NASA moon landing engineer John C. Houbolt dies at 95, AP
"John C. Houbolt, an engineer whose contributions to the U.S. space program were vital to NASA's successful moon landing in 1969, has died. He was 95. His efforts in the early 1960s are largely credited with convincing NASA to focus on the launch of a module carrying a crew from lunar orbit, rather than a rocket from earth or a space craft while orbiting the planet."
