==Name in the introductory paragraph== 
 I've always been told that using "Dr." & "Ph.D." in the same name was incorrect, as the Ph.D. automatically conferred the status of doctor.   However, I'm not sure what to do in this case.  Since he is so well-known as "Dr. Martin Luther King, Jr.," the normal approach of dropping "Dr." and keeping "Ph.D." doesn't seem to be the best answer, even though it's the one most style guides seem to endorse.  Would someone more intimately familliar with the article like to take a swing at changing it, or suggesting an alternative?
