HM (also known as "H.M." and "Henry M.," born 1926 in Connecticut) is an anonymous memory impaired patient who has been widely studied since the late 1950s and has been very important in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that studies brain injury to infer normal psychological function.
