"William Ross Ashby (1903-1972) was a British pioneer in the fields of Cybernetics and Systems Theory. He is best known for the Law of Requisite Variety, for his books Design for a Brain (1952) and An Introduction to Cybernetics (1956), and for building the Homeostat.
In January 2003, Ross's daughters gave his archive materials to The British Library, London. Then, in March 2004, at the end of the W. Ross Ashby Centenary Conference, they announced that they would make Ross's Journal available on the Internet. This web site fulfills that promise, making this previously unpublished work available on-line."
