Anne Keegan, a distinguished Chicago newspaper reporter, has died at home after a long wasting illness of several years that she chose not to acknowledge. Even last December, when she cracked some ribs earlier in the day and her pain was undisguisable, her illness was not allowed to cause Anne and her husband, Leonard Aronson, to cancel their annual Christmas party, a party at which carols were sung, the piano was played, the hired kitchen help sang songs from the old country before departing for the night, and smoking was not restricted to the front porch. Large dogs roamed freely and threatened the roast beef.
