Rotating Photos/Easter Egg

My six readers have probably noticed that I've been rotating the photo backdrops to the blog title. Well, I've added the name of the person pictured. This name is a hotlink to some reputable online treatment of that person's life and thought, so feel free to click away!

There's no rotational schedule: I wing it. Feel free to suggest persons; remember that the title of the blog is "Free Expression," so err on the side of those who devoted themselves to that end.
