Théophile Ernest de Donder (French: [də dɔ̃dɛʁ]; 19 August 1872 – 11 May 1957) was a Belgian mathematician, physicist and chemist famous for his work (published in 1923) in developing correlations between the Newtonian concept of chemical affinity and the Gibbsian concept of free energy.
Frédéric Jean Edmond Swarts (2 September 1866 – 6 September 1940) was a Belgian chemist who prepared the first chlorofluorocarbon, CF2Cl2 (Freon-12) as well as several other related compounds. He was a professor in the civil engineering at the University of Ghent. In addition to his work on organofluorine chemistry, he authored the textbook "Cours de Chimie Organique." He was a son of Theodore Swarts (chemist, *1839 Antwerpen; †1911 Kortenberg, Belgium) and a colleague of Leo Baekeland.
Désiré Charles Emanuel van Monckhoven (1834–1882) was a Belgian chemist, physicist, and photographic researcher. He was also an inventor and author.
Louis Henri Frédéric Melsens (11 July 1814 in Leuven – 20 April 1886 in Brussels) was a Belgian physicist and chemist. In 1846, he became professor of chemistry at the Royal Veterinary School of Cureghem in Anderlecht, Brussels. Melsens applied the principle of the Faraday cage to lightning conductors and invented tincture of iodine for disinfection. In medical circles he became internationally famous for his research on oral administration of potassium iodide as a cure for mercury or lead poisoning.
Laurent-Guillaume de Koninck (3 May 1809 – 16 July 1887) was a Belgian palaeontologist and chemist, born at Leuven.
He studied medicine in the university of his native town, and in 1831 he became assistant in the chemical schools. He pursued the study of chemistry in Paris, Berlin and Gießen, and was subsequently engaged in teaching the science at Ghent and Liège. In 1856 he was appointed professor of chemistry in the Liège University, and he retained this post until the close of his life.About the year 1835 he began to devote his leisure to the investigation of the Carboniferous fossils around Liège, and ultimately he became distinguished for his researches on the palaeontology of the Palaeozoic rocks, and especially for his descriptions of the molluscs, brachiopods, crustaceans and crinoids of the Carboniferous limestone of Belgium. In recognition of this work the Wollaston medal was awarded to him in 1875 by the Geological Society of London, and in 1876 he was appointed professor of palaeontology at Liège. In 1882, he was elected as a member to the American Philosophical Society.He was awarded the Clarke Medal by the Royal Society of New South Wales in 1886.Publications:
