George Henry Corliss (June 2, 1817 – February 21, 1888) was an American mechanical engineer and inventor, who developed the Corliss steam engine, which was a great improvement over any other stationary steam engine of its time.
 The Corliss engine is widely considered one of the more notable engineering achievements of the 19th century.
 It provided a reliable, efficient source of industrial power, enabling the expansion of new factories to areas which did not readily possess reliable or abundant water power.
 Corliss gained international acclaim for his achievements during the late 19th century and is perhaps best known for the "Centennial Engine", which was the centerpiece of the 1876 Centennial Exposition in Philadelphia.
Gilbert Blount (1819–1876) was an English architect working mostly for Catholic Churches.
 He started his career as a civil engineer under Brunel and became superintendent of the Thames Tunnel works.
 He then worked for Sydney Smirke, and then was appointed as architect to Cardinal Wiseman, the Catholic Archbishop of Westminster.
The history of the Irish language begins with the period from the arrival of speakers of Celtic languages in Ireland to Ireland's earliest known form of Irish, Archaic Irish, which is found in Ogham inscriptions dating from the 3rd or 4th century.
 After the conversion to Christianity in the 5th century, Old Irish begins to appear as glosses and other marginalia in Latin manuscripts, beginning in the 6th century.
 It evolved in the 10th century to Middle Irish.
 Early Modern Irish, otherwise known as Classical Irish, was a literary language that represented a transition between Middle and Modern Irish.
 It was used by writers in both Ireland and Scotland until the 17th century, in the course of which slowly but surely writers began writing in the vernacular dialects, Ulster Irish, Connacht Irish, Munster Irish and Scottish Gaelic.
 As the number of hereditary poets and scribes dwindled under British rule in the early 19th century, Irish became a mostly spoken tongue with little written literature appearing in the language until the Gaelic Revival of the late 19th century.
 The number of speakers was also declining in this period with monoglot and bilingual speakers of Irish increasing adopting only English: while Irish never died out, by the time of the Revival it was largely confined to the less Anglicised regions of the island, which were often also the more rural and remote areas.
 In the 20th and 21st centuries, Irish has continued to survive in Gaeltacht regions and among a minority in other regions.
 It has once again come to be considered an important part of the island's culture and heritage, with efforts being made to preserve and promote it.
Isambard Kingdom Brunel {'1': ", '2': ", '3': ", '4': "} ( ; 9 April 1806 – 15 September 1859), was an English mechanical and civil engineer who is considered "one of the most ingenious and prolific figures in engineering history", "one of the 19th century engineering giants", and "one of the greatest figures of the Industrial Revolution, [who] changed the face of the English landscape with his groundbreaking designs and ingenious constructions".
 Brunel built dockyards, the Great Western Railway, a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels.
 His designs revolutionised public transport and modern engineering.
Ecology is a new science and considered as an important branch of biological science, having only become prominent during the second half of the 20th century.
 Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics.
 Its history stems all the way back to the 4th century.
 One of the first ecologists whose writings survive may have been Aristotle or perhaps his student, Theophrastus, both of whom had interest in many species of animals and plants.
 Theophrastus described interrelationships between animals and their environment as early as the 4th century BC.
 Ecology developed substantially in the 18th and 19th century.
 It began with Carl Linnaeus and his work with the economy of nature.
 Soon after came Alexander von Humboldt and his work with botanical geography.
 Alfred Russel Wallace and Karl Möbius then contributed with the notion of biocoenosis.
 Eugenius Warming’s work with ecological plant geography led to the founding of ecology as a discipline.
 Charles Darwin’s work also contributed to the science of ecology, and Darwin is often attributed with progressing the discipline more than anyone else in its young history.
 Ecological thought expanded even more in the early 20th century.
 Major contributions included: Eduard Suess’ and Vladimir Vernadsky’s work with the biosphere, Arthur Tansley’s ecosystem, Charles Elton's "Animal Ecology", and Henry Cowles ecological succession.
