The Chemical Industry Major Developments in the Chemical Industry The Chemical Industry Wonder materials and troublesome pollution SC/NATS 1840, Science and the Environment – XV The Chemical Industry 1 Major Developments in the Chemical Industry • The Chemical Industry arose mid- way through the Industrial Revolution. • It provided previously unheard of products that increased productivity, led to revolutionary new products, and transformed the economies of some nations. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 2 Gas • Johann Baptista van Helmont, Dutch scientist • 1577-1644 • Engaged in the study of “airs.” • Coined new word “gas” from Greek χαος, same root as the English word “chaos.” • Van Helmont identified gases by their sources, rather than by their composition (which was unknown). • E.g., “wild gas,” “windy gas,” “fat gas,” “dry gas,” “smoky gas,” etc. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 3 1 Coal Gas • One gas obtained was an inflammable “air” obtained from coal that burned like the flames of coal itself. • In 1760 was the first attempt to light a room by the gas from coal. • It was not very successful, and was dropped. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 4 Gas Lighting • Around 1800, Phillipe Lebon, a French engineer, produced a gas from heating wood. • It produced a soft light, which he contained in a glass globe. • He conceived of a distribution system involving concealed pipes running throughout a house. • But Lebon was attacked and killed by muggers in 1804, putting an end to his plans. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 5 James Watt and Matthew Boulton • Firm of Boulton & Watt get interested in gas. • James Watt’s sun, Gregory Watt, went to Paris to investigate and learned of Lebon’s work. • Meanwhile William Murdoch, Bolton and Watt’s chief engineer in Cornwall, sought to find a way to make a tar from coal for coating ships’ bottoms. • Accidentally he produced a gas from coal that could be used for lighting. • Because of Gregory Watt’s visit to Paris, Watt & Boulton realized the significance of Murdoch’s discovery and recalled him to their Birmingham factory. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 6 2 Coal Gas Lighting • The Boulton-Watt steam engine foundry in Birmingham’s Soho district became the first factory illuminated 24 hours a day by coal gas. • Watt & Boulton went into gas lighting as a side business. • They outfitted many British factories, e.g., the Salford cotton mill, with 900 gas lights in 1806-1807. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 7 Soho Stinks • Coal gas was not purified or washed and it burned imperfectly. • The result was a foul odor. • The Soho Foundry became nicknamed the “Soho Stinks.” • Boulton and Watt decided there were too many problems with gas lighting and they abandoned the business in 1814. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 8 The Gas Age • The Gas Light and Coke Company was set up in 1812 in London. • By F. A. Winzer (later Winsor) from Germany. • By 1816, there were 26 miles of gas mains in London. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 9 3 The Gas Age, 2 • By 1823, there were three rival companies in London north of the Thames. • Their goal was to replace the other night lighting, which was burning oils from animal fats. • Gas lighting cost only about 1/3 to ¼ as much as, say, whale oil. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 10 Pollution • Pollution was the major problem since the gas was not purified. • One suggestion (in 1833) for providing illumination indoors without bringing in the foul air was to place the light outside a window and let it shine through the glass to light the room. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 11 Pollution defeated • Solutions: • In 1840 the atmospheric burner was introduced. It mixed gas and air together before combustion. • In 1895, the gas mantle was introduced. • A glass sheath enclosed the burning flame, dissipated the glow, providing a safer and more usable light. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 12 4 Social Consequences of Gas Lighting • British philosopher Andrew Ure: • Saw gas lighting as a great liberator. • For example it meant that children could safely work 12 hour shifts in factories! SC/NATS 1840, Science and the Environment – XV The Chemical Industry 13 Social Consequences of Gas Lighting, 2 • Streets became safer at night because they were better lit. • The level of literacy and education in general went up because people could more easily read at night. