Does anyone know about this experiment?

I read about this ages ago and I can’t remember where or the specifics. But I’d love to.

It was done sometime in the ‘50’s or ‘60’s. A man had a head injury from an accident as a kid and suddenly when he was an adult, he lost his ability for short term memory. He would always think it was the day before. Kind of like the movie 50 First Dates. A scientist worked with him to study this condition, and he eventually discovered that people have two kinds of memories. Your emotional memory (everything you know about your identity and family, etc) and your motor skills memory (everything your body automatically knows, like how Jason Bourne could still know how to fight and yet not know himself).

If anyone knows any idea what I’m talking about, please send me a link or maybe it was in a book or elaborate on the vague details of the experiment/story.
