If Lincoln was assassinated in 1865 and the IGAS show was filmed in 1956, then the eyewitness would have necessarily been 90 years old if he was taken to Ford’s Theatre as a newborn. To be old enough to witness and remember the event, he would need to be a few years older than that.
And, of course, people in their 90s are often found to have faulty memories so...
He was 96 and he was 5 when he was at Ford’s Theater.
If you watched the entire clip he said he wasn’t aware of what happened to Lincoln, he did see Booth jump to the stage where he broke his leg and that was his most vivid memory.
1956-1865=91 years. He was 5yo at the time (born in 1860). Nothing disputable here.
He was 5 years old and he didn’t know the president had been shot. What he saw was Booth jumping from the balcony into the president’s viewing box. He thought the guy had fallen. (Booth broke his leg in the process.)
He was born in 1860 and was five years old when he witnessed the assassination. If you watch the clip, he says that all he remembers is someone falling from the balcony and hurting his leg. He was more concerned about the man who hurt his leg, not understanding that the President had been shot.
