Part 11

As a shire Hertfordshire is of purely military origin, being the district assigned to the fortress which Edward the Elder erected at Hertford. It is first mentioned in the Saxon Chronicle in 1011. At the time of the Domesday Survey the boundaries were approximately those of the present day, but part of Meppershall in Bedfordshire formed a detached portion of the shire and is still assessed for land and income tax in Hertfordshire. Of the nine Domesday hundreds, those of Danais and Tring were consolidated about 1200 under the name of Dacorum; the modern hundred of Cashio, from being held by the abbots of St Albans, was known as Albaneston, while the remaining six hundreds correspond approximately both in name and extent with those of the present day.

Hertfordshire was originally divided between the dioceses of London and Lincoln. In 1291 that part included in the Lincoln diocese formed part of the archdeaconry of Huntingdom and comprised the deaneries of Berkhampstead, Hitchin, Hertford and Baldock, and the archdeaconry and deanery of St Albans; while that part within the London diocese formed the deanery of Braughing within the archdeaconry of Middlesex. In 1535 the jurisdiction of St Albans had been transferred to the London diocese, the division being otherwise unchanged. In 1846 the whole county was placed within the diocese of Rochester and archdeaconry of St Albans, and in the next year the deaneries of Welwyn, Bennington, Buntingford, Bishop Stortford and Ware were created, and that of Braughing abolished. In 1864 the archdeaconries of Rochester and St Albans were united under the name of the archdeaconry of Rochester and St Albans. In 1878 the county was placed in the newly created diocese of St Albans, and formed the archdeaconry of St Albans, the deaneries being unchanged.

Hertfordshire was closely associated with Essex from the time of its first settlement, and the counties paid a joint fee-farm and were united under one sheriff until 1565, the shire-court being held at Hertford. The hundred of St Albans was at an early date constituted a separate liberty, with independent courts and coroners under the control of the abbot; it preserved a separate commission of the peace until 1874, when by act of parliament the county was arranged in two divisions, the eastern division being named Hertford, and the western the liberty of St Albans. These divisions have since been abolished.

Hertfordshire has always been an agricultural county, with few manufactures, and at the time of the Domesday Survey its wealth was derived almost entirely from its rural manors, with their water meadows, woodlands, fisheries paying rent in eels, and water-mills, the shire on its eastern side being noticeably free from waste land. In Norman times the woollen trade was considerable, and the great corn market at Royston has been famous since the reign of Elizabeth. At the time of the Civil War the malting industry was largely carried on, and saltpetre was produced in the county. In the 17th century Hertfordshire was famous for its horses, and the 18th century saw the introduction of several minor industries, such as straw-plaiting, paper-making and silk weaving.

In 1290 Hertfordshire returned two members to parliament, and in 1298 the borough of Hertford was represented. St Albans, Bishop Stortford and Berkhampstead acquired representation in the 14th century, but from 1375 to 1553 no returns were made for the boroughs. St Albans regained representation in 1553 and Hertford in 1623. Under the Reform Act of 1832 the county returned three members. St Albans was disfranchised on account of bribery in 1852. Hertford lost one member in 1868, and was disfranchised by the act of 1885.

