Chapter 2 Beginnings 2.1 Introduction At the start of the twentieth century, organic chemistry was not yet 75 years old as a separate and legitimate sub-discipline of the science. Considerable progress had been made in these first seven decades, and the stage was set for the dramatic advances in the science to come in the following century. Most practicing organic chemists are familiar with many of the great German, French and English organic chemists whose work helped the fledgling discipline grow, but few are familiar with the role that Russian organic chemists of the nineteenth and early twentieth century played in the development of the science. And this is in spite of the fact that many of the named rules and reactions that one studies in the first course in organic chemistry are, in fact, of Russian origin. It is the intent of this book to help rectify that deficiency. -
Supplementary Figure 1: Interconnected Multiplex with Six Nodes in Two Layers (A and D) and Corresponding Aggregated Networks (B and E)
Supplementary Figure 1: Interconnected multiplex with six nodes in two layers (A and D) and corresponding aggregated networks (B and E). The nodes are ranked by their eigenvector centrality in each layer separately, in the aggregated and in the whole interconnected structure (C and F). Case A, B and C. Nodes 1 and 3 have a key role in the multilayer, being bridges between the two layers. In a collaboration network they would represent scientists working on two different research areas who allow information to flow from one subject to the other. While nodes 1 and 3 gain centrality from their connections to \hubs" on different layers, they also gain centrality from their own counterparts in other layers, making them important in the multilayer network. In the aggregated network their versatility disappears, because the information is washed out by projecting on a single layer, where nodes 2 and 6 are still \hubs" but it is not possible to capture the importance of nodes 1 and 3 in bridging different areas. Case D, E and F. This example shows how aggregating the full information on a single network introduces a spurious symmetry between nodes 2, 3, 4 and 6 that is not present in the multilayer, except for 2 and 4. The resulting score in the aggregate is not able to capture the difference between these nodes (corresponding to a degeneration in the eigenspace) while it is evident that, for instance, node 6 is more central than node 3 because of its direct connection to node 1 { the \hub" { in layer 1. -

Antoine Paul Nicolas Franchimont 1844-1919 (Leiden) and Charles Adolphe Wurtz 1817-1884 (Strasbourg) Barrett Honors College Chemistry 113 Footnote 18 Project Pamela T. Hoang November 21, 2003 Antoine Paul Nicolas Franchimont (1844-1919) was appointed to the position of professor of chemistry at The Leiden Institute of Chemistry in 1874 along with J.M. van Bemmelen (Driessen). The Leiden University has boasted a proud, venerable reputation of chemistry since it was founded in 1575. Approximately 300 years later, Franchimont became the first chair of organic chemistry in Europe at Leiden. He received his Ph.D. in 1871 at the young age of 27. Three years later, Franchimont was promised a “new laboratory, but he had to wait twenty-seven years before he could move into a new building in the Hugo de Grootstraat” (Driessen). After the new laboratory opened in 1918, Franchimont unfortunately died a year later; however, chemistry flourished in the laboratories in the centre of Leiden for approximately seventy years. The number of students increased from one or two per year to about one hundred in the late 1960’s (Driessen). Franchimont is also credited with co-discovering triphenylmethane and anthraquinone. In addition, he also studied the acylation of sugars and cellulose, nitroamino compounds, and the chemistry of hydrogen azide, urea, urethanes, nitric acid, and oxalic acid (Bachas). Lastly he is attributed to discovering "tetryl," which was a widely, popular explosive in the early 1900s (Bachas).

