New York Times: John Glenn, American Hero of the Space Age, Dies at 95.
“John Glenn, a freckle-faced son of Ohio who was hailed as a national hero and a symbol of the space age as the first American to orbit Earth, then became a national political figure for 24 years in the Senate, died on Thursday in Columbus, Ohio. He was 95.
Finally, 36 years after his Mercury flight, in the last months of his final Senate term, he got his wish for a return to orbit. […] At 77, he became the oldest person to go into space.”
NASA has a lot of material and further links on their John Glenn page.
