Which U.S. president set the Moon-landing goal fulfilled by Apollo 11?

John F. Kennedy set the Moon-landing goal fulfilled by Apollo 11. In a May 25, 1961 address to Congress, the president committed the United States to landing a person on the Moon and returning them safely to Earth before the decade ended.

The declaration transformed the space race from a series of short orbital flights into a national engineering program. NASA expanded its human-spaceflight effort, while Project Mercury and Project Gemini developed experience with astronaut operations, rendezvous, docking, and long-duration missions. The Apollo program then tested the command module, service module, Saturn V, and lunar module in increasingly demanding flights.

Kennedy did not live to see the achievement: he was assassinated in 1963. His successor, Lyndon B. Johnson, strongly supported the space program, and NASA administrator James Webb helped manage its growth, but the original deadline and lunar challenge belonged to Kennedy. Apollo 11 met that goal in July 1969, when Armstrong and Aldrin landed on the Moon and Collins supported them from lunar orbit.
