Gösta Mittag-Leffler was a Swedish mathematician who, in 1882, founded the international journal Acta Mathematica, and was its chief editor for 45 years. He studied in Paris under Charles Hermite and in Berlin under Karl Weierstrass, and made significant contributions to analysis. His best known work concerned the analytic representation of a one-valued function and culminated in the Mittag-Leffler theorem. Since he took a special interest in Georg Cantor's discoveries much of Cantor's work was published in Acta Mathematica. Inscribed on the mantelpiece of Mittag-Leffler's home – now a research institute – in Djursholm is the epitaph: "Number is the beginning and end of thought. Thought gave birth to number but reaches not beyond. ML 1903"