_Antiquities._--Among the objects of antiquarian interest may be mentioned the cave of Royston, doubtless once used as a hermitage; Waltham Cross, erected to mark the spot where rested the body of Eleanor, queen of Edward I., on its way to Westminster for interment; and the Great Bed of Ware referred to in Shakespeare's _Twelfth Night_ and preserved at Rye House. The principal monastic buildings are the noble pile of St Albans abbey; the remains of Sopwell Benedictine nunnery near St Albans, founded in 1140; the remains of the priory of Ware, dedicated to St Francis, and originally a cell to the monastery of St Ebrulf at Utica in Normandy; and the remains of the priory at Hitchin built by Edward II. for the Carmelites. Among the more interesting churches may be mentioned those of Abbots Langley and Hemel Hempstead, both of Late Norman architecture; Baldock, a handsome mixed Gothic building supposed to have been erected by the Knights Templars in the reign of Stephen; Royston, formerly connected with the priory of canons regular; Hitchin of the 15th century; Hatfield, dating from the 13th century but in the main later; Berkhampstead, chiefly in the Perpendicular style, with a tower of the 16th century. Sandridge church shows good Norman work with the use of Roman bricks; Wheathampstead church, mainly very fine Decorated, has pre-Norman remains. The remains of secular buildings of importance are those of Berkhampstead castle, Hertford castle, Hatfield palace of the bishops of Ely, the slight traces at Bishop Stortford, and the earthworks at Anstey. Among the numerous mansions of interest, Rye House, erected in the reign of Henry VI., was tenanted by Rumbold, one of the principal agents in the plot to assassinate Charles II. Moor Park, Rickmansworth, once the property of St Albans abbey, was granted by Henry VII. to John de Vere, earl of Oxford, and was afterwards the property of the duke of Monmouth, who built the present mansion, which, however, was subsequently cased with Portland stone and received various other additions. Knebworth, the seat of the Lyttons, was originally a Norman fortress, rebuilt in the time of Elizabeth in the Tudor style and restored in the 19th century. Hatfield House is the seat of the marquis of Salisbury; but its earlier history is of great interest, as is that of Theobalds near Cheshunt. Panshanger House, until recently the principal seat of the Cowpers, is a splendid mansion in Gothic style erected at the beginning of the 19th century. The manor of Cashiobury House, the seat of the earls of Essex, was formerly held by the abbot of St Albans, but the mansion was rebuilt in the beginning of the 19th century from designs by Wyatt. Gorhambury House, near St Albans, the seat of the earl of Verulam, formerly the seat of the Bacons, and the residence of the great chancellor, was rebuilt at the close of the 18th century. At Kings Langley and Hunsdon were also former royal residences.

HERTHA, or NERTHUS, in Teutonic mythology, the goddess of fertility, "Mother Earth." Tacitus states that many Teutonic tribes worshipped her with orgies and mysterious rites celebrated at night. The chief seat of her cult was an island which has not been identified. A single priest performed the service. Her veiled statue was moved from place to place by sacred cows on which none but the priest might lay hands. At the conclusion of the rites the image, its vestments and its vehicle were bathed in a lake.

