A cool letter of recommendation for John Nash, found at this Twitter page.
I got a letter of recommendation once that said, “Al is a machine,” but I never got the “genius” thing.
In a related note, the “machine” reference — from a person I didn’t even like — helped me to realize I was living my life in an unbalanced, screwed-up way. I took my first long leave from work (sabbatical) shortly after I read that.
