Almost missed this one: Today is World AIDS Day (it's founded by the World Health Organization founded back in 1988 to raise awareness of the AIDS pandemic and to honor the persons who have died from HIV/AIDS).
Chicago Now has a gallery of influential and famous people who have died from the disease. Do you recognize these four? Answers in the comment.
Link - Thanks Mu!
