Several years ago, the Lincoln Group of D.C. had a speaker who had been raised at the hospital during the 1940s and 50s. His father was in charge of the institution at that time, but I cannot remember his name.

I just read a 2006 article online that wanted to insert once again the theory that both Mr. & Mrs. Lincoln suffered from syphilis. However, the article stated that an autopsy was performed on Mary Lincoln and a brain tumor was found. Did I miss something along the way?
