William Ross Ashby (1903-1972) was a British pioneer in the fields of cybernetics and systems theory. He is best known for proposing the law of requisite variety, the principle of self-organization, intelligence amplification, the good regulator theorem, building the automatically stabilizing Homeostat, and his books An Introduction to Cybernetics and Design for a Brain.
In 2003, Ross's family gave his journals, papers, and correspondence to the British Library, London. Then, in March 2004, on the last day of the W. Ross Ashby Centenary Conference, they announced the intention to make his journal available on the Internet. Four years later, this website fulfilled that promise, making this previously unpublished work available on-line.
The biography describes Ross's life in more detail than has previously been available in the public domain, and includes many photographs from the family's private albums. Various other information and resources can be accessed via the navigation frame on the left.
In July 2017, Mick Ashby presented the ethical regulator theorem at the ISSS 2017 Vienna conference, which builds upon the good regulator theorem and the law of requisite variety. For more information, see The Ethical Regulator Theorem.
