101 Stevens, Robert Livingston
SUBJECT AREA: Ports and shipping[br]b. 18 October 1787 Hoboken, New Jersey, USAd. 20 April 1856 Hoboken, New Jersey, USA[br]American engineer, pioneer of steamboats and railways.[br]R.L.Stevens was the son of John Stevens and was given the technical education his father lacked. He assisted his father with the Little Juliana and the Phoenix, managed the commercial operation of the Phoenix on the Delaware River, and subsequently built many other steamboats.In 1830 he and his brother Edwin A.Stevens obtained a charter from the New Jersey Legislature for the Camden \& Amboy Railroad \& Transportation Company, and he visited Britain to obtain rails and a locomotive. Railway track in the USA then normally comprised longitudinal timber rails with running surfaces of iron straps, but Stevens designed rails of flat-bottom section, which were to become standard, and had the first batch rolled in Wales. He also designed hookheaded spikes for them, and "iron tongues", which became fishplates. From Robert Stephenson \& Co. (see Robert Stephenson) he obtained the locomotive John Bull, which was similar to the Liverpool \& Manchester Railway's Samson. The Camden \& Amboy Railroad was opened in 1831, but John Bull, a 0–4–0, proved over sensitive to imperfections in the track; Stevens and his mechanic, Isaac Dripps, added a two-wheeled non-swivelling "pilot" at the front to guide it round curves. The locomotive survives at the Smithsonian Institution, Washington, DC.[br]Further ReadingH.P.Spratt, 1958, The Birth of the Steamboat, Charles Griffin.J.H.White Jr, 1979, A History of the American Locomotive—Its Development: 1830– 1880, New York: Dover Publications Inc.J.F.Stover, 1961, American Railroads, Chicago: University of Chicago Press.PJGRBiographical history of technology > Stevens, Robert Livingston

102 Thévénin, Léon Charles
SUBJECT AREA: Electricity[br]b. 30 March 1857 Paris, Franced. 21 September 1926 Paris, France[br]French telegraph engineer who extended Ohm's Law to the analysis of complex electrical circuits.[br]Following a basic education, Thévénin entered the Ecole Polytechnique in Paris, graduating in 1876. In 1878 he joined the Corps of Telegraph Engineers (which subsequently became the French PTT). There he initially worked on the development of long-distance underground telegraph lines, but he later switched to working on power lines. Appointed a teaching inspector at the Ecole Supérieure in 1882, he became increasingly interested in the problems of measurement in electrical circuits. As a result of studying Kirchoff's Laws, which were essentially derived from Ohm's Law, he developed his now-famous theorem which made it possible to calculate the currents in more complex electrical circuits.As well as becoming Head of the Bureau des Lignes, up until his death he also found time for teaching other subjects outside the Ecole, including a course in mechanics at the Institut National Agronomique. In 1896 he was appointed Director of the Telegraph Engineering School, then, in 1901, Engineer-in-Chief of the telegraph workshops. He retired in 1914.[br]Bibliography1883, "Extension of Ohm's Law to complex electrical circuits", Comptes rendus 97:159 (describes Thévénin's Theorem).Further ReadingF.E.Terman, 1943, Radio Engineers'Handbook, New York: McGraw-Hill, Section 3 (summarizes the relevant circuit theory).KF -
103 Watson-Watt, Sir Robert Alexander
