Deletion of John S. Greenspan

Comment: His title of distinguished professor (emeritus) passes #C5, he has a 1990 honorary doctorate from Georgetown and a 1996 honorary professorship at the University of Buenos Aires, and these and his 2012 ADA Gold Medal Award for Excellence in Dental Research https://www.ada.org/en/publications/ada-news/2012-archive/july/dr-john-greenspan-awarded-2012-ada-gold-medal-for-aids-efforts seem likely to pass #C2. He has heavy citations for his work on AIDS-related oral lesions, enough to convince me of a pass of #C1. His books ''AIDS And the Dental Team'' and ''Textbook of Oral Cancer'' may (if they have enough reviews, which I haven't checked) give him another pass of . The article is kind of cv-like but AfD is not for cleanup