HERTZ, HEINRICH RUDOLF (1857-1894), German physicist, was born at Hamburg on the 22nd of February 1857. On leaving school he determined to adopt the profession of engineering, and in the pursuance of this decision went to study in Munich in 1877. But soon coming to the conclusion that engineering was not his vocation he abandoned it in favour of physical science, and in October 1878 began to attend the lectures of G. R. Kirchhoff and H. von Helmholtz at Berlin. In preparation for these he spent the winter of 1877-1878 in reading up original treatises like those of Laplace and Lagrange on mathematics and mechanics, and in attending courses on practical physics under P. G. von Jolly and J. F. W. von Bezold; the consequence was that within a few days of his arrival in Berlin in October 1878 he was able to plunge into original research on a problem of electric inertia. For the best solution a prize was offered by the philosophical faculty of the University, and this he succeeded in winning with the paper which was published in 1880 on the "Kinetic Energy of Electricity in Motion." His next investigation, on "Induction in Rotating Spheres," he offered in 1880 as his dissertation for his doctor's degree, which he obtained with the rare distinction of _summa cum laude_. Later in the same year he became assistant to Helmholtz in the physical laboratory of the Berlin Institute. During the three years he held this position he carried out researches on the contact of elastic solids, hardness, evaporation and the electric discharge in gases, the last earning him the special commendation of Helmholtz. In 1883 he went to Kiel, becoming _Privatdozent_, and there he began the studies in Maxwell's electromagnetic theory which a few years later resulted in the discoveries that rendered his name famous. These were actually made between 1885 and 1889, when he was professor of physics in the Carlsruhe Polytechnic. He himself recorded that their origin is to be sought in a prize problem proposed by the Berlin Academy of Sciences in 1879, having reference to the experimental establishment of some relation between electromagnetic forces and the dielectric polarization of insulators. Imagining that this would interest Hertz and be successfully attacked by him, Helmholtz specially drew his attention to it, and promised him the assistance of the Institute if he decided to work on the subject; but Hertz did not take it up seriously at that time, because he could not think of any procedure likely to prove effective. It was of course well known, as a necessity of Maxwell's mathematical theory, that the polarization and depolarization of an insulator must give rise to the same electromagnetic effects in the neighbourhood as a voltaic current in a conductor. The experimental proof, however, was still lacking, and though several experimenters had come very near its discovery, Hertz was the first who actually succeeded in supplying it, in 1887. Continuing his inquiries for the next year or two, he was able to discover the progressive propagation of electromagnetic action through space, to measure the length and velocity of electromagnetic waves, and to show that in the transverse nature of their vibration and their susceptibility to reflection, refraction and polarization they are in complete correspondence with the waves of light and heat. The result, was in Helmholtz's words, to establish beyond doubt that ordinary light consists of electrical vibrations in an all-pervading ether which possesses the properties of an insulator and of a magnetic medium. Hertz himself gave an admirable account of the significance of his discoveries in a lecture on the relations between light and electricity, delivered before the German Society for the Advancement of Natural Science and Medicine at Heidelberg in September 1889. Since the time of these early experiments, various other modes of detecting the existence of electric waves have been found out in addition to the spark-gap which he first employed, and the results of his observations, the earliest interest of which was simply that they afforded a confirmation of an abstruse mathematical theory, have been applied to the practical purposes of signalling over considerable distances (see TELEGRAPHY, WIRELESS). In 1889 Hertz was appointed to succeed R. J. E. Clausius as ordinary professor of physics in the university of Bonn. There he continued his researches on the discharge of electricity in rarefied gases, only just missing the discovery of the X-rays described by W. C. Rontgen a few years later, and produced his treatise on the _Principles of Mechanics_. This was his last work, for after a long illness he died at Bonn on the 1st of January 1894. By his premature death science lost one of her most promising disciples. Helmholtz thought him the one of all his pupils who had penetrated farthest into his own circle of scientific thought, and looked to him with the greatest confidence for the further extension and development of his work.

Hertz's scientific papers were translated into English by Professor D. E. Jones, and published in three volumes: _Electric Waves_ (1893), _Miscellaneous Papers_ (1896), and _Principles of Mechanics_ (1899). The preface contributed to the first of these by Lord Kelvin, and the introductions to the second and third by Professors P. E. A. Lenard and Helmholtz, contain many biographical details, together with statements of the scope and significance of his investigations.

HERTZ, HENRIK (1797-1870), Danish poet, was born of Jewish parents in Copenhagen on the 25th of August 1798. In 1817 he was sent to the university. His father died in his infancy, and the family property was destroyed in the bombardment of 1807. The boy was brought up by his relative, M. L. Nathanson, a well-known newspaper editor. Young Hertz passed his examination in law in 1825. But his taste was all for polite literature, and in 1826-1827 two plays of his were produced, _Mr Burchardt and his Family_ and _Love and Policy_; in 1828 followed the comedy of _Flyttedagen_. In 1830 he brought out what was a complete novelty in Danish literature, a comedy in rhymed verse, _Amor's Strokes of Genius_. In the same year Hertz published anonymously _Gengangerbrevene_, or Letters from a Ghost, which he pretended were written by Baggesen, who had died in 1826. The book was written in defence of J. L. Heiberg, and was full of satirical humour and fine critical insight. Its success was overwhelming; but Hertz preserved his anonymity, and the secret was not known until many years later. In 1832 he published a didactic poem, _Nature and Art_, and _Four Poetical Epistles_. _A Day on the Island of Als_ was his next comedy, followed in 1835 by _The Only Fault_. Hertz passed through Germany and Switzerland into Italy in 1833; he spent the winter there, and returned the following autumn through France to Denmark. In 1836 his comedy of _The Savings Bank_ enjoyed a great success. But it was not till 1837 that he gave the full measure of his genius in the romantic national drama of _Svend Dyrings Hus_, a beautiful and original piece. His historical tragedy _Valdemar Atterdag_ was not so well received in 1839; but in 1845 he achieved an immense success with his lyrical drama _Kong Rene's Datter_ (King Rene's Daughter), which has been translated into almost every European language. To this succeeded the tragedy of _Ninon_ in 1848, the romantic comedy of _Tonietta_ in 1849, _A Sacrifice_ in 1853, _The Youngest_ in 1854. His lyrical poems appeared in successive collections, dated 1832, 1840 and 1844. From 1858 to 1859 he edited a literary journal entitled _Weekly Leaves_. His last drama, _Three Days in Padua_, was produced in 1869, and he died on the 25th of February of the next year.