[br]b. 13 April 1892 Brechin, Angus, Scotlandd. 6 December 1973 Inverness, Scotland[br]Scottish engineer and scientific adviser known for his work on radar.[br]Following education at Brechin High School, Watson-Watt entered University College, Dundee (then a part of the University of St Andrews), obtaining a BSc in engineering in 1912. From 1912 until 1921 he was Assistant to the Professor of Natural Philosophy at St Andrews, but during the First World War he also held various posts in the Meteorological Office. During. this time, in 1916 he proposed the use of cathode ray oscillographs for radio-direction-finding displays. He joined the newly formed Radio Research Station at Slough when it was opened in 1924, and 3 years later, when it amalgamated with the Radio Section of the National Physical Laboratory, he became Superintendent at Slough. At this time he proposed the name "ionosphere" for the ionized layer in the upper atmosphere. With E.V. Appleton and J.F.Herd he developed the "squegger" hard-valve transformer-coupled timebase and with the latter devised a direction-finding radio-goniometer.In 1933 he was asked to investigate possible aircraft counter-measures. He soon showed that it was impossible to make the wished-for radio "death-ray", but had the idea of using the detection of reflected radio-waves as a means of monitoring the approach of enemy aircraft. With six assistants he developed this idea and constructed an experimental system of radar (RAdio Detection And Ranging) in which arrays of aerials were used to detect the reflected signals and deduce the bearing and height. To realize a practical system, in September 1936 he was appointed Director of the Bawdsey Research Station near Felixstowe and carried out operational studies of radar. The result was that within two years the East Coast of the British Isles was equipped with a network of radar transmitters and receivers working in the 7–14 metre band—the so-called "chain-home" system—which did so much to assist the efficient deployment of RAF Fighter Command against German bombing raids on Britain in the early years of the Second World War.In 1938 he moved to the Air Ministry as Director of Communications Development, becoming Scientific Adviser to the Air Ministry and Ministry of Aircraft Production in 1940, then Deputy Chairman of the War Cabinet Radio Board in 1943. After the war he set up Sir Robert Watson-Watt \& Partners, an industrial consultant firm. He then spent some years in relative retirement in Canada, but returned to Scotland before his death.[br]Principal Honours and DistinctionsKnighted 1942. CBE 1941. FRS 1941. US Medal of Merit 1946.

104 πρεσβύτερος
πρεσβύτερος, α, ον (Hom.+; comp. of πρέσβυς)① pert. to being relatively advanced in age, older, oldⓐ of an individual person older of two ὁ υἱὸς ὁ πρ. (cp. Aelian, VH 9, 42; TestJob 15:2 τῷ ἀδελφῷ τῷ πρεσβυτέρῳ; JosAs; Just., A II, 6, 1) Lk 15:25; of Manasseh (w. Ephraim) B 13:5. In contrast to the younger generation οἱ πρεσβύτεροι the older ones J 8:9. Opp. οἱ νεανίσκοι Ac 2:17 (Jo 3:1). Opp. νεώτεροι (s. νεός 3aβ) 1 Ti 5:1 (similar advice, containing a contrast betw. πρ. and νεώτ., from ins and lit. in MDibelius, Hdb. ad loc.); 1 Pt 5:5 (though here the πρεσβύτεροι are not only the older people, but at the same time, the ‘elders’; s. 2bβ). The same double mng. is found for πρεσβύτεροι in 1 Cl 1:3 beside νέοι, while in 3:3; 21:6, beside the same word, the concept of being old is the dominant one (as Jos., C. Ap. 2, 206). On the disputed pass. Hv 3, 1, 8 (οἱ νεανίσκοι … οἱ πρεσβύτεροι) cp. MDibelius, Hdb. ad loc.