Yes, he's the same William Morris who lends his name to today's William Morris Company, known far and wide for their tapestries and wallpapers. Apparently, he was also a big deal poet in the Victorian Age. He was also a communist, and would say as much to anyone within earshot, loudly. Though he claimed to be a proponent of socialism, William Morris was basically an anarchist at heart, demanding what would basically have been a lawless post-apocalyptic wasteland.
Except he wanted to ensure that there was no divorce. Because if I've learned anything from history, it's that laws are awful, unless they're against women, in which case we need more of them.
