Entities and eponyms: two each, and a painter--"175" years on.

Time frames are always dictated by the calendar. Kaposi was born 175 years ago, Carl Heitzmann one year before, and lupus erythematosus (LE) just one year later. Strawberry Hill and its lord played not too small a role in unraveling some details of LE and the "hemorrhagic sarcoma to-be." Kaposi (1837-1902) lent his name to one of the above two syndromes, but he published extensively on both in the same year, same journal, and same volume (German Archives, volume 4, 1872). The literary "birth" of chronic discoid LE (CDLE) (1838) trails the master's by one year. Carl Heitzmann's birth precedes it, also by one--justification enough to deal with the three in one.
