I was 15 years old when I read this story in Life magazine for February 9, 1963. Such is the power of the imagery--the description of Lincoln in his casket 36 years after his death--that I never forgot it. For years I told people the story of the boy who witnessed the opening of Lincoln's coffin in 1901, before Lincoln was permanently sealed away in a concrete tomb.
After my current reading I remembered thinking in 1963 that the assassination of a president was something that happened in the past, and had little relevance to modern times. A few months later, in November, John F. Kennedy was assassinated. I came to understand with others of my generation what it feels like when it happens.
