Paul Emile Lecoq de Boisbaudran

He analysed the spectra of 35 elements using a Bunsen burner or electric spark to induce luminescence and consequently discovered the lanthanides samarium (Sm), dysprosium (Dy) and europium (Eu).

When-Discovered the elements gallium (1875), samarium (1880), and dysprosium (1886)-In 1876, he was awarded the Chevalier of the Legion d'Honneur. Awarded the Davy Medal in 1879.-He studied at the Ecole Polytechnique in Paris, under the organic chemist Charles-Adolphe Wurtz.

His Impact

BiographyIn 1858 Lecoq de Boisbaudran began working in the family wine business, though he pursued scientific studies in his spare time. He took up the study of spectroscopic analysis and began a search for new elements in 1859. In 1869 Mendeleyev published his periodic table, from which he predicted the existence and properties of several unknown elements, including one he called eka-aluminum. When Lecoq de Boisbaudran discovered gallium, he found it had the predicted properties of eka-aluminum, and thus it was the first of Mendeleyev’s elements to be uncovered. His discovery paved the way for the general acceptance of the periodic table.

Boisbaudran’s family belonged to the ancient Protestant nobility of Poitou and Angoumois, and had been wealthy prior to the religious persecutions of the seventeenth and eighteenth centuries. When Boisbaudran was born, however, his father and uncle were corproprietors of a wine business at Cognac. His mother, daughter of an army officer, was a learned woman who taught her son classics, history, and foreign languages. Although he had no formal schooling, Boisbaudran worked through the course books of the École Polytechnique, Performing experiments in a home laboratory equipped by his uncle.
