IN: Robert Owen (; 14 May 1771 - 17 November 1858) was a Welsh textile manufacturer, philanthropic social reformer, and one of the founders of utopian socialism and the cooperative movement. Owen is best known for his efforts to improve the working conditions of his factory workers and his promotion of experimental socialistic communities.

Although Owen made brief visits to the United States, London became his permanent home and the centre of his activities in 1828. After an extended period of friction with William Allen and some of his other business partners, Owen relinquished all of connections to New Lanark. He is often quoted as comment Allen at the time, "All the world is queer save thee and me, and even thou art a little queer". Having invested most of his personal fortune in the failed New Harmony communal experiment, Owen was no longer a wealthy capitalist; however, he remained the head of a vigorous propaganda effort to promote industrial equality, free education for children, and adequate living conditions in factory towns. In addition, he delivered lectures in Europe and published a weekly newspaper to gain support for his ideas. In 1832 Owen opened the National Equitable Labour Exchange system, a time-based currency in which the exchange of goods was effected by means of labour notes; this system superseded the usual means of exchange and middlemen. The London exchange continued until 1833; a Birmingham branch operated for only a few months until July 1833. Owen also became involved in trade unionism. He briefly served as the leader of the Grand National Consolidated Trade Union (GNCTU) before its collapse in 1834. Socialism first became current in British terminology in the discussions of the Association of all Classes of all Nations, which Owen formed in 1835 and served as its initial leader. Owen's secular views also gained enough influence among the working classes to cause the Westminster Review to comment in 1839 that his principles were the actual creed of a great portion of them. However, by 1846, the only long-lasting result of Owen's agitation for social change, carried on through public meetings, pamphlets, periodicals, and occasional treatises, remained the co-operative movement, and for a time even that seemed to have utterly collapsed.

did he teach or lecture people

Answer the question at the end by quoting:

Timur was born in Transoxiana near the city of Kesh (modern Shahrisabz, Uzbekistan) some 80 kilometres (50 mi) south of Samarkand, part of what was then the Chagatai Khanate. His father, Taraqai, was a minor noble of the Barlas, a Mongolian tribe that had been turkified in many aspects. According to Gerard Chaliand, Timur was a Muslim, and he saw himself as Genghis Khan's heir. Though not a Borjigid or a descendent of Genghis Khan, he clearly sought to invoke the legacy of Genghis Khan's conquests during his lifetime.
It was in this period that Timur reduced the Chagatai khans to the position of figureheads while he ruled in their name. Also during this period, Timur and his brother-in-law Husayn, who were at first fellow fugitives and wanderers in joint adventures, became rivals and antagonists. The relationship between them began to become strained after Husayn abandoned efforts to carry out Timur's orders to finish off Ilya Khoja (former governor of Mawarannah) close to Tishnet. Timur began to gain a following of people in Balkh, consisting of merchants, fellow tribesmen, Muslim clergy, aristocracy and agricultural workers, because of his kindness in sharing his belongings with them. This contrasted Timur's behavior with that of Husayn, who alienated these people, took many possessions from them via his heavy tax laws and selfishly spent the tax money building elaborate structures. At around 1370 Husayn surrendered to Timur and was later assassinated, which allowed Timur to be formally proclaimed sovereign at Balkh. He married Husayn's wife Saray Mulk Khanum, a descendant of Genghis Khan, allowing him to become imperial ruler of the Chaghatay tribe. One day Aksak Temur spoke thusly: "Khan Zudei (in China) rules over the city. We now number fifty to sixty men, so let us elect a leader." So they drove a stake into the ground and said: "We shall run thither and he among us who is the first to reach the stake, may he become our leader". So they ran and Aksak Timur, as he was lame, lagged behind, but before the others reached the stake he threw his cap onto it. Those who arrived first said: "We are the leaders." ["But,"] Aksak Timur said: "My head came in first, I am the leader." Meanwhile, an old man arrived and said: "The leadership should belong to Aksak Timur; your feet have arrived but, before then, his head reached the goal." So they made Aksak Timur their prince.

How long did he hold his power in China?

input: In the 1970s Corea started working with vibraphonist Gary Burton, with whom he recorded several duet albums for ECM, including 1972's Crystal Silence. They reunited in 2006 for a concert tour. A new record called The New Crystal Silence was issued in 2008 and won a Grammy Award in 2009. The package includes a disc of duets and another disc with the Sydney Symphony Orchestra. Toward the end of the 1970s, Corea embarked on a series of concerts and two albums with Hancock. These concerts were presented in elegant settings with both pianists dressed formally and performing on Yamaha concert grand pianos. The two traded playing each other's compositions, as well as pieces by other composers such as Bela Bartok. In 1982, Corea performed The Meeting, a live duet with the classical pianist Friedrich Gulda. In December 2007 Corea recorded a duet album, The Enchantment, with banjoist Bela Fleck. Fleck and Corea toured extensively for the album in 2007. Fleck was nominated in the Best Instrumental Composition category at the 49th Grammy Awards for the track "Spectacle". In 2008 Corea collaborated with Japanese pianist Hiromi Uehara on the live album Duet (Chick Corea and Hiromi). The duo played a concert at Tokyo's Budokan arena on April 30. In 2015 Corea reprised the duet concert series with Hancock, again sticking to a dueling-piano format, though both also had synthesizers at their station. The first concert in this series was played at the Paramount Theatre in Seattle, and featured improvised music along with iconic songs from each of the duo and standards from other composers.