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 14 Night Schools for workers • In Britain night schools were set up all over the country where factory workers could go after work and hear a lecture or study some subject. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 15 5 Night Schools for workers, 2 • The British Mechanics’ Institutes, founded in the 19th century, became the model for community colleges and trade schools catering to the adult student. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 16 Cooking with Gas • Gas was used primarily for lighting, only occasionally for warmth, and even less often for cooking. • It was only with the introduction of the gas ring in the 1860s that temperatures could be controlled enough to make gas practical for cooking on a modest scale. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 17 The End of Gas Lighting • With the innovations of the atmospheric burner and the gas mantle, most of the difficulties of gas lighting had been overcome and the process was practical for general usage. • However, just at that time, electric lighting began to be introduced and the age of gas lighting came to an end. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 18 6 Petroleum • Petroleum seepages have been known for millennia. • In the Middle East for example there are at least 30 places where petroleum seeps up to the surface of the earth naturally. • References to petroleum in various forms occur in the earliest written records. • In the 9th Century BCE, Assyrians marked sites of escaping gases as “where the voice of the gods issued forth from the rocks.” • Ancient Babylonians named the inflammable oil “naphtha” – i.e., “the thing that blazes.” SC/NATS 1840, Science and the Environment – XV The Chemical Industry 19 Early Uses of Petroleum • Naphtha was later used in the Byzantine Empire in the making of a weapon, “Greek Fire.” • Greek Fire was a mixture of crude oil and other chemicals that ignited when mixed with water. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 20 Asphalt and Tar • About the only natural form of petroleum that was originally considered useful was solid rock (asphalt) or thicker seepages that could be used to make bitumen (tar) for caulking ships’ bottoms and waterproofing. • The modern petroleum industry arose as a means to satisfy the existing demand for lighting that had been created by gas lighting. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 21 7 “Coal Oil” • James Young, assistant to British scientist Michael Faraday, in 1848 developed a lubricant from a petroleum product – a form of naphtha. • When refined further, it made excellent lighting. • He set up a company to manufacture and sell this product in Europe and America to compete with gas lighting and animal oils. • The name “coal oil” is still used in some places, but he called it paraffin illuminating oil. In America it became known as kerosene. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 22 Drilling for Oil • Impediments: • Lack of hard drills • Lack of mechanical power • Uncertain success • Early 19th century drillings sought water or salt, not oil. • Developments: • In 1830 the derrick was introduced. • In 1850 the steam engine was adapted to power drills. • Between 1840 and 1860 more than 15 borings that were looking for salt hit petroleum accidentally. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 23 Looking for Oil • G. H. Bissell, an American industrialist, considered deliberately searching for oil. • He sent a sample of oil from a Pennsylvania seepage to Yale chemistry professor Benjamin Silliman, Jr. • Silliman reported back that he thought that several new products could be obtained from the crude oil. • Bissell also got some advice on likely places to drill for oil. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 24 8 Drake’s Well • Bissell funded exploration led by his contractor Edwin L. Drake. • On August 27, 1859, after drilling 69 ½ feet through bedrock, Drake struck oil. • The Pennsylvania Oil Field began. Drake’s well in 1866 SC/NATS 1840, Science and the Environment – XV The Chemical Industry 25 The turning point in the history of petroleum • Within 15 years, the annual output of oil in the U.S. (mostly all in Pennsylvania) reached 10 million barrels of 360 lbs each. SC/NATS 1840, Science and the Environment – XV The Chemical Industry 26 The Oil Well Industry • The first big product of the petroleum industry was kerosene. • The U.S. exported it in tins worldwide to satisfy a demand for lighting. • Gasoline was the first distillate obtained in refining, but it was regarded as both useless and dangerous, so it tended to be just burnt off. • In Europe, the petroleum industry developed mostly in Russia.

