During which President's term of office did the first man walk on the moon?

The historic Apollo 11 moon landing occurred on July 20, 1969. At that time, Richard Nixon had been president for just six months, having been inaugurated in January of that year. While many associate the moonshot with President John F. Kennedy, who famously challenged the nation in 1961 to achieve the goal before the decade was out, the actual landing took place long after his presidency.

The Apollo program was the culmination of the Cold War "Space Race" between the United States and the Soviet Union. After Kennedy's assassination, President Lyndon B. Johnson championed the massive effort and funding required to make the ambitious goal a reality. The work and progress made throughout the Kennedy and Johnson administrations laid the essential groundwork for the mission's ultimate success.

On the day of the landing, Nixon watched the event from the White House and later spoke to astronauts Neil Armstrong and Buzz Aldrin via a telephone call to the lunar surface. He called it "the most historic phone call ever made," telling them that because of their achievement, "the heavens have become a part of man's world." Thus, while the journey began under Kennedy and was carried on by Johnson, it was President Nixon who was in office to witness its spectacular conclusion.
