Abraham Lincoln, the 16th president of the United States, is most famous for his leadership during the American Civil war, his decision to free the slaves in 1863, and his eventual assassination. What gets less attention is his hat. Lincoln was already a giant at 193 cm. During his time, the average height was 172 cm, so he didn’t need any help standing out from the crowd. Despite his stature, he chose to wear a high top hat.
