Marius Sophus Lie (1842–1899) was a pioneer of study of (and almost solely devoted to) the groups of continuous and smooth transformations, mainly motivated by symmetries of differential equations. He is considered a founder of the theory of Lie groups and Lie algebras, whose global theory however has been completed only with works of Élie Cartan.
