Neither I have met him, so I shouldn´t comment on him, I guess.
About"his" numbers: At first glance it may look strange and odd to use legal actions in such a matter. I think that what he did was a very clever thing to do. From my point of view, people are just copying his work from top to bottom.It must be quite frustrating for him. Nowadays, people in general don´t seem to care much about copyright laws, do they? I guess I am not perfect either....
(Background: Galen has added a couple of figures to his work that were purposly wrong. The idea was to trap people who copied his work.)
