His name is Clive Wearing.
He remembers little of his life before 1985; he knows, for example, that he has children from an earlier marriage, but cannot remember their names. His love for his second wife Deborah, whom he married the year prior to his illness, is undiminished & he greets her joyously every time they meet.
Despite having retrograde as well as anterograde amnesia, and thus only a moment-to-moment consciousness, Wearing still recalls how to play the piano and conduct a choir – all this despite having no recollection of having received a musical education.
Here is a video about Clive: [x]
