To Dr. Sintsof: „Veuillez agréer l’expression de ma vive reconnaissance de votre lettre si aimable du 17/30/XII 1906 et veuillez vous faire l’interprete auprès de la Société Mathématique de Karkof de mes sentiments de profonde gratitude de l’honneur que la Société a bien voulu me faire en m’appelant son membre honoraire.“ His mathematical contributions are connected chiefly with the theory of functions, which today is called complex analysis. Mittag-Leffler was a convinced advocate of women's rights and was instrumental in making Sofia Kovalevskaya a full professor of mathematics in Stockholm, as the first woman anywhere in the world to hold that position.
As a member of the Nobel Prize Committee in 1903, he was responsible for inducing the committee to award the prize for Physics jointly to Marie and Pierre Curie, instead of just Pierre. Mittag-Leffler founded the mathematical journal Acta Mathematica (1882), with the help of King Oscar's sponsorship, and partly paid for with the fortune of his wife Signe Lindfors, who came from a very wealthy Finnish family. He collected a large mathematical library in his villa in the Stockholm suburb of Djursholm. The house and its contents were donated to the Academy of Sciences as the Mittag-Leffler Institute..

To a colleague: „Je vous prie de vouloir bien faire connatire à la Société Mathématique de Charkow que Madame Mittag-Leffler et moi, à l’occasion de mon 70ième anniversaire le 16 mars 1916, avons légué ma bibliotheéque avec ma villa à Djurholm et tout ce que nous possédons à une institution internationale pur les mathématiques supérieures. Vous trouverez plus de détails dans un opuscule que je me permets de vous adresser ensebmle avec cette lettre.