Hertz is one of the first of Danish lyrical poets. His poems are full of colour and passion, his versification has more witchcraft in it than any other poet's of his age, and his style is grace itself. He has all the sensuous fire of Keats without his proclivity to the antique. As a romantic dramatist he is scarcely less original. He has bequeathed to the Danish theatre, in _Svend Dyrings Hus_ and _King Rene's Daughter_, two pieces which have become classic. He is a troubadour by instinct; he has little or nothing of Scandinavian local colouring, and succeeds best when he is describing the scenery or the emotions of the glowing south.

His _Dramatic Works_ (18 vols.) were published at Copenhagen in 1854-1873; and his _Poems_ (4 vols.) in 1851-1862.

HERTZBERG, EWALD FRIEDRICH, COUNT VON (1725-1795), Prussian statesman, who came of a noble family which had been settled in Pomerania since the 13th century, was born at Lottin, in that province, on the 2nd of September 1725. After 1739 he studied, chiefly classics and history at the gymnasium at Stettin, and in 1742 entered the university of Halle as a student of jurisprudence, becoming in due course a doctor of laws in 1745. In addition to this principal study, he was also interested while at the university in historical and philosophical (Christian Wolff) studies. A first thesis for his doctorate, entitled _Jus publicum Brandenburgicum_, was not printed, because it contained a criticism of the existing condition of the state. Shortly afterwards Hertzberg entered the government service, in which he was first employed in the department of the state archives (of which he became director in 1750), soon after in the foreign office, and finally in 1763 as chief minister (_Cabinetsminister_). In 1752 he married Baroness Marie von Knyphausen, a marriage which was happy, but childless.

For more than forty years Hertzberg played an active part in the Prussian foreign office. In this capacity he had a decisive influence on Prussian policy, both under Frederick the Great and Frederick William II. At the beginning of the Seven Years' War (1756) he took part as a political writer in the Hohenzollern-Habsburg quarrel, both in his _Ursachen, die S.K.M. in Preussen bewogen haben, sich wider die Absichten des Wienerischen Hofes zu setzen und deren Ausfuhrung zuvorzukommen_ ("Motives which have induced the king of Prussia to oppose the intentions of the court of Vienna, and to prevent them from being carried into effect"), and in his _Memoire raisonne sur la conduite des cours de Vienne et de Saxe_, based on the secret papers taken by Frederick the Great from the archives of Dresden. After the defeat at Kolin (1757) he hastened to Pomerania in order to organize the national defence there and collect the necessary troops for the protection of the fortresses of Stettin and Colberg. In the same year he conducted the peace negotiations with Sweden, and was of great service in bringing about the peace of Hubertsburg (1763), on the conclusion of which the king received him with the words, "I congratulate you. You have made peace as I made war, one against many."

