Charles-Irénée Castel, abbé de Saint-Pierre (18 February 1658 – 29 April 1743) was a French author whose ideas were novel for his times. His proposal of an international organisation to maintain peace was among the first in history, with possible exceptions such as George of Poděbrady's ''Tractatus'' (1462–1464) and Émeric Crucé. He influenced Rousseau and Kant. Provided by Wikipedia