    Science Museum Group Journal Lyon Playfair: chemist and commissioner, 1818–1858 Journal ISSN number: 2054-5770 This article was written by Ian Blatchford 05-04-2021 Cite as 10.15180; 211504 Research Lyon Playfair: chemist and commissioner, 1818–1858 Published in Spring 2021, Issue 15 Article DOI: http://dx.doi.org/10.15180/211504 Abstract Lyon Playfair was a multi-talented man: a scientist, administrator and politician whose life and influence deserve further research. This article concentrates on the period between 1818 and 1858, from Playfair’s birth to his appointment as Professor of Chemistry at the University of Edinburgh. His biographer (Sir Thomas Wemyss Reid) described his life as a ‘story not of adventure, but work’ and yet his record was one of energetic enterprise that had considerable impact. He was a rising star in the then fashionable world of chemistry, a favoured student of the founder of organic chemistry, Justus Liebig, and a central figure in the promotion of new ideas in agricultural science.[1] A career in science and the state saw him connected to the leading figures of both, and he played a crucial role in the conceptual and financial success of the Great Exhibition, and its legacy. His brilliance has been overshadowed by the extrovert Henry Cole, and yet Playfair was essential to the major educational reforms of their time. Component DOI: http://dx.doi.org/10.15180/211504/001 Keywords Lyon Playfair, chemistry, politics, biography, University of Edinburgh, Justus Liebig, Great Exhibition Introduction [2] Playfair was a versatile man: scientist, administrator and politician.

  • Addiewell WW1 Those Wounded, 6 Military Medalists & Awards
    Addiewell WW1 Those Wounded, 6 Military Medalists & Awards Sgt Thomas Allan An Addiewell Sergeant’s Story – Sgt Thomas Allan, who was in the regular army when war broke out, is at present home on a month’s sick leave, having just recovered from an attack of enteric fever, he tells an interesting story of his experiences while in France and Belgium. His regiment (Scots Greys) first saw action at a little village named Binch, some few miles farther on than Mons. Describing the action in his own words, Sgt Allan said that it was about two o’clock on Saturday morning of August, 21st and our men were enjoying a much needed rest, having done a forced march of 40 miles the day previous. Our patrols came in with the news that the Germans were advancing in large numbers. They very soon made their presence felt, shells began to burst in all directions, and the noise gradually became deafening. Our men put up a stubborn resistance at first, but the enemy’s preponderance in numbers soon told and eventually we were forced to retire. The covering of the retirement naturally fell to the cavalry regiments, and I can tell you we had a busy time of it trying to keep the Germans in check. Our turn eventually came however, when we came in touch with the remainder of the French Army, which by this time had been mobilised and brought up to the river Marne. A combined attack along the line set the Germans in full retreat, and so quick did they retire that is was always about every third day before the Brito-French forces could catch up with them.

  • Great Scientists
    GREAT SCIENTISTS Pathetic side of their lives An INSPIRING book especially for— Unprivileged Science Students . –An Incomplete Version ROSS NAZIR ULLAH BLANK PAGE BLANK PAGE PREFACE This book has been compiled in response of two situations; firstly those that I encountered during my teaching experience with science students and secondly talking to friends about the lives and works of scientists. In this book you will find only those scientists who got some pathetic part in their lives. I have tried my best to collect as many scientists as possible that fall in this category. Entries are not listed in alphabetical order. Each entry contains a short account of major achievements and early life followed by pathetic moments in their lives. An important aim is to provide unprivileged students with a challenge. I am particularly concerned about science students obtaining low scores in the exams. It has been designed for personal possession as a guide and for consultation in colleges and universities. All first efforts to develop a genre in a particular direction suffer from the constraints of space and time, and this may have led us to fall short of our self- imposed standards. I became aware in this selection that how fascinating history of scientists’ biography excitingly unveils their values and attitudes. This book has two chief features; firstly, short biographical sketch and secondly, the tragic moments in one person’s life. However, these two features also prove to be the major limitations of mentioning some important, informative, interesting and scientific achievements in the lives of the scientists. I very much welcome feedback from readers, which will enable to improve its coverage or treatment in future editions.

