Post Chronicle, May 19, 2007 GALVESTON - Two Texas medical researchers say President Abraham Lincoln was suffering from a severe case of smallpox when he delivered his Gettysburg Address. The report, based on descriptions of Lincoln's illness in November and December 1863, appears in the current issue of the Journal of Medical Biography, the Houston Chronicle said Friday. Dr. Armond S. Goldman, an emeritus professor in Galveston's University of Texas Medical Branch, said Lincoln first complained of illness on his way to Gettysburg on Nov. 19, 1863. He was carried on a stretcher to the White House from the train station that night and remained in bed for many days.
