Robert Bunsen
Robert Wilhelm Eberhard Bunsen (; 30 March 1811 – 16 August 1899) was a German chemist. He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff. The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff. Bunsen also developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organic arsenic chemistry. With his laboratory assistant Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use. Early life and education Bunsen was born in Göttingen, Germany in 1811, in what is now the state of Lower Saxony in Germany. Bunsen was the youngest of four sons of the University of Göttingen's chief librarian and professor of modern philology, Christian Bunsen (1770–1837). After attending school in Holzminden, Bunsen matriculated at Göttingen in 1828 and studied chemistry with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edith Pechey
Mary Edith Pechey (7 October 1845 – 14 April 1908) was one of the first women doctors in the United Kingdom and a campaigner for women's rights. She spent more than 20 years in India as a senior doctor at a women's hospital and was involved in a range of social causes. Family and Edinburgh Mary Edith Pechey was born in Langham, Essex, to Sarah (''née'' Rotton), a lawyer's daughter who, unusually for a woman of her generation, had studied Greek, and William Pechey, a Baptist minister with an MA in theology from the University of Edinburgh. After being educated by her parents, she worked as governess and teacher until 1869. Lutzker notes that "Her mother also was competent in Greek and other studies and both parents possessed - along with their questing nonconformist minds - a deep and serious love of learning." The Campaign to study medicine After Sophia Jex-Blake's sole application to study medicine at the University of Edinburgh was turned down, she advertised in The Scot ...

Keith Medal
The Keith Medal was a prize awarded by the Royal Society of Edinburgh, Scotland's national academy, for a scientific paper published in the society's scientific journals, preference being given to a paper containing a discovery, either in mathematics or earth sciences. The Medal was inaugurated in 1827 as a result of a gift from Alexander Keith of Dunnottar, the first Treasurer of the Society. It was awarded quadrennially, alternately for a paper published in: Proceedings A (Mathematics) or Transactions (Earth and Environmental Sciences). The medal bears the head of John Napier of Merchiston. The medal is no longer awarded.

Royal Society Of Edinburgh
The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellows. The Society covers a broader selection of fields than the Royal Society of London, including literature and history. Fellowship includes people from a wide range of disciplines – science & technology, arts, humanities, medicine, social science, business, and public service. History At the start of the 18th century, Edinburgh's intellectual climate fostered many clubs and societies (see Scottish Enlightenment). Though there were several that treated the arts, sciences and medicine, the most prestigious was the Society for the Improvement of Medical Knowledge, commonly referred to as the Medical Society of Edinburgh, co-founded by the mathematician Colin Maclaurin in 1731. Maclaurin was unhapp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Conan Doyle
Sir Arthur Ignatius Conan Doyle (22 May 1859 – 7 July 1930) was a British writer and physician. He created the character Sherlock Holmes in 1887 for ''A Study in Scarlet'', the first of four novels and fifty-six short stories about Holmes and Dr. Watson. The Sherlock Holmes stories are milestones in the field of crime fiction. Doyle was a prolific writer; other than Holmes stories, his works include fantasy and science fiction stories about Professor Challenger and humorous stories about the Napoleonic soldier Brigadier Gerard, as well as plays, romances, poetry, non-fiction, and historical novels. One of Doyle's early short stories, " J. Habakuk Jephson's Statement" (1884), helped to popularise the mystery of the ''Mary Celeste''. Name Doyle is often referred to as "Sir Arthur Conan Doyle" or "Conan Doyle", implying that "Conan" is part of a compound surname rather than a middle name. His baptism entry in the register of St Mary's Cathedral, Edinburgh, gives "Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Wöhler
Friedrich Wöhler () FRS(For) Hon FRSE (31 July 180023 September 1882) was a German chemist known for his work in inorganic chemistry, being the first to isolate the chemical elements beryllium and yttrium in pure metallic form. He was the first to prepare several inorganic compounds, including silane and silicon nitride. Wöhler is known for seminal contributions in organic chemistry, in particular, the Wöhler synthesis of urea. His synthesis of the organic compound urea in the laboratory from inorganic substances contradicted the belief that organic compounds could only be produced by living organisms due to a "life force". However, the exact extent of Wöhler's role in diminishing the belief in vitalism is considered by some to be questionable. Biography Friedrich Wöhler was born in Eschersheim, Germany, and was the son of a veterinarian. As a boy, he showed interest in mineral collecting, drawing, and science. His secondary education was at the Frankfurt Gymnasium. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Volhard
Jacob Volhard (4 June 1834 – 14 January 1910) was the German chemist who discovered, together with his student Hugo Erdmann, the Volhard–Erdmann cyclization reaction. He was also responsible for the improvement of the Hell–Volhard–Zelinsky halogenation. From 1852 to 1855 he studied chemistry at the University of Giessen, and afterwards, furthered his education at the University of Heidelberg. For two years he worked as an assistant under Justus von Liebig at the University of Munich, and in 1860/61 studied with August Wilhelm von Hofmann in London. In 1863 he obtained his habilitation at Munich, where he subsequently became an associate professor. In the meantime, he worked in the Institute of Plant Physiology at the Bavarian Academy of Sciences (1865–76).
