On this day, April 25th 1865, a 6-year old Theodore Roosevelt watched the funeral procession of President Abraham Lincoln in New York City. With him at the second story window (corner of Broadway and 14th) was his brother Elliot.
Interestingly, though the photograph has been famous since it was taken, only recently was the little face at the window discovered to be the future Governor of New York and President of the United States.
