Alexander did translations of Sartre? How on earth did I not know about this?

He did the first translations of Sartre into English. I don't know that it's widely known. It was highlighted a couple of years ago by this article on existentialism in Alexander's own works, which turned into a really good Readercon panel last summer. I'm looking forward to them; I've never read anything of Alexander's that wasn't his (deeply formative) children's fiction.
