Cabral's voyage from Lisbon to India was dispatched in 1500, its route was deliberately planned to swing southwest into the Atlantic, thus sighting "The Land of the Holy Cross," or Brazil, which soon became a Portuguese colony. Under King Manuel, the foundations were laid for Portugal's Brazilian and Asian empire, from Calicut to the Moluccas. Described by France's King Francis I as the "Grocer King," with his command of the mighty spice trade, King Manuel approved of a fitting monument to the new empire: the building of the magnificent Jerónimos Monastery where, after his death in 1521, both Manuel and Vasco da Gama were laid to rest. -
83 Pedro II, king
(1648- 1706)The 23rd king of Portugal who ascended the throne in 1668. This followed the 1667 coup d'etat that deposed Pedro's handicapped brother, King Afonso VI, who was later held under house arrest in the Azores and then in the National Palace of Sintra for the remainder of his life. Pedro then married his sister-in-law. During his reign, Pedro signed the great peace treaty of 1668 with Spain, thus ending the War of Restoration. With increased revenues from mineral exploitation in Brazil, Portugal's national finances under Pedro were strengthened. With his chief minister, the count of Eriçeira, Pedro promoted the establishment of early basic industries. -
84 Pedro V, king
(1837-1861)Of all Portuguese kings in the 18th and 19th centuries, Pedro V was the best educated and most intellectually talented. Pedro was the firstborn son of Queen Maria II and Prince Ferdinand of Saxe-Coburg-Gotha. Exceptionally well-educated, Prince Pedro traveled extensively abroad, which was unusual for a Portuguese royal heir in that day, and was tutored under his mother's watchful eye. He was blessed with a brilliant memory, a fine imagination, shrewd political judgment, and a fund of learning. Pedro demonstrated a keen interest not only in the common political affairs such as fell within a constitutional monarch's concerns, but with a variety of subjects including science, emigration, diplomacy, and the African colonies. He carried on a lively correspondence with royal relatives abroad, including Queen Victoria of England to whom he was related through his father.When his mother Queen Maria II died tragically at age 34 in childbirth, 16-year-old Pedro became regent. He ascended the throne at age 18 and was a model monarch. He ruled formally from 1855 to 1861, when he died of typhus. His brief but significant appearance as an enlightened ruler was a sad case of unfulfilled promise. -
85 Brown, Samuel
SUBJECT AREA: Steam and internal combustion engines[br]b. unknownd. 1849 England[br]English cooper, inventor of a gas vacuum engine.[br]Between the years 1823 and 1833, Brown achieved a number of a firsts as a pioneer of internal-combustion engines. In 1824 he built a full-scale working model of a pumping engine; in 1826, a vehicle fitted with a gas vacuum engine ascended Shooters Hill in Kent; and in 1827 he conducted trials of a motor-driven boat on the Thames that were witnessed by Lords of the Admiralty. The principle of Brown's engine had been demonstrated by Cecil in 1820. A burning gas flame was extinguished within a closed cylinder, creating a partial vacuum; atmospheric pressure was then utilized to produce the working stroke. By 1832 a number of Brown's engines in use for pumping water were reported, the most notable being at Croydon Canal. However, high fuel consumption and running costs prevented a wide acceptance of Brown's engines, and a company formed in 1825 was dissolved only two years later. Brown continued alone with his work until his death.[br]Bibliography1823, British patent no. 4,874 (gas vacuum engine).1826, British patent no. 5,350 (improved gas vacuum engine).1846, British patent no. 11,076, "Improvements in Gas Engines and in Propelling Carriages and Vessels" (no specification was enrolled).Further ReadingVarious discussions of Brown's engines can be found in Mechanics Magazine (1824) 2:360, 385; (1825) 3:6; (1825) 4:19, 309; (1826) 5:145; (1826) 6:79; (1827) 7:82–134; (1832) 17:273.The Engineer 182:214.A.K.Bruce, Samuel Brown and the Gas Engine.Dugald Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 2–3.KAB -
86 Charles, Jacques Alexandre César
SUBJECT AREA: Aerospace[br]b. 12 November 1746 Beaugency, Franced. 7 April 1823 Paris, France[br]French physicist who developed the first hydrogen balloon, in 1783.[br]In 1783, following the early experiments with small hot-air balloons by the Montgolfier brothers, there was a growing interest in the prospect of a balloon flight with people on board. The Paris Académie des Sciences encouraged one of their physicists, Charles, to carry out experiments and produce a balloon. Charles enlisted the assistance of two brothers, Anne-Jean and Marie-Noël Robert, who were practical craftsmen with experience of coating silk fabric with rubber to make it impermeable to gases. Charles decided to use the recently discovered lighter-than-air gas, hydrogen, for his experiments rather than hot air. After making several unmanned balloons, he had a manned balloon ready for testing on 1 December 1783. Despite the fact that a Montgolfier balloon had already flown with two passengers, there was enormous public interest in the flight: one estimate suggested that 400,000 people turned out to watch. Charles and Marie-Noël Robert ascended from the gardens of the Tuileries and landed after two hours, having covered 45 km (28 miles). Technically the "Charlière" was far superior to the "Montgolfière" and was therefore used by most subsequent balloonists until the introduction of the modern hot-air balloon by the American Paul E. Yost in the 1960s. Following Meusnier's proposals for a dirigible (steerable) balloon, put forward during 1783–5, Charles and the Robert brothers built an elongated balloon incorporating Meusnier's ballonnet principle. It had a rudder but the method of propulsion, by opening and closing parasols used as paddles, was totally ineffective.[br]Principal Honours and DistinctionsMember of the Académie des Sciences 1795.Further ReadingL.T.C.Rolt, 1966, The Aeronauts, London.

