Each class had the privilege of choosing its own secretary or director, but in addition there was to be a general secretary entrusted with the business and general interests of the academy. A treasurer was also appointed and provision made for two public meetings every year, one on the king's birthday. In later years one of these public meetings has been held on what is called 'Leibniz day,' July 11. Sessions were held weekly on Thursday afternoons. New members were nominated by the class they were expected to join, but the nomination had to be approved by the directory of the academy, which was made up of five secretaries and other officers, then by a general meeting of the academy and last of all by the king. It was decided that prizes should be offered every year and that papers of foreigners, if worthy, should be printed in the proceedings, as well as those by the active or honorary members of the academy. By the king's order the sessions of the reorganized academy were held in the castle. They began on January 24, 1743.
It is difficult to give a full history of the academy while Maupertuis was at its head. He preserved few papers. Although the roll of officers was full, he was really the academy. It was through his influence that men of distinction abroad became corresponding or honorary members, and some, at his solicitation, even came to Berlin that they might work in it and through it.
Deeply interested in the academy and writing papers to be read in its literary department, the king attended neither its private nor its public sessions. Nor till toward the end of his reign did he bid any of its members, save Maupertuis, to his palace. Even Formey, the famous secretary, was not called to Sans Souci till the king had been thirty-eight years on the throne. The social circles in Berlin and Potsdam were not quite the same. Maupertuis made the academy French in its thought and its aims. Under his guidance and that ofhis successors it was composed of a group of French scholars residing on German soil. Maupertuis was one of the most gifted men of his generation. He had great learning, was a diligent student of natural history and possessed rare powers of conversation. But his influence was. lessened by his egotism and his pessimism. Still he did his best for the academy. Its 'Memoires' were sought for in every learned circle in Europe. Membership in it was regarded by scholars as the highest honor they could receive. Its atmosphere was tolerant. There were no limits put upon research or upon free speech. Though German was not absolutely excluded, the discussions carried on in the academy were in French and the 'Memoires' were printed in French. There were more French-speaking Swiss in the academy prior to the death of Maupertuis than native-born Frenchmen or Germans. Switzerland was producing more learned men than she could sustain, and was willing they should go to Berlin or wherever else they might employ their talents to advantage.
