He's an interesting character in our story, although Mr. Menzies doesn't go into a great deal of detail about him until the end of the book, he does mention him in the introduction, which I am still laboring through. I, of course, wanted to know a little more.
But you know what I found out? There seems to be a lot of disagreement online about what is actually factual in this guy's life. But at least I found a nice picture.
