Smith, John Lawrence (16 or 17 Dec. 1818–12 October 1883), chemist, mineralogist, and physician, was born near Charleston, South Carolina, the son of Benjamin Smith, a wealthy merchant; his mother’s name is unknown. At a very young age, even before he could read, John Lawrence Smith demonstrated precocity in mathematics. After attending private schools and receiving a classical education at the College of Charleston, in 1835 he entered the University of Virginia, where he concentrated on science, mathematics, and engineering. Returning to Charleston in 1837, he worked for one year on a Charleston-to-Cincinnati railroad engineering project before entering the Medical College of Charleston and completing requirements for his M.D. degree in 1840. He studied in Europe for several years with Justus Liebig (who inspired him to focus his research efforts on chemistry), J. B. Dumas, Matthieu Joseph Bonaventure Orfila, and Élie de Beaumont.

Smithson, James (1765–27 June 1829), scientist and philanthropist, was born James Lewis Macie, probably in France, the illegitimate son of Hugh Smithson, later the first Duke of Northumberland, and Elizabeth Hungerford Keate Macie, a wealthy widow from Weston, England. Little is known of Macie's childhood in France. In 1782 he enrolled in Pembroke College, Oxford, where he excelled in chemistry and mineralogy. Two years later, he embarked on his first geological collecting tour, in Scotland and the Hebrides, with a group of distinguished scientists. In 1786 he received an M.A.from Pembroke College and a year later was elected a fellow of the Royal Society, London, its youngest member. He presented his first paper to the society on 7 July 1791, “An Account of Some Chemical Experiments on Tabasheer,” recounting his chemical analyses of this substance found in the hollow of bamboo canes. Thus began a career of scientific research, exacting experimentation, and specimen collecting. In 1800 he was elected to the new Royal Institution of Great Britain, an organization devoted to “diffusing the knowledge and … the application of science to the common purposes of life.”...
