Who is this person?

Thanks, Eva. I wish I could say this operation, as described by Irving Stone, happened with 100% certainty. Jason Emerson writes that the evidence for the operation is "scanty and speculative." He also mentions that the operation was rarely done on children.

Irving Stone's book is not footnoted so I do not know his source for the quite detailed description of the operation which he provided in his book.
