В 1838 году родился Поль Эмиль Лекок де Буабодран, открывший галлий

The native of the town of Cognac would go in for wine making at first like his ancestors, yet was carried away by chemistry and discovered four elements, including the one predicted by Mendeleyev. He named it gallium – out of a sense of patriotism, as many people thought (Gallia is the same as ancient France). However, evil tongues suspected the chemist in immodesty, as gallus and lecoq are the Latin and French for word cock.