87 Fauvelle, Pierre-Pascal
SUBJECT AREA: Mining and extraction technology[br]b. 4 June 1797 Rethel, Ardennes, Franced. 19 December 1867 Perpignan, France[br]French inventor of hydraulic boring.[br]While attending the drilling of artesian wells in southern France in 1833, Fauvelle noticed that the debris from the borehole was carried out by the ascending water. This observation caused him to conceive the idea that the boring process need not necessarily be interrupted in order to clear the hole with an auger. It took him eleven years to develop his idea and to find financial backing to carry out his project in practice. In 1844, within a period of fifty-four days, he secretly bored an artesian well 219 m (718 ft) deep in Perpignan. One year later he secured his invention with a patent in France, and with another the following year in Spain.Fauvelle's process involved water being forced by a pressure pump through hollow rods to the bottom of the drill, whence it ascended through the annular space between the rod and the wall of the borehole, thus flushing the mud up to the surface. This method was similar to that of Robert Beart who had secured a patent in Britain but had not put it into practice. Although Fauvelle was not primarily concerned with the rotating action of the drill, his hydraulic boring method and its subsequent developments by his stepson, Alphonse de Basterot, formed an important step towards modern rotary drilling, which began with the work of Anthony F. Lucas near Beaumont, Texas, at the turn of the twentieth century. In the 1870s Albert Fauck, who also contributed important developments to the structure of boring rigs, had combined Fauvelle's hydraulic system with core-boring in the United States.[br]Bibliography1846, "Sur un nouveau système de forage", Comptes rendus de l'Académie des sciences, pp. 438–40; also printed in 1847 in Le Technologiste 8, pp. 87–8.Further ReadingA.Birembeaut, 1968, "Pierre-Pascal Fauvelle", Dictionnaire de biographie française, vol. 13, pp. 808–10; also in L'Indépendant, Perpignan, 5–10 February (biography).A.de Basterot, 1868, Puits artésiens, sondages de mines, sondages d'études, systèmeFauvelle et de Basterot, Brussels (a detailed description of Fauvelle's methods and de Basterot's developments).See also: Crælius, Per AntonWKBiographical history of technology > Fauvelle, Pierre-Pascal

88 Green, Charles
SUBJECT AREA: Aerospace[br]b. 31 January 1785 London, Englandd. 26 March 1870 London, England[br]English balloonist who introduced the use of coal gas for balloons.[br]Charles Green lived in London at a time when gas mains were being installed to supply coal gas for the recently introduced gas lighting. He was interested in the exploits of balloonists but lacked the finance needed to construct a balloon and fill it with expensive hydrogen. He decided to experiment with coal gas, which was very much cheaper, albeit a little heavier, than hydrogen: a larger balloon would be needed to lift the same weight. Green made his first ascent on 19 July 1821 to celebrate the coronation of King George. His large balloon was prepared in Green Park, London, and filled from the gas main in Piccadilly. He made a spectacular ascent to 11,000 ft (3,350 m), thus proving the suitability of coal gas, which was readily available and cheap. Like many balloonists, Green was also a showman. He made ascents on horseback or with fireworks to attract spectators. He did, however, try out some new ideas, such as cemented fabric joints (instead of stitching) for a huge new balloon, the Royal Vauxhall. On its first flight, in September 1836, this impressive balloon carried Green plus eight passengers. On 7 November 1836 Green and two friends ascended from Vauxhall Gardens, London, to make a long-distance flight. They landed safely in the Duchy of Nassau, Germany, having covered a record 480 miles (772 km) in eighteen hours. To help control the height of the balloon on this flight, Green fitted a long, heavy rope which trailed on the ground. If the balloon started to rise, then more of the "trail rope" was lifted off the ground, resulting in an increase in the weight to be lifted and a reduction in the rate of ascent. This idea had been suggested earlier by Thomas Baldwin in 1785, but Green developed it and in 1840 proposed to use if for a flight across the Atlantic: he later abandoned this plan.Charles Green made over five hundred ascents and died in bed at the age of 85, no small age for a balloonist.[br]Principal Honours and DistinctionsMember of the (Royal) Aeronautical Society, founded in 1866.Bibliography1836, Authentic Narrative of the Great Balloon Voyage and Descent in Germany, London (a pamphlet).Further ReadingL.T.C.Rolt, 1966, The Aeronauts, London (provides a full account of Green's achievements).J.E.Hodgson, 1924, the History of Aeronautics in Great Britain, London.T.Monck Mason, 1838, Aeronautica, London.JDS -
89 Montgolfier, Joseph-Michel
