1. Joseph Achille Le Bel (21 January 1847 in Pechelbronn – 6 August 1930, in Paris, France) was a French chemist. He is best known for his work in stereochemistry. Le Bel was educated at the École Polytechnique in Paris. In 1874 he announced his theory outlining the relationship between molecular structure and optical activity. This discovery laid the foundation of the science of stereochemistry, which deals with the spatial arrangement of atoms in molecules. This hypothesis was put forward in the same year by the Dutch physical chemist Jacobus Henricus van 't Hoff. Le Bel wrote Cosmologie Rationelle (Rational Cosmology) in 1929.

2. Pierre Eugène Marcellin Berthelot (25 October 1827 – 18 March 1907) was a French chemist and politician noted for the Thomsen-Berthelot principle of thermochemistry. He synthesized many organic compounds from inorganic substances and disproved the theory of vitalism. He is considered as one of the greatest chemists of all time.
He was born in Paris, France, the son of a doctor. After doing well at school in history and philosophy, he became a scientist.

3. Yves Chauvin (born October 10, 1930) is a French chemist and Nobel Prize laureate. He is honorary research director at the Institut français du pétrole and a member of the French Academy of Science. Chauvin received his degree from the Lyon School of Chemistry, Physics and Electronics in 1954.

4. Arne Wilhelm Kaurin Tiselius (10 August 1902 – 29 October 1971) was a Swedish biochemist who won the Nobel Prize in Chemistry in 1948.

5. Sir Joseph John "J. J." Thomson, OM, FRS[1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel laureate. He is credited with discovering electrons and isotopes, and inventing the mass spectrometer. Thomson was awarded the 1906 Nobel Prize in Physics for the discovery of the electron and for his work on the conduction of electricity in gases.

6. Born in Dundee, he was educated at the High School of Dundee, and though had passed the entrance examination for the University of St Andrews at sixteen, he instead went for three years to the flax industry, entering the University of Edinburgh in 1882, graduating B.Sc. in 1885 and D.Sc. in 1886. He then spent three years in Germany, working with Ludwig Claisen, Adolf von Baeyer and Wilhelm Ostwald. Following a Ph.D at the University of Leipzig in 1889, he returned to Britain, working in Edinburgh and University College, London, before being appointed professor of chemistry at the University of Dundee in 1894. In 1908 he returned to Edinburgh to succeed Alexander Crum Brown as professor.
Walker's main research interest was in physical chemistry. He investigated methods of electrolysis in the synthesis of dicarboxylic acids, the dissociation constants of acids and bases, and measured molecular weights by freezing point depression. While he is personally credited with no truly major discoveries, his most important role was as a populariser of the new and controversial physical chemistry theories of Ostwald, van't Hoff and Arrhenius in the English speaking world. This he did through his 1890 translation of Ostwald's Grundriss der allgemeinen Chemie (Outlines of General Chemistry), and his own textbook Introduction to Physical Chemistry (1899), which became a set text in many British universities.
Walker was elected a Fellow of the Royal Society in 1900, and was awarded a Davy Medal in 1926. 7. Pierre Fauchard (1678 – March 22, 1761) was a significant French physician, credited as being the "father of modern dentistry". He is widely known for his book, Le chirurgien dentiste, "The Surgeon Dentist" 1728, where he described the basic oral anatomy and function, signs and symptoms of oral pathology, operative methods for removing decay and restoring teeth, periodontal disease (pyorrhea), orthodontics, replacement of missing teeth, and tooth transplantation. His book is said to be the first complete scientific description of dentistry. Fauchard's text was followed by others who continued to expand the knowledge of the dental profession throughout Europe.

8. William Harvey (1 April 1578 – 3 June 1657) was an English physician. He was the first to describe completely and in detail the systemic circulation and properties of blood being pumped to the body by the heart, though earlier writers had provided precursors of the theory.[1][2] After his death the William Harvey Hospital was constructed in the town of Ashford, several miles from his birthplace of Folkestone.

9. Moritz Kaposi (Hungarian: Kaposi Mór) (born 23 October 1837 in Kaposvár, Hungary – 6 March 1902 in Vienna, Austria) was a Hungarian physician and dermatologist who discovered the skin tumor that received his name (Kaposi's sarcoma).

10. Carl Adolph von Basedow (March 28, 1799 – April 11, 1854) was a German physician most famous for reporting the symptoms of what could later be dubbed Graves-Basedow disease, now technically known as exophthalmic goiter.
