Skallagrigg is a 1987 novel written by William Horwood and influenced by Horwood's relationship with his own daughter Rachel, who has cerebral palsy. It is notable in that it foresaw the importance of adaptive computer technology in the lives of future generations of disabled people. It is also an early example of discourse on disability politics, treatment of the disabled throughout history, and hit-or-miss relations and perceptions between the disabled and able-bodied communities.
