THIS WEEK'S HONORARY UNSUBSCRIBE goes to Donald E. Campbell, for decades the only doctor in Stockbridge, Mass. A classic small-town physician, Campbell not only took care of every aspect of medical care for everyone in town (and sometimes their pets), he even had to develop his own x-ray films and process his own lab work. You may never have heard his name, but you've probably seen his picture: he was the model for one of Norman Rockwell's most famous paintings, "Before the Shot". The painting, made for a 1958 cover of the Saturday Evening Post magazine, shows Campbell preparing an injection for a young boy who is carefully studying the doctor's diploma. Dr. Campbell died at home in Stockbridge May 14. He was 95. (This week's most-suggested honoree: "Hitchhiker's Guide to the Galaxy" author Douglas Adams, dead May 11 in California of a heart attack at 49.)