—Fem. πρεσβυτέρα old(er) woman (opp. νεωτέρα, as Gen 19:31) 1 Ti 5:2.—With no ref. to younger persons, w. complete disappearance of the comparative aspect: πρεσβύτερος an old man (Jos., Ant. 13, 226; 292 [as a witness of events in the past, as Ps.-Pla., Virt. 3, 377b; 4, 377c]) Hv 3, 12, 2; cp. 3, 11, 3. The personified church is called λίαν πρεσβυτέρα very old 3, 10, 3; cp. 3, 11, 2. She appears as ἡ πρ. the elderly woman 2, 1, 3; 3, 1, 2; 3, 10, 6; 9 and has τὰς τρίχας πρεσβυτέρας the hair of an old woman 3, 10, 4; 5; 3, 12, 1.ⓑ of a period of time (Petosiris, Fgm. 3 and 4 mention οἱ πρεσβύτεροι and οἱ νεώτεροι. In both instances the context shows that the reference is to astrologers from earlier and more recent times) οἱ πρεσβύτεροι the men of old, our ancestors Hb 11:2. ἡ παράδοσις τῶν πρεσβυτέρων the tradition of the ancients (cp. Iambl., Vi. Pyth. 35, 253 τῶν π. συγγράμματα) Mt 15:2; Mk 7:3, 5 (ELohse, D. Ordination im Spätjudentum u. NT, ’51, 50–56: scholars).② an official (cp. Lat. senator), elder, presbyterⓐ among the Jews (the congregation of a synagogue in Jerusalem used πρεσβύτεροι to denote its officers before 70 A.D.: SEG VIII, 170, 9; cp. Dssm., LO 378–80 [LAE 439–41]).α. for members of local councils in individual cities (cp. Josh 20:4; Ruth 4:2; 2 Esdr 10:14; Jdth 8:10; 10:6) Lk 7:3; 1 Cl 55:4.—Schürer II, 185.β. for members of a group in the Sanhedrin (Schürer II, 206–8; JJeremias, Jerusalem z. Zt. Jesu II B 1: Die gesellschaftl. Oberschicht 1929, 88ff). They are mentioned together w. (the) other groups: ἀρχιερεῖς (Ac 4:5 has ἄρχοντες for this), γραμματεῖς, πρεσβύτεροι (the order is not always the same) Mt 16:21; 26:3 v.l.; 27:41; Mk 8:31; 11:27; 14:43, 53; 15:1; Lk 9:22; 20:1.—Only ἀρχιερεῖς (Ac 4:8 has for this ἄρχοντες τοῦ λαοῦ) and πρεσβύτεροι (τοῦ λαοῦ: cp. Ex 19:7; Num 11:16b, 24; 1 Macc 7:33; 12:35; Just., D. 40, 4 al.) Mt 21:23; 26:3, 47, 59 v.l.; 27:1, 3, 12, 20; 28:(11), 12; Lk 22:52 (here, as an exception, οἱ στρατηγοὶ τοῦ ἱεροῦ); Ac 4:23; 23:14; 25:15; cp. 24:1. Also οἱ πρεσβύτεροι καὶ οἱ ἱερεῖς GPt 7:25 (for this combination cp. Jos., Ant. 11, 83; 12, 406).—Only πρεσβύτεροι and γραμματεῖς Mt 26:57; Ac 6:12.—The use of πρεσβύτερος as a title among the Jews of the Diaspora appears quite late, except for the allusions in the LXX (cp. Schürer III/1, 102; MAMA III [Cilicia], 344; 448 [cp. ZNW 31, ’32, 313f]. Whether πρεσβύτερος is to be understood in the older Roman inscriptions [CIJ 378] as a title [so CIJ p. lxxxvi], remains doubtful).ⓑ among the Christians (for their use of the word as a title one must bear in mind not only the Jewish custom, but also its use as a t.t. among the ἔθνη, in connection w. associations of the ‘old ones’ [FPoland, Geschichte des griech. Vereinswesens 1909, 98ff] and to designate civic as well as religious officials [Dssm., B 153ff=BS 154–57, NB 60ff=BS 233–35, also LO 315, 5; HHausschildt, ZNW 4, 1903, 235ff; MStrack, ibid. 213ff; HLietzmann, ZWT 55, 1914, 116–32 [=Kl. Schr. I ’58, 156–69]; MDibelius, exc. on 1 Ti 5:17ff; RAlastair-Campbell, The Elders, Seniority within Earliest Christianity ’94.].—BGU 16, 6 [159 A.D.] πρεσβύτεροι ἱερεῖς θεοῦ Σοκνοπαίου; 347, 6; PVindBosw 1, 31 [87 A.D.].