 Ecology influenced the social sciences and humanities.
 Human ecology began in the early 20th century and it recognized humans as an ecological factor.
 Later James Lovelock advanced views on earth as a macro-organism with the Gaia hypothesis.
 Conservation stemmed from the science of ecology.
 Important figures and movements include Shelford and the ESA, National Environmental Policy act, George Perkins Marsh, Theodore Roosevelt, Stephen A. Forbes, and post-Dust Bowl conservation.
 Later in the 20th century world governments collaborated on man’s effects on the biosphere and Earth’s environment.
The history of women in engineering predates the development of the profession of engineering.
 Before engineering was recognized as a formal profession, women with engineering skills often sought recognition as inventors, such as Hypatia of Alexandria (350 or 370–415 AD), who is credited with the invention of the hydrometer.
 In the 19th century, women who performed engineering work often had academic training in mathematics or science.
 Ada Lovelace (1815–1852) was privately schooled in mathematics before beginning her collaboration with Charles Babbage on his analytical engine that would earn her the designation of the "first computer programmer."
 Hertha Marks Ayrton (1854–1923), a British engineer and inventor studied mathematics at Cambridge in the 1880s.
 Elisa Leonida Zamfirescu (1887–1973) is one of the first female engineers in Europe.
 In the early years of the twentieth century, a few women were admitted to engineering programs, but they were generally looked upon as curiosities by their male counterparts.
Bert Mosselmans (born 1969) is a professor of economics and philosophy and Dean of Vesalius College, Brussels, Belgium.
 And professor of economics and philosophy at University College Roosevelt, Middelburg, the Netherlands.
 He received a MSc in Business Engineering (1992), a MA in philosophy (1994) and a PhD in economics (1999) from the Vrije Universiteit, Brussels, Belgium.
 His research focuses on the history of economic thought, mainly the 19th century and the first half of the 20th century, and with a special interest in the history of microeconomics and industrial organization.
 He has published extensively on the history of economic thought and the history of philosophy, most notably on William Stanley Jevons, a 19th-century British philosopher and economist.
 His research appeared in journals such as The European Journal of the History of Economic Thought and History of Political Economy.
The Banū Mūsā brothers ("Sons of Moses"), namely Abū Jaʿfar, Muḥammad ibn Mūsā ibn Shākir (before 803 – February 873), Abū al‐Qāsim, Aḥmad ibn Mūsā ibn Shākir (d. 9th century) and Al-Ḥasan ibn Mūsā ibn Shākir (d. 9th century), were three 9th-century scholars who lived and worked in Baghdad.
 Of Persian descent, they are known for their "Book of Ingenious Devices" on automata (automatic machines) and mechanical devices.
 Another important work of theirs is the "Book on the Measurement of Plane and Spherical Figures", a foundational work on geometry that was frequently quoted by both Islamic and European mathematicians.
The story of oil production in California began in the late 19th century.
 In 1903, California became the leading oil-producing state in the US, and traded the number one position back-and forth with Oklahoma through the year 1930.
 s of 2012 , California was the nation's third most prolific oil-producing state, behind only Texas and North Dakota.
 In the past century, California’s oil industry grew to become the state’s number one GDP export and one of the most profitable industries in the region.
 The history of oil in the state of California, however, dates back much earlier than the 19th century.
 For thousands of years prior to European settlement in America, Native Americans in the California territory excavated oil seeps.
 By the mid-19th century, American geologists discovered the vast oil reserves in California and began mass drilling in the Western Territory.
 While California’s production of excavated oil increased significantly during the early 20th century, the accelerated drilling resulted in an overproduction of the commodity, and the federal government unsuccessfully made several attempts to regulate the oil market.
Illinois Institute of Technology, commonly called Illinois Tech or IIT, is a private Ph.D.-granting research university located in Chicago, in the U.S. state of Illinois, with programs in engineering, science, psychology, architecture, business, communications, industrial technology, information technology, design and law.
 It traces its history to several 19th century engineering and professional education institutions in the United States.
