Gösta Mittag-Leffler

Magnus Gustaf Gösta Mittag-Leffler (16 March 1846 to 7 July 1927) was a Swedish mathematician whose contributions are connected chiefly with the theory of functions that today is called complex analysis. He founded the prestigious periodical Acta Mathematica and was its editor for 40 years. He was known as an advocate for female intellectual workers in an era when women were often overlooked, took great trouble to obtain for Sofia Kovalevskaya a position as full professor of mathematics at Stockholm University, and induced the Nobel committee to recognize Marie Curie as an equal contributor. In Helsinki he lectured on elliptic functions and basic analysis, and through his former teacher Charles Hermite he became acquainted with Paul Appell, Émile Picard and Henri Poincaré.