—As honorary title: Iren. 4, 26, 5 [Harv. II 238, 3]. The Engl. word ‘priest’ comes fr. πρεσβύτερος via Lat. presbyter; later Christian usage is largely, if not entirely, responsible for this development; s. OED s.v. ‘priest’ B).α. Ac 11:30; 14:23; 15:2, 4, 6, 22f; 16:4 (in all the places in Ac 15 and 16 mention is made of οἱ ἀπόστολοι καὶ οἱ πρεσβύτεροι in the Jerusalem church); 20:17; 21:18; 1 Ti 5:17, 19 (Nicol. Dam.: 90 Fgm. 103a Jac. νεωτέρῳ πρεσβυτέρου καταμαρτυρεῖν οὐκ ἔξεστι); Tit 1:5; Js 5:14; 1 Pt 5:1, 5 (s. 1a above); 1 Cl 44:5; 47:6; 54:2; 57:1. WWrede, Untersuchungen zum 1 Cl 1891, 8ff.—Acc. to 2 Cl 17:3, 5 exhortation and preaching in the church services were among their duties.—In Ign. the πρεσβύτεροι come after the bishop, to whom they are subordinate IMg 2; 3:1; 6:1, or betw. the bishop and the deacons IPhld inscr.; 10:2; IPol 6:1, or the higher rank of the bishop in comparison to them is made plain in some other way ITr 3:1; 12:2 (s. πρεσβυτέριον b; cp. Hippol., Ref. 9, 12, 22).—Polycarp—an ἐπίσκοπος, accord. to the title of the Ep. bearing his name—groups himself w. πρεσβύτεροι in Pol inscr., and further takes the presence of presbyters in Philippi for granted (beside deacons, though no ἐπίσκοπος is mentioned; cp. Hdb. on Pol inscr.) Pol 5:3.β. Just how we are to understand the words ὁ πρεσβύτερος, applied to himself by the author of the two smallest Johannine letters 2J 1; 3J 1, remains in doubt. But in any case it is meant to indicate a position of great dignity the elder.—HWindisch, exc. on 3J, end; ESchwartz, Über den Tod der Söhne Zebedaei 1904, 47; 51; HWendt, ZNW 23, 1924, 19; EKäsemann, ZTK 48, ’51, 292–311; DWatson, NTS 35, ’89, 104–30, rhetorical analysis of 2J.—ὁ πρ. and οἱ πρ. are mentioned by Papias in these much-discussed passages: 2:3, 4, 5, 7, 14, 15. For some of the lit. s. the note on JKleist’s transl. ’48, p. 207 n. 18.γ. In Rv there are 24 elders sitting on thrones about the throne of God; they form a heavenly council of elders (cp. Is 24:23) 4:4, 10; 5:5–14; 7:11, 13; 11:16; 14:3; 19:4. The elders have been understood as glorified human beings of some kind or astral deities (or angels) (for the var. views s. RCharles, ICC Rv I 128–33; JMichl, D. 24 Ältesten in d. Apk. d. hl. J. ’38); the number 24 has been referred to the following: the 24 priestly classes of the Jews (1 Ch 24:7–18; Jos., Ant. 7, 365–67) whose heads were called ‘elders’ (Yoma 1, 5; Tamid 1, 1; Middoth 1, 8); the 24 stars which, according to Babylonian belief, stood half on the north and half on the south of the zodiac (Diod S 2, 31, 4; POsl 4, 19: HGunkel, Z. religionsgesch. Verständnis des NT 1903, 42f; Boll 35f); the 24 hours of the day, represented as old men w. shining garments and w. crowns (acc. to the Test. of Adam [ed. CBezold, TNöldeke Festschr. 1906, 893–912]: JWellhausen, Analyse der Offb. Joh. 1907, p. 9, 1; NMorosof, Offb. Joh. 1912, 32); the 24 Yazatas in the state of the gods in heaven, acc. to Persian thought (Bousset). It is certainly an open question whether, or how far, the writer of Rv had any of these things in mind.—On the presbyters, and esp. on the question how ἐπίσκοπος and πρεσβύτερος were originally related to each other (a question which is raised particularly in the pastorals; cp. MDibelius, Hdb. exc. after 1 Ti 3:7 section 2 [w. lit.] and before 5:17), s. the lit. s.v. ἐπίσκοπος.—BEaston, Pastoral Epistles ’47, 188–97; WMichaelis, Das Ältestenamt ’53; GBornkamm, πρεσβύτερος; RCampbell, The Elders ’94.—B. 1472.
