The collaboration between Albert Einstein and Maria Sklodowska-Curie

The paper discusses the friendly ties and collaboration between two eminent scientists, Albert Einstein and Maria Sklodowska-Curie. They collaborated not so much in strictly scientific matters, but rather in the field of scientists' organizations on the international forum. Such a forum was provided by the League of Nations, and in particular the International Committee for Intellectual Cooperation (Commission Internationale de la Cooperation Intellectuelle / CICI), a 12-member advisory body of the League. The task of the Committee was to work together with interested member-states in order to further ties of peaceful cooperation between them in the field of culture and science. The members of the Committee included eminent personalities, among them Maria Sklodowska-Curie and Albert Einstein. Very little is known about their work and collaboration within the CICI, but it is certainly a topic worth investigating, especially in view of the international importance of the scientific achievements of the two personages.