Further material in the RCSEd Museum Name of Creator: Simpson, J Y; Fergusson W; etc Language of Material: English. Some French; some Latin Level of Description: item; file Date(s) of Description: 1981; revised 2009; 2012 Biographical History/Provenance: James Simpson (1811-1870) (pictured centre) was born in Bathgate, West Lothian, seventh son of a baker. He was educated at the local school and went to Edinburgh University at the age of 14. Too young to graduate, he became a Licentiate of the Royal College of Surgeons of Edinburgh in 1830 before graduating in 1832. He became Professor of Midwifery at Edinburgh University in 1840, Physician to Queen Victoria in 1847, President of the Royal College of Physicians in 1850 and Baronet in 1866. A man of enormous energy and great personal charm, Simpson was a keen controversialist and much loved physician. His contributions to obstetrics are overshadowed by his discovery of the anaesthetic effects of chloroform in November 1847. After ether was discovered in 1846, Simpson was quick to use it to relieve the pains of labour, earning the gratitude of countless women and the condemnation of some members of the church and the medical profession. Simpson was a doughty advocate of the cause of general anaesthesia and his final vindication came when Queen Victoria had chloroform at the birth of Prince Leopold in 1853.

DISPELLING THE DARKNESS: TYPES OF CANDLES AND THE APPROPRIATENESS OF EACH FOR THE MID-19 TH CENTURY Virginia Mescher Today, with the variety and ease of artificial lighting, one often takes for granted an abundance of light, whenever or wherever it is desired. During the 1860s, light did not occur with the flip of a switch. People were accustomed to a much lower level of illumination; pockets of light within an area were utilized and shared among several people, rather than the entire room being brightly lit. The amount of light that one flame can produce is surprising when one’s eyes adjust to a lower level of illumination. There were a number of lighting devices used in the mid-nineteenth century but candles were probably the most prevalent. From reading various household accounts, approximately one hundred pounds of candles per year were used by an average, middle-class household. Lamps, such as whale oil, camphene (burning fluid), coal oil, and kerosene, were used to some extent but there were a greater number of references, in primary sources, to candles. With candles, one did not have to be concerned with spilled lamp fuel; broken or exploding lamps or replacement of chimneys, wicks and other lamp hardware. Candles also offered portability and were more economical than lamps. A candle is not just a candle.

  • Thomas Graham Event
    THE INSPIRATION OF THOMAS GRAHAM, CHEMIST An appreciation and history of his influence on the development of the Department of Pure & Applied Chemistry at the University of Strathclyde, Glasgow. Colin Suckling Freeland Professor of Chemistry 2006 1 THE INSPIRATION OF THOMAS GRAHAM, CHEMIST At the ‘Andersonian’. The tag ‘A place of useful learning’ is well-known as the founding characteristic of the new University in Glasgow set up in the Will of John Anderson in 1796. It’s something that the University of Strathclyde, grown from Anderson’s vision, still strongly holds. But it takes more than a paper, even one with a strong visionary catch phrase, to make something happen. It takes people, usually many people. The story of Anderson’s University as an institution has often been told but less has been said about the development and impact of the various fields of science, engineering, and medicine. Our story is about chemistry and the remarkable influence and inspiration of one professor of chemistry at Anderson’s University, Thomas Graham. Much more could be said in this story but in a sleeve booklet, we must be content with exemplification and illustration. Chemistry was one of the first subjects to be taught at Anderson’s University. The first professor of chemistry was Andrew Ure who had a high reputation in analytical chemistry but also had responsibilities for natural philosophy in Anderson’s University. When the University managers decided to separate responsibilities for natural philosophy and chemistry, Andrew Ure resigned. This created to opportunity for Thomas Graham who, through his own research and through his influence on his students, coupled the rapidly growing science of chemistry with the vision of ‘useful learning’.