In the later years, too, of Frederick the Great's reign, Hertzberg played a considerable part in foreign policy. In 1772, in a memoir based upon comprehensive historical studies, he defended the Prussian claims to certain provinces of Poland. He also took part successfully as a publicist in the negotiations concerning the question of the Bavarian succession (1778) and those of the peace of Teschen (1779). But in 1780 he failed to uphold Prussian interests at the election of the bishop of Munster. In 1784 appeared Hertzberg's memoir containing a thorough study of the _Furstenbund_. He championed this latest creation of Frederick the Great's mainly with a view to an energetic reform of the empire, though the idea of German unity was naturally still far from his mind. In 1785 followed "An explanation of the motives which have led the king of Prussia to propose to the other high estates of the empire an association for the maintenance of the system of the empire" (_Erklarung der Ursachen, welche S.M. in Preussen bewogen haben, ihren hohen Mitstanden des Reichs eine Association zur Erhaltung des Reichssystems anzutragen_). By upholding the Furstenbund Hertzberg made many enemies, prominent among whom was the king's brother, Prince Henry. Though the _Furstenbund_ failed to effect a reform of the empire, it at any rate prevented the fulfilment of Joseph II.'s old desire for the incorporation of Bavaria with Austria. The last act of state in which Hertzberg took part under Frederick the Great was the commercial treaty concluded in 1785 between Prussia and the United States.

With Frederick, especially in his later years, Hertzberg stood in very intimate personal relations and was often the king's guest at Sans-Souci. Under Frederick William II. his influential position at the court of Berlin was at first unshaken. The king at once received him with favour, as is clearly proved by Hertzberg's elevation to the rank of count in 1786; and Mirabeau would never have attacked him with such violence in his _Secret History of the Court of Berlin_, which appeared in 1788, if he had not seen in him the most powerful man after the king. In this attack Mirabeau seems to have been influenced by Hertzberg's personal enemies at the court. Hertzberg's political system remained on the whole the same under Frederick William II. as it had been under his predecessor. It was mainly characterized by a sharp opposition to the house of Habsburg and by a desire to win for Prussia the support of England, a policy supported by him in important memoirs of the years 1786 and 1787. His diplomacy was directed also against Austria's old ally, France. Hence it was chiefly owing to Hertzberg that in 1787, in spite of the king's unwillingness at first, Prussia intervened in Holland in support of the stadtholder William V. against the democratic French party (see HOLLAND: _History_). The success of this intervention, which was the practical realization of a plan very characteristic of Hertzberg, marks the culminating point in his career.

But the opposition between him and the new king, which had already appeared at the time of the conclusion of the triple alliance between Holland, England and Prussia, became more marked in the following years, when Hertzberg, relying upon this alliance, and in conscious imitation of Frederick II.'s policy at the time of the first partition of Poland, sought to take advantage of the entanglement of Austria with Russia in the war with Turkey to secure for Prussia an extension of territory by diplomatic intervention. According to his plan, Prussia was to offer her mediation at the proper moment, and in the territorial readjustments that the peace would bring, was to receive Danzig and Thorn as her portion. Beyond this he aimed at preventing the restoration of the hegemony of Austria in the Empire, and secretly cherished the hope of restoring Frederick the Great's Russian alliance.

With a curious obstinacy he continued to pursue these aims even when, owing to military and diplomatic events, they were already partly out of date. His personal position became increasingly difficult, as deep-rooted differences between him and the king were revealed during these diplomatic campaigns. Hertzberg wished to effect everything by peaceful means, while Frederick William II. was for a time determined on war with Austria. As regards Polish policy, too, their ideas came into conflict, Hertzberg having always been openly opposed to the total annihilation of the Polish kingdom. The same is true of the attitude of king and minister towards Great Britain. At the conferences at Reichenbach in the summer of 1790, this opposition became more and more acute, and Hertzberg was only with difficulty persuaded to come to an agreement merely on the basis of the _status_ quo, as demanded by Pitt. The king's renunciation of any extension of territory was in Hertzberg's eyes impolitic, and this view of his was later endorsed by Bismarck. A letter which came to the eyes of the king, in which Hertzberg severely criticized the king's foreign policy, and especially his plans for attacking Russia, led to his dismissal on the 5th of July 1791. He afterwards made several attempts to exert an influence over foreign affairs, but in vain. The king showed himself more and more personally hostile to the ex-minister, and in later years pursued Hertzberg, now quite embittered, with every kind of petty persecution, even ordering his letters to be opened.
