Though not really a category theorist Klaus Keimel was well known to many people on this list for his work in topology and domain theory. After a half year of heavy illness he died in the morning of Saturday 18.November. For me he was mentor and a very good friend. Many people will remember him not only for his great mathematical oevre but also for being the impressively kind and pleasant person he was.
