Abraham Lincoln was infected with smallpox at some point in his life.

Notes on verification

Confirmed by peer-reviewed medical history study (Goldman & Schmalstieg 2007), contemporary diaries of Lincoln's secretaries, and multiple independent journalistic and historical sources. Minor scholarly debate exists only over severity of the case, not the fact of infection.