Before Radicals Were Free – the Radical Particulier of De Morveau
Review Before Radicals Were Free – the Radical Particulier of de Morveau Edwin C. Constable * and Catherine E. Housecroft Department of Chemistry, University of Basel, BPR 1096, Mattenstrasse 24a, CH-4058 Basel, Switzerland; [email protected] * Correspondence: [email protected]; Tel.: +41-61-207-1001 Received: 31 March 2020; Accepted: 17 April 2020; Published: 20 April 2020 Abstract: Today, we universally understand radicals to be chemical species with an unpaired electron. It was not always so, and this article traces the evolution of the term radical and in this journey, monitors the development of some of the great theories of organic chemistry. Keywords: radicals; history of chemistry; theory of types; valence; free radicals 1. Introduction The understanding of chemistry is characterized by a precision in language such that a single word or phrase can evoke an entire back-story of understanding and comprehension. When we use the term “transition element”, the listener is drawn into an entire world of memes [1] ranging from the periodic table, colour, synthesis, spectroscopy and magnetism to theory and computational chemistry. Key to this subliminal linking of the word or phrase to the broader context is a defined precision of terminology and a commonality of meaning. This is particularly important in science and chemistry, where the precision of meaning is usually prescribed (or, maybe, proscribed) by international bodies such as the International Union of Pure and Applied Chemistry [2]. Nevertheless, words and concepts can change with time and to understand the language of our discipline is to learn more about the discipline itself. The etymology of chemistry is a complex and rewarding subject which is discussed eloquently and in detail elsewhere [3–5]. -

History of the Chemical Industry, 1750 to 1930
History of the Chemical Industry 1750 to 1930 – an Outline Copyright: David J M Rowe, University of York (1998) Introduction The aim of this survey is to sketch the history of the chemical industry (mainly in Britain), for the period 1750 to 1930, and its relationship with contemporary political, social, and scientific developments; much detail will inevitably be omitted for brevity. It will be argued that the development of the chemical industry arose largely in response to contemporary social needs; and that whereas the development gained much from scientific discoveries, problems encountered in industry also provided fertile ground for scientific enquiry. It is often supposed that pure science is a necessary precursor of technological development but a study of history reveals many cases in which scientific understanding of technology lags behind the technology, sometimes by a long way. Political Background Some major events: • American War of Independence 1775-1783 • French Revolution and Napoleonic Period Revolution 1789, First Empire (Napoleon I) 1804-1815 • American Civil War 1861-1865 • Unification of Italy; completed 1870 • Franco-Prussian War 1870-71 • Unification of Germany; foundation of German Empire 1871 • First World War 1914-1918 • Second World War 1939-1945 Emergence of Britain as the dominant world economic power between the end of the Napoleonic Wars (1815) and the First World War, but rise of Germany as a strong economy after 1871. Emergence of the USA as a powerful economy towards the end of the 19th century, to become -

The Royal Society of Chemistry Presidents 1841 T0 2021
The Presidents of the Chemical Society & Royal Society of Chemistry (1841–2024) Contents Introduction 04 Chemical Society Presidents (1841–1980) 07 Royal Society of Chemistry Presidents (1980–2024) 34 Researching Past Presidents 45 Presidents by Date 47 Cover images (left to right): Professor Thomas Graham; Sir Ewart Ray Herbert Jones; Professor Lesley Yellowlees; The President’s Badge of Office Introduction On Tuesday 23 February 1841, a meeting was convened by Robert Warington that resolved to form a society of members interested in the advancement of chemistry. On 30 March, the 77 men who’d already leant their support met at what would be the Chemical Society’s first official meeting; at that meeting, Thomas Graham was unanimously elected to be the Society’s first president. The other main decision made at the 30 March meeting was on the system by which the Chemical Society would be organised: “That the ordinary members shall elect out of their own body, by ballot, a President, four Vice-Presidents, a Treasurer, two Secretaries, and a Council of twelve, four of Introduction whom may be non-resident, by whom the business of the Society shall be conducted.” At the first Annual General Meeting the following year, in March 1842, the Bye Laws were formally enshrined, and the ‘Duty of the President’ was stated: “To preside at all Meetings of the Society and Council. To take the Chair at all ordinary Meetings of the Society, at eight o’clock precisely, and to regulate the order of the proceedings. A Member shall not be eligible as President of the Society for more than two years in succession, but shall be re-eligible after the lapse of one year.” Little has changed in the way presidents are elected; they still have to be a member of the Society and are elected by other members.
