That is… Edwin Booth, brother of John Wilkes Booth, saved the life of Robert Lincoln, Abraham Lincoln’s son.
The incident occurred just over 1 year before the Lincoln Assassination in a New Jersey train station.
Robert Lincoln, who was pushed up against a train by a large crowd, fell into the platform gap. Suddenly, he was lifted by his coat collar to safety by none other than Edwin Booth, a famous Shakespearean actor.
Edwin Booth, unlike his brother, was a Lincoln supporter and a strict Unionist.
