Johann Ewald
Johann von Ewald (20 March 1744 – 25 June 1813) was a German army officer from Hesse-Kassel. After first serving in the Seven Years' War, he was the commander of the Jäger corps of the Hessian Leib Infantry Regiment attached to British forces in the American Revolutionary War. He arrived with his troops, first serving in the Battle of White Plains in October 1776. He saw regular action until his capture at Yorktown in 1781. In 1788, he joined the Danish Army, where he rose to the rank of lieutenant general; he also served as governor general of Holstein during the Napoleonic Wars. Following his American war experiences, he wrote an ''Essay on Partisan Warfare'' (), a widely read treatise on guerrilla warfare. He also kept a journal during most of his time in North America that has since become a valuable resource for historians of the war.

Victor Ewald
Victor Vladimirovich Ewald (27 November 1860 – 16 April 1935), was a Russian engineer, architect, and composer of music, mainly for conical brass instruments. Biography Victor Ewald was born in Saint Petersburg and died in Leningrad. Ewald was a professor of Civil Engineering in St. Petersburg, and was also the cellist with the Beliaeff Quartet for sixteen years. This quartet was the most influential ensemble in St. Petersburg in the late 19th century, introducing much of the standard quartet literature to Russian concertgoers. He also collected and published Russian folk songs much like other composers of his time. Ewald’s professional life, like that of many of his musical contemporaries, was in an entirely different field; that of a civil engineer. He excelled in this field, being appointed in 1900 as professor and manager of the Faculty of Construction Materials at the St. Petersburg Institute of Civil Engineers. From 1910 to 1924, Ewald served as editor of the archi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Ewald
Georg Heinrich August Ewald (16 November 1803 – 4 May 1875) was a German orientalist, Protestant theologian, and Biblical exegete. He studied at the University of Göttingen. In 1827 he became extraordinary professor there, in 1831 ordinary professor of theology, and in 1835 professor of oriental languages. In 1837, as a member of the Göttingen Seven, he lost his position at Göttingen on account of his protest against King Ernst August's abrogation of the liberal constitution, and became professor of theology at the University of Tübingen. In 1848, he returned to his old position at Göttingen. When Hanover was annexed by Prussia in 1866, Ewald became a defender of the rights of the ex-king. Among his chief works are: ''Complete Course on the Hebrew Language'' (), ''The Poetical Books of the Old Testament'' (), ''History of the People of Israel'' (), and ''Antiquities of the People of Israel'' (). Ewald represented the city of Hanover as a member of the Guelph faction in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Ewald
Johannes Ewald (18 November 174317 March 1781) was a Danish national dramatist, psalm writer and poet. The lyrics of a song from one of his plays are used for one of the Danish national anthems, ''Kong Christian stod ved højen mast'' which has equal status of national anthem together with '' Der er et yndigt land''. Quite until the days of romanticism, Ewald was considered the unsurpassed Danish poet. Today he is probably more lauded than read; though considered classics, only few of his works have become popular. Biography He was born in Copenhagen, Denmark. Ewald grew up in a strongly pietistic parsonage. His father was Enevold Ewald (1696-1754), vicar at the orphanage in Copenhagen. His maternal grandmother Marie Wulf (1685–1738), was a pietist and later a follower of the Moravian Church. He was fatherless from an early age. He was sent to school in the Duchy of Schleswig, his father's birthplace, and returned to enter the University of Copenhagen in 1758. At 15 he ...

Two Ewalds
The Two Ewalds (or Two Hewalds) were Saint Ewald the Black and Saint Ewald the White, martyrs in Old Saxony about 692. Both bore the same name, but were distinguished by the difference in the colour of their hair and complexions. They began their mission labours about 690 at the ancient Saxons country, now part of Westphalia, and covered by the dioceses of Münster, Osnabrück, and Paderborn. They are honored as saints in Westphalia. Background The two priests were companions, both natives of Northumbria, England. According to the example of many at that time, they spent several years as students in the schools of Ireland. Ewald the Black was the more learned of the two, but both were equally renowned for holiness of life. They were apparently acquainted with St. Willibrord, the Apostle of Friesland, and were animated with his zeal for the conversion of the Germans. Some sources number them among the eleven companions of that saint. More probably, however, they set out from Engla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ewald Summation
Ewald summation, named after Paul Peter Ewald, is a method for computing long-range interactions (e.g. electrostatic interactions) in periodic systems. It was first developed as the method for calculating the electrostatic energies of ionic crystals, and is now commonly used for calculating long-range interactions in computational chemistry. Ewald summation is a special case of the Poisson summation formula, replacing the summation of interaction energies in real space with an equivalent summation in Fourier space. In this method, the long-range interaction is divided into two parts: a short-range contribution, and a long-range contribution which does not have a singularity. The short-range contribution is calculated in real space, whereas the long-range contribution is calculated using a Fourier transform. The advantage of this method is the rapid convergence of the energy compared with that of a direct summation. This means that the method has high accuracy and reasonable spee ...
