My greatgrandfather Peter McIntyre fought with the Union, in an Indiana regiment. He was wounded in the head and we think that he was the first to have a steel plate placed is skull. Is that possible? Thanks

Definitely call. If they don't know, they can help you find out who can answer your questions.

The museum demonstrated a lot of surgical advancements during the war, but I'm sorry I don't remember that I read about such procedures. I'm sure the museum would be happy to answer such a question.

You should call them, I'll bet they would be happy to answer your question. http://www.civilwarmed.org/contact/
