Are you sure you're not thinking of Wilder Penfield? Daniel Schacter has him
as a Canadian neurosurgeon in his _Searching for Memory:the Brain,the Mind
and the Past_. Penrose is another chap altogether if I'm not mistaken, but I
could very well be mistaken.

I'm not familar with Penfield (?) enough to know all of what he was about,
but the engram concept for a memory trace goes back AFAIK to a German
biologist named Richard Semon (1859-1918), though it is commonly attributed
to Karl Lashley. Daniel Schacter is the expert on Semon. His book _Forgotten
Ideas, Neglected Pioneers: Richard Semon and the Story of Memory_ is a
There was some holographic or hologram dude who came around after Lashley,
but I can't remember who off the top of my head.
