Sigmar Polke has died after a long-term battle with cancer.
I have been a devotee of his eclectic work for several years now and it is a great loss for the art community that his voice is now silenced. Yet, I suppose it is some comfort that the legacy of his oeuvre will allow his voice to continue.
Sigmar Polke will be the subject of an upcoming AoTW. In the meantime, you can read more here.