SUBJECT AREA: Aerospace[br]b. 26 August 1740 Vidalon-lès-Annonay, Franced. 26 June 1810 Balaruc-les-Bains, France[br]French ballooning pioneer who, with his brother Jacques-Etienne (b. 6 January 1745 Vidalon-lès-Annonay, France; d. 2 August 1799, Serriers, France), built the first balloon to carry passengers on a "free" flight.[br]Joseph-Michel and Jacques-Etienne Montgolfier were papermakers of Annonay, near Lyon. Joseph made the first experiments' after studying smoke rising from a fire and assuming that the smoke contained a gas which was lighter than air: of course, this lighter-than-air gas was just hot air. Using fine silk he made a small balloon with an aperture in its base, then, by burning paper beneath this aperture, he filled the balloon with hot air and it rose to the ceiling. Jacques-Etienne joined his brother in further experiments and they progressed to larger hot-air balloons until, by October 1783, they had constructed one large enough to lift two men on tethered ascents. In the same month Joseph-Michel delivered a paper at the University of Lyon on his experiments for a propulsive system by releasing gas through an opening in the side of a balloon; unfortunately, there was not enough pressurefor an effective jet. Then, on 21 November 1783, the scientist Pilâtre de Rozier and the Marquis d'Arlandes ascended on a "free" flight in a Montgolfier balloon. They departed from the grounds of a château in the Bois de Boulogne in Paris on what was to be the world's first aerial journey, covering 9 km (5/2 miles) in 25 minutes.Ballooning became a popular spectacle with initial rivalry between the hot-air Montgolfières and the hydrogen-filled Charlières of J.A.C. Charles. Interest in hot-air balloons subsided, but was revived in the 1960s by an American, Paul E. Yost. His propane-gas burner to provide hot-air was a great advance on the straw-burning fire-basket of the Montgolfiers.[br]Principal Honours and DistinctionsLégion d'honneur.Further ReadingC.C.Gillispie, 1983, The Montgolfier Brothers and the Invention of Aviation 1783–1784, Princeton, NJ (one of the publications to commemorate the bicentenary of the Montgolfiers).L.T.C.Rolt, 1966, The Aeronauts, London (describes the history of balloons).

90 Renard, Charles
SUBJECT AREA: Aerospace[br]b. 23 November 1847 Damblain, Vosges, Franced. 13 April 1905 Chalais-Meudon, France[br]French pioneer of military aeronautics who, with A.C.Krebs, built an airship powered by an electric motor.[br]Charles Renard was a French army officer with an interest in aviation. In 1873 he constructed an unusual unmanned glider with ten wings and an automatic stabilizing device to control rolling. This operated by means of a pendulum device linked to moving control surfaces. The model was launched from a tower near Arras, but unfortunately it spiralled into the ground. The control surfaces could not cope with the basic instability of the design, but as an idea for automatic flight control it was ahead of its time.Following a Commission report on the military use of balloons, carrier pigeons and an optical telegraph, an aeronautical establishment was set up in 1877 at Chalais-Meudon, near Paris, under the direction of Charles Renard, who was assisted by his brother Paul. The following year Renard and a colleague, Arthur Krebs, began to plan an airship. They received financial help from Léon Gambetta, a prominent politician who had escaped from Paris by balloon in 1870 during the siege by the Prussians. Renard and Krebs studied earlier airship designs: they used the outside shape of Paul Haenlein's gas-engined airship of 1872 and included Meusnier's internal air-filled ballonnets. The gas-engine had not been a success so they decided on an electric motor. Renard developed lightweight pile batteries while Krebs designed a motor, although this was later replaced by a more powerful Gramme motor of 6.5 kW (9 hp). La France was constructed at Chalais-Meudon and, after a two-month wait for calm conditions, the airship finally ascended on 9 August 1884. The motor was switched on and the flight began. Renard and Krebs found their airship handled well and after twenty-three minutes they landed back at their base. La, France made several successful flights, but its speed of only 24 km/h (15 mph) meant that flights could be made only in calm weather. Parts of La, France, including the electric motor, are preserved in the Musée de l'Air in Paris.Renard remained in charge of the establishment at Chalais-Meudon until his death. Among other things, he developed the "Train Renard", a train of articulated road vehicles for military and civil use, of which a number were built between 1903 and 1911. Towards the end of his life Renard became interested in helicopters, and in 1904 he built a large twin-rotor model which, however, failed to take off.[br]Bibliography1886, Le Ballon dirigeable La France, Paris (a description of the airship).Further ReadingDescriptions of Renard and Kreb's airship are given in most books on the history of lighter-than-air flight, e.g.L.T.C.Rolt, 1966, The Aeronauts, London; pub. in paperback 1985.C.Bailleux, c. 1988, Association pour l'Histoire de l'Electricité en France, (a detailed account of the conception and operations of La France).1977, Centenaire de la recherche aéronautique à Chalais-Meudon, Paris (an official memoir on the work of Chalais-Meudon with a chapter on Renard).JDS -
