Astronaut Neil Armstrong, the first person to walk on the moon, died Saturday. He was 82. Armstrong solidified his place in history on July 20, 1969 when he left the first human footprint on the surface of the moon. NPR's Neal Conan remembers the man his family called a "reluctant hero."

About 10,000 people live in Wapakoneta, Ohio — half that in the 1960s. In 1969, the town wanted to honor the most famous Wapakonetan (so far), the first man to step on the moon, Neil Armstrong. So they had a parade. Here's the front page of the paper that day.

The Middle Class The very rich and the very poor are often the subjects of modern presidential campaigns. The rich come up every time there is a battle over tax reform and who should pay their fair share and the poor are often in the middle of battles over so-called entitlement programs and budget priorities. But for the vast millions of Americans in the middle class, this may be the most important election in decades. The Middle Class is being discussed with great fervor on both sides and most experts agree that the next President will be the candidate who appeals most to these voters.

Phyllis and Darren Sudman started Simon's Fund in 2005, after their 3-month-old son Simon died in his sleep. They learned later that Simon had an undetected silent heart condition.

Regina Spektor plays the piano so loudly, she has to convince piano tuners to adjust the instrument to her liking.
